Ideas from the Outings Leaders' Workshop, continued from April newsletter Part 3 - Challenging Situations Compiled by Ruth Munson and Gail Gregory from the Outings Leaders' Workshop held January 17, 2009. What situations have you found when leading and how have you overcome them?

A. Keeping the Group Together

• Pace may vary depending on the sightings of the day. • Offshoot groups lagging at one spot may slow the pace. • Participants may move at differing paces. • Ask participants to report leaving the walk. • Ask back-up person to watch for stragglers so leader knows who has left and who may be lost! • After lunch is an especially difficult time to keep track of the group.

B. Seeing and Hearing

• Identify other experts in the group to aid in answering questions. • If one person is dominating the questions suggest having a later discussion. Ask the group if anyone else has a

question. • A heckler. We were surprised at this being reported as a situation. We can only hope it won't happen again! • Socialize but don't drown out the leader! Step aside to have your personal conversations. • Allow time for enjoying special vistas and sightings.

C. Physical Challenges

• Inclement weather. Remember that the leader can decide to cancel a walk at the meeting place if conditions warrant.

• Find a shady spot for information sharing on a hot day. • Make group aware of poison ivy in an area you are passing. • Arrange for mutual help in case of accident (see next summary for the Safety discussion in detail).

PRESIDENT’S REPORT The TFN is a multi-faceted organization, and our members appreciate nature in a variety of ways. For some, it is the simple delight of experiencing hopeful signs of spring – the conk-la-reeee of Red-winged Blackbirds, pussy willows bursting forth and scampering chipmunks. For people of scientific mind, the appeal may be studying the amazing interactions within nature – how flowers are designed to attract the insects they rely on for pollination, or the indispensable role of fungi in the health of a forest. Some of us take delight in watching behaviour – birds building their nests and feeding their young. Some TFN members have become expert in certain fields, and share their knowledge and enthusiasm by writing articles for the Newsletter. Thank you, Marilynn Murphy, for your continuing “Bird of the Month” series.

On the first Saturday of each month, a Nature Arts outing enables members to combine love of nature with artistic talents, and our newsletter is enriched by the images they capture, by drawing, painting or photography. Thank you, Gail Gregory, for the charming watercolour on this month’s front cover. I thoroughly enjoyed participating in the outing at Allan Gardens on March 7th co-led by Barry Singh, a talented photographer, and Joe Bernaske, who introduced a new aspect of nature arts – writing. The initial subject was haiku, a nature-oriented poetic form from Japan which has been adopted and modified by North Americans. I felt Joe captured its essence well:

• A crystallized moment of reality sensed with heightened awareness and expressed with simple imagery

• A reminder to pause and be present in the moment to the details around us by using all our senses

• A whole new way of seeing something

Joe shared examples, including some he had written, and challenged us to try our hand at it as we explored the greenhouses. This proved more difficult than I had anticipated! Joe wrote this one following our outing:

Cabbage Whites flying upward circling each other dancing into fall

We are fortunate to have gifted haiku-writers among our members, and enjoy printing their poems in the Newsletter. Thank you, Joe, for initiating the writing idea, and we look forward to learning other genres on future nature arts outings.

But the TFN is about more than appreciating and enjoying nature. We also recognize the importance of protecting and preserving it. The garlic mustard pulls on May 22nd provide an opportunity to do this (see pages 5 and 15 and for details). I hope many of you will participate. Thank you, Bob Kortright, for organizing this project.

As you will see, we have a wonderful assortment of outings for you to enjoy during the spring and summer months, where I hope to see many of you. If you have special holidays planned, I hope they will include encounters with nature. I am looking forward to re-visiting Rondeau Provincial Park – one of my favourite places – and participating in the Huron Fringe Bird Festival.

Please be sure to renew your TFN membership in good time, so as not to miss your September newsletter (see page 27).

MONTHLY MEETING REPORT

After the Ice Age: The First Peoples of Ontario Sunday, April 5, speaker: Peter Storck, formerly of the Royal Ontario Museum, and author of Journey to the Ice Age: Discovering an Ancient World

It is generally accepted that the original peopling of the Americas was the result of the migration of Asians across the Bering land bridge. They spread throughout the continent – to South America in the south and Nova Scotia in the east. In 1929, evidence of the existence of Paleo-Indians had been found in the southeastern United States. But when did they come to Ontario?

Peter’s pioneering work on this question and how he made his discoveries make a fascinating story. The Paleo-Indian stage of occupation is characterized by the use of projectile points. These early hunters are said to have been here 10,000 to 12,000 years ago when northern Ontario was still under ice and glacial Lake Algonquin lapped what we know as southern Ontario.

How does an archaeologist know where to look for evidence? Peter walked, beachcombing into the past. By walking the ancient raised shorelines formed over the last several thousand years, he searched for the sites where he might find the tools and campsites of early man.

