Was the wind blowing causing the bird feeder to move? (what was your shutter speed?) Maybe a software glitch with your camera or more probabal post software with a super large crop-in for the missing pixels.
There was very little wind. These feeders are surrounded by trees and vegetation so they are in a protected spot. My shutter speed was 2500 (catching some BIF) and no crop. That is the full picture. I was in DX mode.
