Little Brown Bat 
corner of the sash. I find that they habitually sleep in the barn 
in the narrow space between the ridge pole and the roof boards, 
though whether their numbers vary there from day to day as they 
do in the window, I am unable to ascertain. I have an idea that 
they also spend the winter there, for they are said usually to choose 
some such place to hibernate in. 
As twilight comes on, the bats in the window begin to grow 
somewhat more restless, scrambling down from time to time to 
peer out betveen the slats as if to pass judgment on the weather. 
Then suddenly one of them launches out and downward at an 
angle toward the earth for a few yards, then sweeps up and away 
among the tree tops. Another follows, and then two or three to- 
gether, till in very short time the blinds are empty; but outside 
in the darkness the bats are zigzagging about in pursuit of their 
supper. 
Large Brown Bat 
Vespertilio fuscus Beauvois 
Called also Carolina Bat. 
Length. 4.60 inches. Expanse of wings. 12 inches. 
Description. Flight membranes naked except the base of the in- 
terfemoral membrane. Fur silky, dark brown, rather lighter 
below. 
Range. Gulf Coast north to Maine and Ontario. One of the com- 
monest bats in the lowlands of the Middle States. 
This is one of the commonest bats through the southern 
United States as far north as the upper limits of the Carolinian 
faunal belt, through southeastern Pennsylvania, southern New 
York and the Connecticut Valley. 
In the Hudson Valley, Dr. A. K. Fisher says: ‘‘ They are the last 
to make their appearance in the evening. In fact, when it gets 
so dark that objects are blended in one uncertain mass, and the 
bat hunter finds that he is unable to shoot with any precision, 
the Carolina bats make their appearance as mere dark shadows, 
flitting here and there while busily engaged in catching insects.