His first major discovery, close to Alliston, was a drumlin in a farmer’s field. A drumlin is a geological term for an elongated hill deposited and shaped by glacial ice. Here, he found spear points, hammer stones, knives, spear blanks and tools for working leather.

However, this was not enough to establish that the ancient people had been there when the lake was present. For that he needed organic material such as charcoal and remains of extinct animals to put the people in the place. The difficulty is that what was once the bottom of lakes and lagoons is now our rich

farmland and the act of ploughing disturbs the archaeological record.

Peter’s second major discovery occurred north of Uxbridge. Here he found 2000 pieces of stone – chips off the tools being sharpened through a process called flintknapping, a sophisticated technology. He also found the contents of what had once been a fire pit.

These 293 pieces of animal bone, weighing 290 grams, were probably smashed by the people to make soup and then put into the fire. They make the largest collection of ancient animal bones east of the Mississippi.

The bones, tiny fragments, were finally identified. One belonged to the paw of a hare, the second, caribou toe bones and the third, an arctic fox. So with both tools and the animal remains discov-ered, the ancient people are placed in time and we know something of their life.

Peter then went looking for other parts of the landscape of their lives and the stone used in their tools and weapons provided a clue. It

was a flint-like substance, white chert. Three years later, a geological colleague found the source, up near Collingwood.

Peter’s pioneering work leaves questions for future exploration. For instance, why did these Paleo-Indians use white chert, sourced in a snow belt when they probably entered Ontario from the south?

For those interested in the details of this story, I highly recommend his readable book, Journey to the Ice Age, for details of his findings as well as the story of how an archaeologist works. At the back is a self-guided tour keyed to the narrative in the book. You, too, can drive into ice age Ontario and beyond!

As announced in the April newsletter, please join fellow TFN members to pull garlic mustard on May 22 from 10 a.m. to about noon at Warden Woods or South Humber Park (for directions see Outings page 5). There will be city staff at each site to show us how it is done. Wear comfortable clothes, sturdy closed-toed shoes, bring drinking water and sunscreen.

GARLIC MUSTARD REMOVAL Informat on drawn from BEAN s Removal protocol for garlic mustard in Ontario, ROM Field Guide to Wildflowers of Ontario, Ottawa F e d Natura sts F etcher W d fe Garden Gar c Mustard factsheet, and TFN s photo arch ve.

Garlic mustard (Alliaria petiolata) is a shade-tolerant biennial that produces a cluster of basal leaves in its first year, and a leafy flowering stem up to 1 m tall in the second year. It has a strong garlic odour, especially if the leaves are bruised. Garlic mustard is a member of the mustard family (Brassicaceae).

The first year basal leaves are long-stalked and kidney-shaped, from 3 to 17 cm across. The leaves on the second year stem are alternate, stalked, triangular, 3 to 6 cm long, with coarsely toothed margins.

The flower cluster is a raceme of small, white, four-petalled flowers, 6 to 7 mm wide. Flowers are produced from April to June.

The fruits are narrow capsules, up to 6 cm long, on short stout stalks. Flowers and fruits develop over time from the bottom of the raceme up to the top, so you may see the long capsules at the base of the raceme while there are still flowers opening at the top.

Large plants in suitable habitats may produce over 2,700 seeds. In dense stands in woodland habitats, seed production can range from 9,500 to over 100,000 seeds per square metre per year. When mature, the capsules burst open and can throw seeds several meters. Further distribution is primarily by humans and other animals inadvertently carrying seeds, or mud containing seeds. Natural or human-made roads and trails thus become prime corridors for invasion.

Populations spread an average of 5.4 m/year, which may not sound like a lot until you add it up: 6,400 km2/year in North America! Garlic Mustard can dominate forest groundcover within 5 to 7 years of introduction.

BIRD OF THE MONTH BLACK-THROATED BLUE WARBLER

It was not until I joined the Toronto Field Naturalists with its wonderful leaders, especially the late Helen Smith, who began drawing my attention to them, that I knew such gorgeous birds as warblers existed in Toronto. A whole new world opened up. May is now my favourite month of the year, the best chance to see 25 or more warbler species during their spring migration. Within this family of beautiful birds, the Black-throated Blue Warbler was one of the first I learned and remains a favourite. A never-to-be-forgotten sight was of a Black-throated Blue Warbler and a Scarlet Tanager feeding in full view against a background of bright yellow forsythia, a startling contrast of primary colours. That May day a cold wind had driven the tanager down to shrub level and, after several minutes, finally drove me away, leaving the birds where I’d found them.

