BAT SPECIES IN SASK.
There are 18 species of bats in Canada. Some have a very broad range, while others are only found in eastern or western Canada. All species of bats in Canada feed solely on insects. Some species are non-migratory, whereas others are migratory.
Scroll down to see all eight different varities of bats that can be found in Saskatchewan.
Big Brown Bat
This is one of the largest species of bats present in Canada. Its coat is composed of many colours. It is typically dark brown on its back and paler on its underside. Its fur has an oily sheen. The face, ears, wings and tail are black and have a leathery appearance. Its ears and tragus are rounded. compared to other species, the big brown bat can tolerate hibernating in roosts that are colder, drier and more exposed to air currents.
Little Brown Bat
Its fur colour is variable, ranging from olive brown to almost black. Its fur is shiny and is darker at the base than it is at the tip. You can identify this bat by its several long hairs that extend from its feet to its claws, or sometimes even further. This bat has a rounded tragus that extends half the length of the ear. This differs from the tragus of the northern long-eared myotis, which has longer ears and a tragus that is longer, thinner and pointier at the tip.
Western Small-Footed Bat
Its fur is a yellowish-brown colour with a paler underside. As its common name indicates, its feet are unusually small, being about half the length of the tibia. The ears are relatively long and the tragus is long and narrow. Its face and ears as well as its wing and tail membranes are black, which creates a contrast with its pale underside fur. This last characteristic allows it to be distinguished from the closely related California myotis.
Long-Eared Bat
The long-eared myotis's name comes from its long ears, the longest of any North American myotis species. This species can easily be confused with Myotis keenii. Its fur is dull and is pale brown to straw-coloured. The subspecies M. evotis pacificus that lives on the west coast has a darker fur. Its ears and the membranes of its wings and tail are black. The tragus is long and slender.
Northern Long-Eared Myotis
The fur on the back and ears of the northern long-eared bat is dark brown, while its underside is a paler yellow-brown colour. This bat has very long ears with a thin tragus that is pointy at the tip which distinguishes it from the little brown bat, who has a tragus that is short and rounded. The wings and tail of this species are larger than those of the majority of the members of the genus Myotis.
Hoary Bat
This is the largest species of bat in Canada. They have a light-brown coat with individual hairs that are ash-coloured at their tips. The hair around the face and chin is yellow, which can help distinguish them from other species. Hoary bats’ ears are short and rounded with a well-defined black line bordering them. The tragus is short, round and wide. The back of the uropatagium and feet are covered with dense hair.
Red Bat
Males have a red-orange coloured coat, whereas the coat of females is a mixture of yellow and maroon. Fur colour is a distinguishing characteristic of this species. The hair on its back, chest, and shoulders is white and there is a white patch under its chin. The eastern red bat's uropatagium is covered with thick fur. Their ears are hairy, round, and lack a black border. The red bat has long, thin wings that are covered with hairs that extend all the way to the wrist.
Silver-Haired Bat
This species's fur on its back is black or dark brown with silver tips. The coat covers the upper portion of the wings and about a third of the uropatagium. The ears are almost as long as they are wide. They are black at the base with a pink interior. The tragus is short, straight and rounded at the end. The silver-haired bats' slow flight distinguishes them from other species.
