Tony Leukering Posted February 15, 2021 Share Posted February 15, 2021 Note the large, blocky heads on the Commons as opposed to the petite heads on the Red-throateds, among many other shape and plumage differences. 1 Quote Link to comment Share on other sites More sharing options...

Jefferson Shank Posted February 15, 2021 Share Posted February 15, 2021 (edited) Common Loon Red-throated Loon Common Loon Pacific Loon - note that there is a defined line between the black and the white, and also there is a partial collar jutting out which nonbreeding Pacific's have.

Hasan Posted February 15, 2021 Share Posted February 15, 2021 4 is not a Pacific Loon. It's a Common- notice the massive bill. Structurally, Pacific is very similar to Red-throated. 2 1 Quote Link to comment Share on other sites More sharing options...

Good point. the coloring fits better for Pacific, but the bill rules Pacific out. 1 Quote Link to comment Share on other sites More sharing options...

Pacific Loons never have a Jagged Collar, that's Common Loons. 1 Quote Link to comment Share on other sites More sharing options...
Jefferson Shank Posted February 16, 2021 Share Posted February 16, 2021 Pacific Loons never have a Jagged Collar, that's Common Loons. I was talking about this part of the collar(see photo). This is a Pacific Loon from Macaulay Library. 1 Quote Link to comment Share on other sites More sharing options...
blackburnian Posted February 16, 2021 Share Posted February 16, 2021 In addition to the collar being wrong and not cleanly contrasting, the bill is far too hefty for Pacific for 4. Agree with Common. 1 Quote Link to comment Share on other sites More sharing options...