Although warblers are best appreciated with the help of binoculars, the “blue” is more obliging than many and sometimes allows good looks even without binoculars. The male’s deep blue, black and white pattern is unlike any other warbler and makes him easy to recognize and remember. The little white patch on the wing, often referred to as the pocket-handkerchief, is quite distinctive on the male and helps us recognize the otherwise drab olive female. So different are the sexes in appearance that early observers considered them different species. Unlike those “confusing fall warblers” which appear as pale imitations or in some cases very different from their spring glory, blues change little with the seasons. The male’s song seems

to me louder, simpler and easier to recognize than that of many warblers.

Insects comprise the main warbler diet, for some species their entire food source. The Black-throated Blue Warbler, however, has somewhat more varied tastes. Besides insects, it also eats some fruit and occasionally seeds, mainly in fall and winter. In the fall, blues have also been known to consume sap from sapsucker holes and at feeders they will eat suet and peanut butter. This flexibility must help the rare lingerer, like the two recorded in last winter's Toronto Christmas Bird Count. Each warbler species has its own methods of catching insects. Blues tend to move a little more slowly and generally at lower levels than many warblers and both these habits make it easier for us to observe them. Occasionally blues can also be seen gathering insects on the open ground.

For nest sites, Black-throated Blue Warblers prefer dense shrubs in deciduous or mixed forest interiors. This necessitates travelling beyond Toronto and in Ontario the densest breeding concentrations of blues are in the Southern Shield and to a lesser extent in the Northern Shield. The Atlas of the Breeding Birds of Ontario 2001 - 2005 reports an expansion in southern Ontario, probably due to forest regeneration. More good news can be found in the Toronto Ornithological Club's spring warbler survey, conducted for more than 35 years. While that survey shows marked declines for many warblers migrating through the city, for blues “no significant trend up or down” has been detected.

Warblers migrate mainly at night. They cross Lake Ontario when conditions are favourable and Toronto is well situated as a stop-over both in spring and fall. For several weeks warblers can be found in the city's parks, cemeteries and backyards, preparing for the next leg of their journey. Other than the abundant Yellow Warbler, very few warblers stay in the city to nest. Around the end of May blues disappear from Toronto until the southbound journey begins in August. By mid-October all but that rare straggler are gone and unless we follow them to the Caribbean, we can only look forward to next May for their reappearance. The bird seen by Frances Money in Cuba may be the one you see in Toronto.

KEEPING IN TOUCH Two Does and a Fawn Those who know me realize I rarely birdwatch without rubber boots. This is because I like to go through wetlands and swamps where most people hate to go. Most of the green areas of Toronto are in river valleys. Finding wild tableland which is forested is highly unusual. The norm in Toronto is, as soon as you climb a hill from a valley you find someone’s private property. I was pleasantly surprised when birding north of Sheppard on the east Don. I climbed a hill and found forested tableland. The area was covered with deer tracks so I was hopeful of finding some animals. I was not disappointed for in the distance I saw a white tail flashing. The doe did not move too far from me and sat down with her ears perked up. I tried to avoid scaring her so made my way back to the bike path. I went on a route through the wet lowlands hoping to flush a woodcock. I didn’t have much luck finding early spring arrivals. While I was walking on the paved path two more deer were jumping over logs on the far bank of the river. They appeared to be a doe and year old fawn. Although I only saw 18 species of birds, seeing 3 deer made the hike more than worthwhile. Next week may bring in some bluebirds, meadowlarks or flickers. This time of year is always exciting as you never know what you may discover.

Wind Speed in Colour While many people probably know about the weather beacon on top of the Canada Life building on University Avenue (which shows if the temperature is

going up or down, and if it is raining or snowing), few people know about the new wind speed indicator on a building near the corner of Yonge and Carlton, opposite the TFN office.

The beacon was installed as a piece of art, and is called “The Harbinger” (not of spring). Instead, colours indicate wind speed. If the colour is blue, there is little wind, but as the wind increases, the colour changes to green, then red, and finally white, with many shades in between. The beacon can be seen by anyone walking on Yonge in the evening. It can also be seen from as far away as Union Station.

My wife and I have been members for several years. I am submitting a couple of photos of interesting insects from our native plant garden in downtown Toronto. One is of a Nessus sphinx moth that was feeding on our milkweed in the summer of 2008. The other is of two milkweed bugs mating (presumably). Keep up the great work with the newsletter.

John Teshima

This is the last newsletter of the 2008-2009 season. Thanks to all members who sent in articles, letters, book reviews, reports, poems, artwork and photographs. And a big thank you to Newsletter Committee members for your hard work, especially co-editor, Wendy Rothwell, without whom your newsletter might not arrive on time!

Please keep the newsletter in mind when you’re on summer outings, and send us your observations of and on Toronto nature for next season’s issues.

