Winter is not a great time for bird diversity in Yellowstone. We probably saw less than a dozen species of birds. Bald and Golden Eagles, American Robin, Barrow’s and Common Goldeneyes, Mallards, American Dipper, Clark’s Nutcracker, Mountain Chickadee, Common Raven, Black-billed Magpie. I think that’s all.
The goldeneyes were in small mixed groups, diving and feeding most of the time and easily seen from the road. The dippers were busy too, flying up and down the stream, calling to each other. Only once did I get a chance to make photos of them.
