The portico light had been left on, and after a while I noticed that bats had begun swooping in to catch the insects that swarmed around it. Eva and I went to the door to watch. Just as we got there, a bat flew in above us and didn’t go back out. I opened the door and looked up. He had climbed into the crack between the end of the roof and the side of the house, and had begun grooming himself. With the aid of a flashlight, this turned into quite an engrossing spectacle.
The bat – a little brown myotis, presumably a solitary male – kept his face turned mostly away from us, so that what we saw most often looked like a big-eared mouse chewing on a tiny umbrella. Only when he worked on the surface of an open wing did we get a look at his face, dimly visible through the thin membrane of skin.
The contrast between the smooth wing and the deeply wrinkled, pushed-in face seemed to suggest some elemental truth about the night, and about the sort of consciousness one must evolve to fully inhabit it. I mean, one can easily follow custom and read into a bat’s face the stamp of evil, or an eldritch wisdom. But nothing of that sort came to mind; only now, in retrospect, do judgements like these suggest themselves. We felt, I think, only a simple awe.
We watched so long, Eva started to complain of neck cramps, and both my arms got tired from holding the flashlight in turn. He spent most of his time on the wings, with only a few nibbles at his abdomen. Is this something that bats have to do every few hours to remain flight-worthy? Bat Conservation International’s website says only that
In addition to day roosts in tree cavities and crevices, little brown myotis seem quite dependent upon roosts which provide safe havens from predators that are close to foraging grounds.
So possibly the screech owl that we heard calling intermittently had been too close for comfort.
When the bat finished grooming, he turned his listening face full on me for a few seconds, then, rather than flying out the way he came, scuttled up feet first through a crack in the tiles and disappeared. It was only then that I thought to wonder if the flashlight had hurt his eyes.