Tommy Thompson Park (TTP) – Highlights of 2008 By Andrea Luger, Restoration Services Division, Toronto and Region Conservation Authority (TRCA) 2008 was a busy year at TTP, also known as Leslie St. Spit. Although it was a cold and snowy winter, staff of TRCA started the year by installing various structures around the park such as wood duck and owl boxes and fish cribs. Later, the soil slope on the edge of Cell One was altered to make a vertical wall that Bank Swallows can burrow into and build their nests. (A vertical slope offers protection from mammalian predators.) Log tangles and brush piles were installed on the Toplands and around Triangle Pond for small mammals, and turtle nesting habitat was created near several wetlands.

Log tangles, root wads and large boulders were placed on the ice a few metres off the shoreline of Embayment C. When the ice melted they naturally fell into position, creating structural habitat, feeding and spawning opportunities for fish, and substrate for invertebrates. Logs emerging above the water are ideal for turtle basking and waterfowl roosting. In the summer native aquatic vegetation was planted along the shoreline to increase biodiversity, reinforce stability, and provide food and cover for both aquatic and terrestrial species.

Creation of a two-basin wetland on the Toplands continued throughout the year. Topsoil was added and contoured. A water control structure was placed between the two basins in order to manipulate water levels independently in each basin so that shorebirds of varying sizes can benefit. The wetland was filled with water pumped from Lake Ontario, and mud from the base of Triangle Pond was spread across several areas to increase the number and diversity of invertebrates available for shorebirds. We are looking forward to the arrival of migrating shorebirds in the spring!

Although fine materials have been placed above the construction rubble and clean dredgeate that forms the land base of TTP, the soil profile at TTP is atypical of

natural areas, with organic soils largely absent. This makes TTP less than ideal for plant growth. Organic matter provides plant roots with the nutrients and micro-organisms they need and improves the moisture holding capacity of the soil, allowing plants to take up more water. To improve conditions, planting nodes were created with topsoil imported from local develop-ment sites and these areas were planted or seeded with native species. Nine hundred trees and shrubs were planted. Herbaceous species were planted in wet meadows and sand dunes, increasing plant diversity, improving soil stability and enhancing wildlife habitat by providing food and cover, including over-wintering and nesting habitat.

Non-native invasive species are a concern in some areas of TTP: the shoreline of Triangle Pond is predomi-nantly composed of common reed; some meadow areas in the park have been taken over by dog strangling vine; and purple loosestrife is found near wetlands. Physical removal techniques were used to control dog-strangling vine and common reed before their seeds had matured and dispersed. Vegetation surveys were also completed around Cell One and the four Embayments. These annual surveys allow us to map natural succession and changes in vegetation community structures.

As non-functioning light standards in the park are removed there are fewer perches available for raptors to rest and survey the surrounding area for foraging opportunities. To compensate for this, a 7 m raptor pole has been installed in a meadow area near Embay-ment D. The pole, which has a snake hibernaculum at its base, is expected to become a favourite location for park visitors looking for birds of prey – already a Peregrine Falcon is enjoying this new vantage point! More poles will be erected in the coming months.

Continued on p. 19.

FOR READING The Songs of Insects By Lang Elliott and Wil Hershberger Houghton Mifflin Co., 228 pages, $26.95, includes 70-minute CD.

This is a very handy new book to help you enjoy the sounds of late summer. It covers 75 singing insects - crickets, katydids, grasshoppers and cicadas - in the eastern and central US and Canada. Both authors are well-known, Elliott for his bird songs and Hershberger for insect songs. There is a brief background introduction to the insect groups such as how and why they sing, but most of the book is devoted to species identification. The 75 species covered are separated into 6 types of crickets, 5 types of katydids, 2 of long-horned grasshoppers and 2 of cicadas. There is a short introduction for each type followed by usually 2 pages for each species. The left page has a picture of the species on white, a range map, sonogram and some pertinent comments about the species. The right page has a full-page photograph of the species on vegetation. The photographs are outstanding! When there are several species that look similar there are also additional drawings of parts of the insect that would distinguish them. I should mention that all the photographs are of live insects; I don't know how they got the crickets to stay still.

The CD is amazing. It is difficult to actually see insects singing; those that sing during the day often hide themselves and those that sing at night have perfect cover. Also, some insect songs are so high-pitched that many older people can't hear them. For this CD, the authors used a device that lowers the pitch into a range where one's hearing is still normal. That said, I did have to turn the volume way up for a couple of the katydid songs. Each species on the CD is introduced with a brief narrative, followed by the song. If there is a difference in the song because of temperature, e.g. cold cricket/warm cricket, both songs are recorded.

The book closes with a few tips on which insects you might want to keep as household musicians for a while. Coneheads are attractive but their songs are loud and harsh while cricket trills and chirps are quite pleasant! This is a fun and informative book.

