That the red bat sometimes winters in caves in 

 Pennsylvania has been proved by the fact that the 

 author found hundreds of them in Delaney's Cave, 

 near Fairchance, Fayette County, during the month of 

 February. 



The Little Brown Bat 



Myotis lucifugus lucifugus 



The little brown bat is similar in coloration to its 

 larger cousin, but its ears and tail are proportionately 

 longer, although its general size is considerably 

 smaller, being only three and one-half inches in length. 

 This species is probably the commonest bat in the 

 State and the author has seen thousands of little 

 brown bats hibernating in Bear Cave in Westmore- 

 land County. While it is said by some writers to ven- 

 ture forth in mild weather, the writer has observed 

 their hibernating habits for a period of five years and 

 in no case did the creature show signs of activity until 

 late in the Spring. 



In some cases the bats arranged themselves on the 

 walls of the cave in a compact formation for the win- 

 ter's sleep. At the same time, others formed "clusters" 

 on the ceilings. Albinos were found among them from 

 time to time. 



The little brown bat has a wing spread of nine 

 inches and its tail is almost one-third the body length. 

 There are usually two young in a litter and these re- 

 main attached to the mother's breasts until they are old 

 enough to hang up in some secluded spot while the 

 parent searches for food. This creature may be seen 

 on summer evenings in the low lying rural sections of 

 the State.
