Re: [Maine-birds] episodic photo quiz

Hi Stella,
You're right about that. I could easily second guess myself. I'll stay with COGO on the bird but this is where I'd probably fall back on "goldeneye species" if I were listing it.

My Best,
John

The two upper-left birds appear to have longer bills than the others and have distinct yellow tips. The bills on the two birds at right look a bit stubbier with mostly yellow bills that kind of diffuses into the black - not a sharp break. The lower left bird might be younger since it appears to have a darker eye and the yellow on the bill has not extended as much on the bill as the birds at right. Its yellow does appear to be going up the bill on the top and side.