Carol Sellers Field Guide to the Dragonflies and Damselflies of Algonquin Park and the Surrounding Areas By Colin Jones and Matt Holder, illustrations by Peter Burke and Andrea Kingsley. The Friends of Algonquin Park, P.O. Box 248, Whitney ON K0J 2M0. Available only from www.algonquinpark.on.ca, 263 pages, $28.95.

This new field guide is an important contribution to our knowledge of odonates. Many guides cover only dragonflies or damselflies; this guide covers both in great detail. Although the title refers to Algonquin Park, the guide is very complete for Ontario. It covers 135 species, omitting only a few species from southwestern and far northern Ontario.

Each species is given a complete description noting its identification markers, a comparison to similar species, notes on habitat and behaviour, flight period, status (common, rare, etc.) and its range. A good-size coloured drawing shows the top and/or side view. Often there are black-and-white drawings of specific details that could be used to identify the species. The depth of information conveyed by the drawings is extremely informative.

This book didn't come out until fall so I haven't had a chance to use it, but I'm certainly looking forward to it.

Tommy Thompson Park Highlights continued from previous page The new trail system installed in 2007 was a big hit with park visitors. By separating the trails by their main uses, people had more room to discover the park at their leisure, reducing the number of conflicts with cyclists. The three main trail systems are the Primary Pedestrian Trail for walking and jogging, the Multi-Use Trail for cyclists and the Nature Trail for nature observers.

Many exciting restoration projects are scheduled for TTP in 2009. There will be spring and fall plantings of native trees and shrubs, wildflower plantings in the summer, improvements to trails, and shoreline stabilization and wetland habitat improvements in the Embayments.

EXTRACTS FROM OUTINGS LEADERS’ REPORTS Port Union Waterfront Trail, March 4, led by Karin Fawthrop A Red-tailed Hawk followed us from Rouge Hill GO station to the Highland Creek bridge. Other than 2 cardinals and 2 Rock Doves, the only birds were waterfowl. The Long-tailed Ducks were the noisiest. On the beach next to the creek there was a beaver munching on sticks. Everyone had a good view.

Humber Bay East, March 10, led by Bob Kortright Although the mink, Black-backed Gulls and two Horned Grebes were the only slightly unusual sightings, many in the group were also delighted with good views of all three merganser species, Redhead, scaup, Bufflehead, goldeneye, and juvenile and adult plumages of three gull species. For many, sightings of Red-winged Blackbird, Common Grackle, and even Gadwall were first of the spring.

Col. Sam Smith Park, March 14, led by Wendy Rothwell On this bright sunny morning, 35 eager participants turned out to see both winter waterfowl and newly returned migrants. In the lagoon, we watched White-winged Scoters and Horned and Red-necked Grebes. The voices of Red-winged Blackbirds and Song Sparrows were a delightful sign of spring. And it was a thrill to see four Trumpeter Swans fly over in formation.

Ashbridges Bay, March 17, led by Margaret Catto Twenty-three bird species in total. We heard a Belted Kingfisher and saw Mourning Doves nest-building in a spruce. American Robin and Song Sparrow were singing, also Red-winged Blackbird and Common Grackle.

Leslie Street Spit, March 28, led by Bob Kortright The warm sunny forecast led almost 50 members and friends to visit the Spit to see birds – 8 lasted the full 11 km. Those who left early missed the cormorants which appeared to arrive during the day, since we saw none until well after lunch and they first appeared behind us! About half the species were those (mostly waterfowl) which have been around all winter. The blackbirds, cowbirds, grackles, Killdeer, and Song Sparrows have been back for several weeks. More recent signs of spring included the Ring-necked Ducks, Red-necked Grebes, cormorants, Turkey Vulture, Northern Harrier, woodcock, kingfisher, kinglets, creepers, butterflies, coltsfoot in bloom, pussy willows, and garter snakes

seen in a couple of places–males apparently attempting to mate with females emerging from hibernacula. The mockingbird was seen by some at the base of the Spit. The woodcock flushed in our midst during our lunch stop, dropping back down into the shrubbery so quickly many did not see it. Unfortunately many also missed perhaps the most unusual sight for the day – a Sandhill Crane flying high above us to the west, where they are more often seen. A group led by the president of the Toronto Ornithological Club spotted a Western Grebe far offshore, but we were unable to find it.

LOON by Heather Cadsby

Many people like birds. Birds travel a lot. Many people can’t sit still. They get jealous, go weird. Some birds are weird. Take the loon for instance. Underwater He spreads his wings And flies after fish. On the surface He runs. In the air He moves like a hunchback. And that’s not to mention His crazy feet Goofy jewellery And wild cry. Loons have no use for people. Many people like loons.

