Today at 2 PM I had the Great Cormorant perched on a branch in the water right next to the gazebo. Many thanks to everyone who sent me excellent directions.
Then spent some time with the flock of redpolls that were feeding in the adjacent pumpkin field. I estimated at least 70 birds feeding on weeds near the middle of the field. I had several pale birds, but with scope views all had at least a couple dark undertail covert feathers. Except for one which I'd like to call a Hoary. I first noticed it as being very much paler than the others both above and below. On closer inspection with scope views it had all white undertail coverts, and was a bit bigger and "fluffier" than the others. I would feel better if I could have seen a smaller bill on the bird, but the bill seemed the same size as the others. Unfortunately the flock was moving around a lot so it was tough to keep on any one bird.
For others who come out to look for the Cormorant you might spend time combing through the redpoll flock to look for a Hoary.
