Correct me if I'm wrong, but I don't think a 2cy Bald Eagle could be could be classified as a juvenile. It should be referred to as an immature bird.Nice image of a juvenile (2cy) Bald Eagle 🙂
note a similar age GE still has an fairly darkish bill, more clearly defined white banded tail and light feathering on the nape

I disagree with you, sorry.Correct me if I'm wrong, but I don't think a 2cy Bald Eagle could be could be classified as a juvenile. It should be referred to as an immature bird.
This is the only point I was making really - the bird in the OP is still in the plumage attained when replacing the down feathers, so calling it a ‘juvenile’, even though it is in it’s second calendar year, is not just commonly but technically correct....the usage that a bird in its first fully feathered plumage is a juvenile for how ever long it stays in that plumage is commonly considered correct.
Well I know Americans have different ways of labelling plumages but to say a 2cy Bald Eagle in juvenile plumage cannot be regarded as a ‘juvenile’ makes absolutely no sense from an ornithological perspective - at least in how we approach moult definitions etc outside of America.I have to agree with this. A second year bird should be called immature not juvenile.
