This young one has mastered the long, scritchy song. See his puffed throat and slightly opened bill? They often sing when I'm too close to the feeder for their comfort and they feel they have to do something, so land nearby and sing a song of anger or frustration or who knows what.
Adults do that too. I didn't realize they look kind of shabby this time of year, at least their belly feathers. The gorgets remain pretty decent.
Winding up to take flight. Reminds me of Totoro.
