Leat-Nosed Fruit Bat 
hind feet, in some dark building, cave, or hollow tree. In 
winter many bats hibernate in similar quarters, but there is also 
a southward migration of certain species, like that of the birds. 
The voice of bats is exceedingly high-pitched and squeaking, 
and is most often heard when they have been captured or dis- 
turbed during retirement in the day-time. 
In such of our eastern bats as have been studied during the 
breeding season, two young seem to be the regular number in 
each litter, and they are usually born in July. 
Our American bats represent three families, as follows : 
I. Leaf-nosed Bats. Family Phyllostomatide. Size large, tail usually 
wanting, a curious leaf-like appendage on the end of the nose. 
Il. Free-tatled Bats. Family Noctilionide. Size rather small, 
tail present but the terminal half free from the interfemoral 
membrane, projecting beyond it. No appendage on the nose. 
Ill. Common Bats. Family Vespertilionide. Similar to the last 
but with the interfemoral membrane reaching to the tip of 
the tail. 
LEAF-NOSED BATS 
(Family Phyllostomatide) 
Leaf-Nosed Fruit Bat 
Artibeus perspicillatus (Linnzus) 
Length. 2.75 inches. 
Description. Head broad and thick, nose-leaf, consisting of a 
high-pointed central lobe and two smaller lateral ones 
separated from the middle one by the nostrils. No tail. 
Interfemoral membrane reaching to the ankles, but much 
hollowed out in the middle. Colour, deep brown or gray, 
with more or less ashy tips to the fur. 
Range. Tropical America, north of Key West, Florida. 
This is only a rare straggler to our southernmost coast, and 
is the only representative of the leaf-nosed or vampire bats that 
we have in the eastern United States, though one occurs in 
California and another in Texas.
