Pallas' Mastiff Bat

Pallas' Mastiff Bat

Pallas' mastiff bat, also known as the velvety free-tailed bat, has reddish brown to black fur and a musky odor. Found in subtropical forests, this species' range extends though Central and South America. This bat commonly roosts in manmade structures as well as tree hollows, palm fronds, rock crevices, and caves. Though they are native to Cuba, it is believed Pallas' mastiff bat was introduced to the Florida Keys as part of a mosquito control plan in 1929. Common food items for this bat include flies, beetles, ants, and moths.
