Color: Males are bright orange-brown to reddish-brown; Greg Sievert
females have reddish-brown fur with white hair tips.

Preferred Daytime Roost: Roosts in trees.
Evening Flight Time: Before dark.
Feeding/Flying Behavior: Commonly seen flying below
streetlights and along edges of tree-covered areas.

In Hand: Look at the red color to distinguish from the seminole
