This afternoon, I took a bicycle trip to Delta Park East in search of the reported Lesser Black-backed Gull from two days ago. I got there at about 4:10 pm, and there wasn't a gull to be found anywhere in the complex.
I packed it in, and road over to nearby Heron Lakes Golf Club in search of gulls. On my way to the parking lot, I stirred up approximately 100 European Starlings that were feeding on worms in the grass. As I watched them fly in unison, I noticed one individual that had a well defined white rump. I never did see it land, and lost it a few moments later as the flock spooked and dispersed to various trees some distance away. It was hard to get a good look at the entire bird as the flock was twisting in flight in tight formation, but the white rump was glaring at certain angles.
My question is, has anyone noticed this type of pigment loss on a Starling before? I want to say I've seen an odd Starling or two with haphazard white coloration throughout, but nothing as clean cut as the white rump I saw on this bird.
I can't help but scratch my head a little over this observation, especially when birds like the one in the link below are found in recent times:
