About the Townsend's Big-eared Bat

Townsend's big-eared bat (Corynorhinus townsendii) is a species of vesper bat. Townsend's big-eared bat is a medium-sized bat (7–12 g) with extremely long, flexible ears, and small yet noticeable lumps on each side of the snout. Its total length is around 10 cm (4 in.), its tail being around 5 cm (2 in) and its wingspan is about 28 cm (11 in).

The dental formula of Corynorhinus townsendii is 2.1.2.3.3.1.3.3. × 2 = 36 C. townsendii can be found in Canada, Mexico, and United States. Specifically, its main range is from southern British Columbia, down the Pacific Coast and into the Great Plains as well as Central Mexico. It also has two isolated populations in central and eastern parts of the United States respectively.

A notable colony of Townsend's is the colony currently residing on Santa Cruz Island, the area the species was originally described from and the only colony known in the Channel Islands. Originally there was a Santa Cruz colony of 300 bats known to reside in a historic ranch house, which was displaced in 1974 when the building was removed. Now there is a colony known to have resided in the Scorpion adobe building from before 1991 onwards. This... Wikipedia →
