LISTERS CORNER: SNOWY PLOVER Alan Contreras A few coastal points and a scattering of alkali flats in Eastern Oregon are the best spots to find Snowy Plovers. The best coastal spots are areas usually inaccessible to conventional vehicles. The Bayocean Spit at Tillamook i s one such place, and i t can be reached by driving west and north- west from Tillamook toward Cape Meares. The spit is over 3 miles long, providing good Snowy Plover habitat in the dry sand on the ocean side. Most of it must be walked. The low dunes and beaches south of the entrance to Yaquina Bay at Newport, and any similar areas between Florence and Yachats are good spots." The sand and beaches at the mouth of the Siltcoos River between Florence and Reedsport. Further south, one area of Snowy concen- tration, as much as Snowy's can be said to congregate, i s a section of dry beach and dunes about 1.3. miles from the jetty on Coos Bay's north spit. This area is accessible only by.4-wheel drive, on foot, or by boat. It can be reached by driving over the Horsfall Beach Dike from Hwy. lol, then past the Menasha and Roseburg plants until sand covers the road. Euchre Creek mouth near Gold Beach is reported to sustain a small population. In Eastern Oregon, where the birds are often more accessible, the best locations are on the akali flats around the northern end of Summer Lake along Lint Canal Rd, where there is a sizable nesting population; and in the same type habitat in the "00" region at Malheur where they also nest.

TAXONOMIC NOTES - LB. McQueen

We cannot be sure of the race of the Red-shouldered Hawk which stayed during a few weeks i n January along 11th Avenue at Fern Ridge, but there i s no reason to suspect any other than the Ca l i f o r n i a race, elegans.

Buteo lineatus i s separated into fi v e races:

subspecies lineatus - the nominate, "Northern" red-shouldered - extends as far west as Nebraska and Kansas.

a l l e n i - the Flo r i d a race - ranges from South Carolina through Arkansas and Oklahoma,throughout Florida.

extimus - the so-called " I n s u l a r " hawk - i s the Everglades race of southern Florida.

texanus - i s confined to Coastal Texas, south to Mexico City.

elegans - the "Red-bellied Hawk" - resides mainly i n the Sacramento and San Joaquin Valleys to lower Cal i f o r n i a .

The southern forms are apparently non-migratory. There may be an occasional d r i f t e r into southern Oregon, but actual records are hard to find. Gabrielson and Jewett l i s t i t hypothetically, casting doubt on Johnson's reports at the north end of the Willamette Valley (1880) and Bendire's alleged egg record from Camp Harney (1892). The species does not appear on Bertrand and Scott's c h e c k l i s t of the birds of Oregon. I am personally unaware of any authenticated records for Oregon.

This b i r d looked different than any red-shouldered that I remember i n the east, and t h i s difference i s not accounted for by any r a c i a l p e c u l i a r i t i e s . Observers of this p a r t i c u l a r hawk noticed that aside from the diagnostic l i g h t patch i n the primaries which showed best i n f l i g h t , there was nothing p a r t i c u l a r l y outstanding about i t . The markings which are supposed to be so con­spicuous at a reasonable range - the reddish "shoulder" patches, the black and white barred wings and t a i l , and the reddish-barred underparts, with a rather s o l i d rufous breast - were very d i f f i c u l t to see.

NEST RECORD 1977

The North American Nest Record Card Program.

For a number of years now, the Laboratory of Ornith­ology at Cornell University has been gathering data on the nesting cycle of a l l species of birds from a l l over the country. Many thousands of cards have been sent i n through the years. The sample reproduced here indicates the kind of information needed. You'll note that there are spaces for 10 entries and, as you can surmise, re­cords that come close to providing 10 bit s of informa­tion about a p a r t i c u l a r nest are more useful than those with only one. That i s n ' t to say that the l a t t e r are not helpful, however. I f you happen to discover a nest and are unable to r e v i s i t (or perhaps the birds are ready to leave that day) then by a l l means submit the information. When added to other information, a picture may emerge. Please note also, that negative reports are as useful as positive ones. That i s , i t ' s important to know i f a nest was broken up the day after you discover­ed i t being b u i l t . In other words, record everything and anything you can, about any nest you find, at any stage of i t s cycle, on any species, anywhere. ( I s that i n c l u s i v e enough?). The undersigned has s p e c i a l i n t e r ­est i n breeding d e t a i l s on birds and can provide record sheets that reproduce the data cards as shown. The ad­vantage of the sheet over the card i s that a map of nest location can be drawn on the back and additional i n t e r ­esting observational notes can be recorded there also. The d e t a i l s are copied onto the Cornell cards and sent along to them.

I f you want to be prepared on any f i e l d t r i p during the breeding season - February through July or l a t e r -put i n your request for a supply of the forms.

PINTAIL, GREEN-WINGED TEAL and CAaR'ASBACK w i n t e r here, and the count o f w i n t e r i n g GADWALL has reached 2,000 ! EUROPEAN WIGEON are present i n some years, and small numbers of SHOVELEF, REDHEAD and RUDDY DUCK are u s u a l l y around. PEREGRINE FALCON and MERLIN have hunted here, and MARSH HAWK and SHORT-EARED CWI. are o f t e n o-esent. Thousands of shcrebirds migrate through and w i n t e r on the f l a t s and adjacent a i r p o r t g~ass and runways. GREATER YEIJOWI,EGS, LEAST and WSST1RN SANDPIPERS are common, as are SLACK-BELTIED PLOVERS. RUDDY and BLACK TURNSTONES are o f t e n seen, as are both DOWTTCHEES. BAIRD'S SAND­PIPER, SEMIPALMATED SANDPIPER. AM. GOLDEN PLOVER and RED KNOT have been recorded, KNOTS more f r e a u e n t l y i n recent years. MARBLED GOOWITS w i n t e r here i n small num­bers, and up t o 80 have been present during f a l l mig­r a t i o n peaks.

HARLEQUIN DUCKS have also been found i n the boat basin area. A BLACK-THROATED SPARROW has been found on the grounds of the nearby Oregon I n s t i t u t e o f M a r r ine Biology, as have PALM WARBLERS i n October.

SEMI-WILD TURKEYS NEAR ROSEBURG

While the Wild Turkey i s not native to Oregon, sev­eral "successful 8 releases of introduced birds have occurred i n Oregon. In the early 1950's private indi­viduals in Douglas County released Wild Turkeys east of Roseburg. I observed several of these birds on November 27,1976 and on February 20,1977. These turkeys have the field markings of Wild Turkeys - a slim body and a light brown band at the tip of the t a i l . I n February the two males were observed displaying to six females in the area indicated on the accompanying map. They are reported to roost in the cemetery illustrated below. The circled numbers indicate locations where this flock was observed on the two respective dates.

This flock and a larger flock of 30 to 40 Wild Turkeys which i s reported to l i v e in the oak-covered h i l l s east of Highway 138,have maintained a f a i r l y stable population throughout the l a s t 20-25 years according to Bert Meloy, a resident of the area. Mr. T o fiuoc Meloy stated that lack of winter food, resulting from spoiling during the norm­a l l y wet f a l l , winter and spring, and predation of eggs and young by dogs, cats, skunks, and raccoons, trim the population. Only supplemental feeding from local residents keeps the Wild Turkeys alive during the winter. This depend­ence upon human feeding Jeopardizes their status as beiag; -truely wild.
