[Tweeters] Twisted Bushtits

As I was carrying out a warmed hummingbird feeder to swap for the one that
was about to freeze, the twice-hourly swarm of bushtits showed up on the
suet and peanut feeders, so I stood 2-3 feet away to watch them for a
couple of minutes. I realized something I'd never noticed before: many of
the Bushtits had curved tail feathers. Some were perfectly straight, but
several others had a fairly obvious bend to the right, and at least one had
a slight bend to the left. I suppose these warps get into the feathers
when they are crowded into a roost?
