Brown Thrasher falling off feeder?

Well that may be what it looks like but he was just flying down to the ground to feed. I have seen a thrasher several mornings lately. The thrasher attacks the sunflower seeds like a woodpecker Perhaps he breaks the seed open by savagely thrusting at it. Other birds seem to crack the seeds in their beaks. Usually I only have a brief glimpse of a brown thrasher once or twice a year but this year at least one seems to have decided my feeder is a good place to fill up. The thrasher rarely actually goes onto the feeder as happened here. There is little room and no room to wind up for a big peck.