CITIZEN SCIENCE Citizen Science is a term used to describe the participation of citizens in the collection of data for scientific analysis. From glass eels in the Hudson River watershed and lichens in Toronto to bird migration across North America, these data allow scientists to track species distributions and population numbers for use in analysing many different ecological issues such as the effects of climate change, invasive species, habitat loss, and pollution. Ideally, these analyses will lead to better government policy and management. Programs may include extensive training or simply involve a few minutes of instruction. Here is a sampling of some projects you can get involved in. A new citizen science program, Pollination Canada, collects observations from the Canadian public for a nationwide survey of pollinators. The program monitors insect populations and diversity in gardens, parks, along country roads – anywhere flowers are growing – to help scientists better understand the crucial relationships between pollinators, ecosystems, plant diversity, and human activity. On June 20, there will be an intro-duction to this program on a TFN Outing led by Bob Kortright (see p. 7). With populations of reptiles and amphibians dropping at an alarming rate and over 1500 species on the verge of extinction or already recently gone, Toronto Zoo administers two programs – Ontario Turtle Tally and Ontario FrogWatch –to monitor turtles, frogs and toads (see below).

PlantWatch began in Alberta in 1987 to track changes in flowering times of certain plants after it was noticed that some plants appeared to be flowering earlier and earlier each spring – some species now flower a month earlier than a century ago. PlantWatch is now part of Environment Canada’s NatureWatch, which also tracks climate change with a program called IceWatch. Ice events – the freeze and thaw dates of lakes and rivers – are easily recorded. Since climate change is not consistent across the country and because there are large gaps in the current monitoring network, citizen scientists are important in supplying much needed data from many more regions.

WormWatch is a nationwide earthworm census. Citizens report on the presence of worms in their soil in order to help understand soil ecology as well as to help figure out the question of whether Canadian earthworms were all killed in the last ice age and are now found due to introductions from Europe, or whether in fact some survived the ice age in certain regions.

The Christmas Bird Count (CBC) started in 1900 as a way to encourage people to switch from the tradition of shooting birds at Christmas to counting them instead. The first count involved 27 people in 25 sites across Canada and the USA. The most recent count tallied reports from over 2000 sites across the Americas. Analysis of the data collected from the last 40 years of the CBC was reported on in last month’s newsletter (TFN # 563, p. 16).

There are many other Citizen Science programs involving monitoring of birds such as the Great Back Yard Bird Count held over one weekend a year (the most recent with over 90,000 checklists submitted from 35 states and provinces) and Project FeederWatch which collects data on observations of birds that visit feeders in backyards and nature centers from November to April. These data help scientists track broadscale movements of winter bird populations and long-term trends in bird distribution and abundance. Many bird species or groups such as hawks and hummingbirds also have their own monitoring programs.

A new international system called eBird, launched in 2002 by the Cornell Lab of Ornithology and National Audubon Society, is amassing one of the largest bio-diversity data resources in existence. In 2006, partici-pants reported more than 4.3 million bird observations

across North America. These observations can be used to help monitor bird populations over time and across the landscape. As a participant, you can even use eBird to keep track of your own sightings and checklists! Anyone can access the data to create charts showing occurrence of particular species over time in particular places—across the whole of North America, just in Ontario, or even at one of six locations in Toronto!

One of the newest programs citizens can participate in is the Ontario Wasp Watchers Project -- watching for a native ground-nesting wasp that can indicate the presence of new infestations of the emerald ash borer (EAB) beetle before it becomes established as a serious pest. While the EAB is virtually undetectable, the native wasp that preys on EABs can be observed bringing them back to its underground burrow where they are stored as food for the wasps’ larvae.

CANADIAN LAKES LOON SURVEY

IF YOU’RE IN LOON COUNTRY IN THE SUMMER: • survey any Canadian lake at least once in June (for loon pairs), once in July (for newly hatched chicks) and once

in August (for the number of young that survive); • keep an eye out for other common waterbirds; • record your information and send it to Bird Studies Canada by mail or internet for analysis.

Your reports join hundreds others from across the country to support the conservation of loons and lakes. To register: 1-888-448-BIRD (2473) or www.bsc-eoc.org/cllsmain. • Loons are one of the oldest groups of birds living today, with a history of more than 50 million years. There are

five species of loons worldwide, four of which breed in Canada. The majority of the world’s Common Loons breed on Canadian lakes.

• Quiet “hoots” or “mews” are intimate chats among loons floating together. The wild “yodel,” with repeated triplets at the end, is a territorial call given by males. The familiar tremolo or “laughing” call is a distress call that loons give when alarmed or threatened. The cause could be another loon, a predator or a curious human. If loons give this call with you near, you may have approached a loon’s nest or chick too closely.

