Urban Species #114 Big brown bat Eptesicus fuscus

The most urban of all North American bats, the big brown bat roosts almost exclusively in man-made structures. A few colonies have been found in hollow trees or caves, but for the most part, these animals prefer attics, barns, and belfries. As they are among the most cold-tolerant of bats, they will roost in more open places, such as under bridges and in chimneys. They are the first bats seen awake in late winter, and the most commonly seen bats in our area. They feed on insects over still water and open areas, and are also frequently observed taking advantage of the bug-attracting properties of streetlights.

Perhaps the most famous urban bats are those that make up the colony of Mexican free-tailed bats (Tadarida brasiensis) in Austin. Someday I dearly wish to see the spectacle of more than a million bats (the largest urban colony in the world) stream out from underneath the Congress Avenue bridge.

Nice post, and I'm totally impressed that you managed to capture them in flight.

But where did you find one during the day? Did you just happen across that little fellow? I've never seen one in the day; that's amazing.

cottonmanifesto came across that sleeping bat on her way to work. It was on a wall in the Longwood medical area.
