YELLOW BAT 



number ot young, (often four), but differs in its greater size, 

 gray instead of reddish color, later appearance in the evening, 

 and generally higher course of flight. This Bat is not common 

 anywhere and does not take to the air until the twilight is 

 nearly past. It is one of the least known of our widely rang- 

 ing Bats. A specimen in the hand can not be mistaken for 

 any other species and it is easily the most handsome North 

 American Bat. 



There are many observations on record to show that the 

 species of Nycteris migrate with the coming of the autumn 

 frosts.
