Silver- Haired Bat

What is a bat?

Bats are the only mammals that fly. They have furry bodies and thin, leathery wings. Bats hang upside down when they are resting. Bats sleep during the day and come out at night to feed. Bats find their way by making high-pitched squeaks and clicks. The echoes of these noises are picked up by sensitive ears and used to guide them around.

Colour

Unlike most bats, the silver-haired bat is easily distinguishable. It has a deep chocolate brown colour with a white frosting on its back and abdomen.

Habitat

The silver-haired bat is associated with forest and grassland habitats and is often abundant in old-growth forests.

What do they eat?

Silver-haired bats eat a variety of arthropods. They consume flies, midges, leafhopers, moths,. mosquitoes, beetles, true bugs, and ants.

How do bats use Sonar

In the 1930s scientists discovered that bats use a kind of natural sonar that allows them to "see" with their ears. This amazing system is called Echolocation. Echolocation is similar to sonar. Bats emit pulses of high frequency sound waves that reflect (echo) back to them. In this way bats maneuver around objects in their path and are able to target tiny flying insects.

History of Bats

Almost 1/4 of all mammal species are bats (1,116 species) ranging in size from the 2 gram Bumblebee Bat to the 750 gram flying foxes. As a group they are poorly understood and often feared. Common misconceptions about bats contribute to the fear. Bats do not get tangled in hair, they do not all carry rabies, they do not all suck blood, and they are not blind. They are amazing creatures. They are nocturnal (active at night) and use a sophisticated ultrasonic detection system known as echolocation. They play an important role in many ecosystems as seed dispersers, pollinators and controllers of night-flying insects

Bat Predators

Numerous anecdotal observations have revealed a wide range of predators for bats. Raptors and owls approach bats and often catch them in flight. Opossums and snakes may wait close to roost sites or attack fruit-eating bats when they approach trees loaded with ripe fruits. Presumably to lessen the risk of being caught by predators such as owls, some bats are known to drastically reduce their activity level during bright nights around full moon.

How do Silver Haired Bats find food.

In this way, bats are able to comfortably move around at night, avoiding predators, maneuvering around obstacles, locating their food, and capturing insects in total darkness (That is impressive alright).

Echolocation

Echolocation:

It was found out in the 193o's that bats use high pitched sounds like a natural sonar to locate food and navigate When these sounds bounce off of objects bats are capable of listening to these echoes and are able to judge distance,movement and size of all objects in their path.

Pesticide

Pesticide is a substance or a mixture of substances used to kill a pest. Pesticide is a chemical substance used against any pests. Pests include plants,insects,weeds,mamals,fish or any kind of animals.

How big are Silver Haired Bats?

Silver-haired bats are about the size of your

palm.And wingspan about the size of your

hand.
