Young Blue Jay with Tail and Wing Feathers Spread - August 30, 2013
One theory as to why Blue Jays and other wild birds do this is that they are are controlling feather parasites. This youngster remained in this position for about 2 minutes and then flew over to a feeder to eat sunflower seeds.

on Sep 01I have seen robins doing this in the grass several times but that is the only bird I've seen until this one.
