That’s what I figured. The double-crested are bulkier than the Brandt’s, but not a lot. They have no blue in non-breeding plumage. If you get to the coast and see a really slender cormorant with a white mark on the rear flank and a skinny bill, that would be a Pelagic Cormorant. And you might find a red-faced with study and careful observation.

Mostly double-crested around here, though the National Audubon Society book I have shows both in the area. I’ll keep an eye out for the shapes of the neck and if I can find any blue colorations.
All the best.
