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.

If a bat’s hands are its wings (and they are!), then these pups are in good hands.
Love the way the mum embraces the pups in these photos.

We keep all the bat families ID’d with varying types of marks, so we can track the 30 juveniles we have flying. This way we can make sure all pups are reunited with their mums in the morning to nurse through the day.

This pup is from the red bat family with yellow on their ears.  Even though he flies well, he returns to his mum to nurse during the day.  His two youngest brothers still do not fly, but soon all will be developing their hunting and drinking skills.  Once they are all up to speed we’ll release each family together, at least that’s our preference.  Sometimes the oldest and the mums get antsy and they let us know they are not willing to wait on the youngsters.  We monitor them closely and release as they let us know they are ready.
