A little while ago I happened to glance out my window and spied two
crows on a nearby telephone line. One was preening the other on the top
of the head. The preenee sat still and tolerated it. Eventually the
preener stopped and sidled away a bit, whereupon the preenee looked at
it, and then the preener sidled back and did some more preening. I'm
not sure how long this had gone on before I noticed it, but it must've
lasted at least a minute while I was watching. Eventually the preener
flew down off the wire, the preen-ee following. Interesting. Had never
seen crows do this before.
