Thursday, July 13, 2017 · In the SBA (Significant Bat Area) of Central Texas

Northern yellow female pup on left and a Southern yellow male pup on the right.
When full grown, the Northern yellow bat will be twice the size of the Southern.
When they are pups, the size is the same, but the color and texture of the fur distinguishes them.
The Northerns are sleeker and more blonde-colored.  The Southerns are woolier and more olive-colored.
