Remember when Calvin insisted to his teacher that "Bats are birds"? (Correction - thanks, reader. I guess it was "Bats are bugs...". I was wrong again! That makes wrong twice in one week.)
New England is the home to around 7 species of bats, all nocturnal insectivores and most with some migratory habits.
Our most common bat is the Little Brown Bat (photo above) often found sleeping behind shutters or in crevices in sheds and attics during the summer and early fall. We had one who got into the house a few years ago. We managed to scoot him out a window. Wonderful - no, miraculous little critters, but worth keeping away from because they can carry rabies.
I noticed seeing very few bats around at twilight this year. I miss them dodging, diving, and ducking around in their bug-catching aerial antics. I checked it out. It turns out that there is a contagious bat disease in the Northeast. Whether this fungal infestation is the cause, or an effect of something else, is still not certain. It's a damn shame.
I hope their populations bounce back in my lifetime because these silent fluttering critters are one of the delights of the evening sky around here.
