Data Sheet

Western red bats feed on a variety of insects, including moths, flies, cicadas, and ants. They hunt in open-space areas along forest edges and are commonly spotted feeding around street lights.  

Fun Fact: Western red bats are one of the few species of bat that regularly give birth to multiple pups–as many as four at a time! 

Appearance: Western red bats have fluffy, amber-colored fur and white patches on their shoulders. They can be distinguished from Eastern Red Bats by their smaller skulls, lack of white-tipped hairs on their back, and less furry tails. They can be distinguished from Southern Red Bats by their lighter pinkish face. 

Habitat: Western red bats roost almost exclusively in trees, where their coloring helps them blend among the leaves and branches. They prefer forests and riparian habitat near water, and roost in sycamore, cottonwood, velvet ash, elder, and mulberry trees.  

Western red batscan also be found in fruit and nut orchards, particularly in California’s Central Valley. Individuals generally roost alone, though can sometimes be spotted roosting in small clusters.  

Echolocation: Western red bats produce echolocation calls at pitches between 38 – 55 kHz, with maximum energy at about 42 kHz.  

Conservation Concerns: Conservation concerns include habitat loss and pesticide use. Western red bats are considered migratory in some regions and are among the species of bats killed by wind turbine facilities.