• At present, loon populations are stable but reproductive success is higher in western regions than in the east. Human activities have decreased the abundance and breeding range of Common Loons in North America in the last 150 years. Factors include acid rain, shoreline development, water level fluctuations, and water craft. Loons are also threatened by the deadly Type E botulism when they migrate through the Great Lakes. There are several US states where loons are threatened, endangered or no longer present.

If you’d like to become part of this extraordinary world-wide movement of citizen scientists, start by finding a program that fits your circumstances. Time commitment can vary from one to many hours per year, the place can be as close as your kitchen window or requiring travel some distance from home, and expertise can be at the beginner level of species recognition through to advanced.

For more information about these programs, google the project’s name. You can also phone Bird Studies Canada at 1-888-448-2473 for information and registration in many Canadian projects including Project FeederWatch, Canadian Lakes Loon Survey, eBird Canada, Marsh Monitoring Program, and Project NestWatch. The Toronto and Region Conservation Authority (416-661-6600 ext. 5574) also runs a monitoring program throughout Toronto and region for which they provide training for volunteers.

FROM THE ARCHIVES

From TFN Newsletter #212, April 1965. Wilderness Adventure, by Ronald G. Tozer It is 4:30 pm on a lazy July afternoon in Algonquin Park. As I get up from my chair in the museum's lab, my companion, a man some forty years older than I, remarks with reserved enthusiasm, “Should we go to Longspur Lake tonight?”

We gather cameras, binoculars, sheath knives, flashlight, hand axe and mosquito repellent. We strap the canoe on the car and drive to the beginning of the trail, which covers about three miles between the highway and Longspur Lake.

The sun is still quite high as we arrive and unstrap the canoe. I hoist the canoe onto my shoulders. My friend Russ, axe in hand, sets forth ahead of me on the trail, watching for our former blazes and re-marking those which have become dull.

The young maples grow profusely here in the deep shade of the climax forest. There is a pungent odour of decaying leaves, fungi and mosses. Before us is a low area which is open to the azure sky and supports a luxuriant growth of intricate hay-scented fern. The trail turns off to the left and up a ridge which has a huge rounded boulder, the size of your car, near its crest--a reminder that we are in the glacially-eroded Precambrian Shield. Nearby are several beech trees which have healed-over scratches, caused by bears' claws, on their smooth gray bark, and what look like large stick nests in the upper branches. Russ explains that the black bears climb these trees and pull the branches in to the centre to get the beechnuts, leaving these nest-like assemblages.

Shouldering the canoe again, we set off toward the lake. I listen for birds and can pick out an ovenbird, a veery, a raven, and far off the shrill cry of a broad-winged hawk. Another wet spot is traversed by way of a damp rotting log which is identified as hemlock, due to the reddish-orange bracket fungus (hemlock conk) growing on the side. Several dead balsams remain standing here, and in the quiet of the forest we are able to hear the rasping of bark beetles within these trees.

Another few steps forward and there is a great crashing of brush ahead of us. With haste we move on to discover a large grove of striped maple which has been heavily browsed and broken down. We have disturbed a moose (or maybe two) which has likely eaten here for several days. The moose can feed on these saplings which are too large for deer.

The sun lowering in the west urges us on once more. We have not gone much farther when a small bird flutters up from beside the path. Carefully we peer at the dead leaves, but it is a full minute before we discover the nest--the arched bower of the ovenbird with its set of eggs. We are pleased since this bird's nest is very difficult to find. Moving on now, the ground begins to slope toward the lake, and I hear the raucous cries of the young great blue herons in the nesting colony on the lake's two islands.

Arriving at the lake-edge, we pause to “breathe in” the

beauty of the area. The sun, with its deeply slanted rays, casts an ochreous hue upon the hemlocks, pines and spruces of the shore. A light wind is rippling the clear, cold waters of this northern lake, and now a loon gives its quavering call, to be answered immediately by another, and then still another until we can see four of these large divers. (Later we discovered that a pair was nesting on each of the islands).

The canoe is launched and we paddle out toward the islands, pausing when halfway there. The movement of our paddles ceases, and our senses become completely attuned to the evening scene. A Swainson's thrush repeats its escalating phrases from the top of a hemlock. Serpentine herons sit in tall pines, framed like ghostly sentinels against the western sky. Gently drifting, we are awed with this wilderness spectacle. Suddenly this somniferous interlude is interrupted by the far-off howls of wolves, just as the sun dips below the horizon. It is getting late. We must head back. Yet

WEATHER (THIS TIME LAST YEAR)

May 2008 May was relatively cool, especially in comparison to the warm April. Mean temperatures were about 1° to 1.5° below normal, with few extremes; warming up to 28° briefly later in the month but mostly below 20°. It was particularly cool the first couple of days and again the 18th to 21st. Monthly means downtown and at Pearson Airport were 12.7° and 11.9° respectively. Showers were frequent, but generally not too heavy; total precipitation was 68.8 mm at Pearson Airport and 53.7 mm downtown (actually below the normal 73.2 mm). Sunshine hours were close to normal. It was actually a rather pleasant month overall with unusually extended springtime conditions for Toronto (lasting from early April to the end of May) and no early start to summer. Flowering shrubs persisted most of the month.

