Myotis californicus

The California myotis (Myotis californicus) is a species of vesper bat. It is found in British Columbia in Canada, Guatemala, Mexico, and in the western United States, including California. The California myotis is a small (70-94mm and 3.3-5.4g) bat with pale, dull fur. Ears are of medium (12-15mm) size, with a narrow, pointed Tragus (ear). They have an obviously keeled calcar and very small feet (5-7mm), smaller even than the feet of the western small-footed myotis for which they are easily confused. Other distinguishing features include the slightly lighter face mask and shorter appearance of the California myotis' tail. While their tails are the same length, the small-footed myotis' tail extends 2-3mm after the connecting membrane (Uropatagia) which makes it appear longer. The Dental formula for M. californicus is 2.1.3.33.1.3.3 × 2 = 38 During the day, the California myotis will roost in the bark of trees, rock crevices or buildings. They tend to emerge just after dusk and just before dawn to forage. Diet includes moths, flies and most other flying insects. Flight is slow and highly maneuverable which assists in prey capture.
