Hairy-legged vampire bat
The hairy-legged vampire bat (Diphylla ecaudata) is one of three extant species of vampire bats. It mainly feeds on the blood of birds. This vampire bat lives mainly in tropical and subtropical forestlands of South America, Central America, and southern Mexico. It is the sole member of the genus Diphylla.
It generally rests during the daylight, with fewer than twelve other bats in a cave, although a cave was once found with thirty-five bats. It also shares its food via regurgitation, mouth to mouth.
This bat has good eyesight, but poor echolocation. It is often found in caves with the common vampire bat (Desmodus rotundus), but it is a solitary bat and does not form groups like Desmodus. There are no lingual grooves under the tongue as in Desmodus and Diaemus (the white-winged vampire bat), but it does have a groove along the roof of the mouth which may serve as a "blood gutter".
The two recognized subspecies are:
- D. e. centralis is found from western Panama to Mexico. A single specimen was taken in an abandoned railroad tunnel near Comstock, Val Verde County, Texas, in 1967, well outside the taxon's recognized range.
- D. e. ecaudata is found from Brazil and eastern Peru to eastern Panama.