June 2008 June brought changeable weather but ended up being slightly warmer and wetter than normal. The monthly mean temperature downtown was 20.0° and at Pearson it was 19.6°, about 1° above normal in both cases. The average warmth, however, was due to a distinct heat-wave from the 6th to 9th that peaked on the 9th with highs of 33.5° downtown and 34.1° at Pearson Airport. This ended in classic fashion with thunderstorms. After the heat wave, however, conditions were generally moderate, and downright cool from the 17th to19th with daytime temperatures in the teens and nighttime temperatures in the suburbs below 10°.

Frequent weather systems brought repeated showers and thunderstorms. None of these were particularly severe, although there were isolated flood incidents on the 23rd. It was the wettest June since 2000, with 99.2 mm of rain downtown and 110.4 mm at Pearson. With much of the rain being of convective origin, sunshine was down only slightly below normal—228.5 hours as compared to the long-term average of 254.0 hours.

July 2008 Near-normal temperatures and heavy rainfall characterized July. (Overall it felt a bit cool though humid.) Downtown had a mean temperature of 22.2°, which is exactly the long-term normal. Pearson’s 21.5° was only 0.1° above the long-term average. Summer heat was moderate this year, with Pearson reaching just 31.1° on a couple of days, and a total of five 30°+ days. Downtown never breached the 30° mark all month, peaking at 29.9° on the 16th.

The big news, however, was rainfall. Downtown had 121.1 mm of rain (normal is 67.5), which was the highest for July since 1996 (123.2 mm). But Pearson’s 193.2 mm was about 2.5 times the normal and made it the wettest July on record there, beating the former record set in 1980 (182.3 mm). Incredibly, there was no severe flooding of the kind recorded in the summers of 1986, 1996 and most recently in August 2005, though mild to moderate incidents were repeated. Rainfall was fairly well-distributed over the month with several heavy downpours, notably on the 8th, 19th to 20th, and 22nd to 23rd.

Also unusual was the co-occurrence of abundant sunshine with the rainfall—290.9 hours, almost 15 hours above the normal and close to what we received during the droughty July of 2007!

August 2008 August was a relatively cool month. It began with frequent thunderstorm activity carrying over from July due to an upper-level trough, but a trend toward drier (and somewhat warmer) weather ensued after mid-month. Downtown had a monthly mean temperature of 20.6°, which is 0.7° below normal, and Pearson Airport had a mean of 19.7°, also 0.7° below normal. It was the coolest August since 2004. Pearson failed to reach 30°, peaking at 29.4° on the 18th, but downtown reached 30.2° on that day. It was the lowest monthly maximum for August at Pearson since 1992.

Monthly rainfall was 81.4 mm downtown. This is only 1.5 mm above the 1971-2000 average, but because of the dry trend of recent Augusts, it was the highest for the month since 1999! Pearson’s total rainfall was 92.6 mm. This was enough to make the June to August (and May to August) period the wettest on record at Pearson Airport. 396.2 mm fell in the three-month meteorological summer period, beating 1986’s 335.9 mm. (May to August had 465.0 mm which beat 1986’s 411.1 mm). Downtown’s June to August total was 301.7 mm, the most since 1986 which had 355.7 mm.

A certain degree of global cooling has occurred since a warm spike in January 2007. The origin of this reverse trend (or its ultimate duration) is uncertain, but may have something to do with a strong La Niňa over 2007-2008, as well as unusually low solar activity. Arctic sea ice declined sharply this August, though, pointing towards the second lowest minimum on record after 2007.

FROM THE ARCHIVES continued from page 23 we will linger a time longer, as if to savour every possible moment with nature. We paddle back to the shore and place the canoe in a safe location. Starting back along the trail, we soon need our flashlight to find the blazes. As the trail passes near Jack Lake I hear the “Jug-o-rum” calls of bullfrogs, and a sound like stones being knocked together, emitted by mink frogs. By the time we reach the opening where the hay-scented fern grows, a large moon has come up to cause weird shadows among the tree trunks. The haunting query of

the barred owl—“Who cooks for you? Who cooks for you all?”—accompanies us when we near the highway. As we step on the pavement the midnight hour passes. We are both physically tired, but our spirits have been awakened by the occurrences of the past seven hours.

There is a pond beside the road, and a lone beaver swims across its moonlit surface. A speeding automobile flashes around a bend, flooding the scene with its headlights--the beaver slaps its tail--and our wilderness adventure is summarily ended.
