smittyone@cox.net Posted September 9, 2021 Share Posted September 9, 2021 I presume these two gulls are young Ring-billed Gulls because they were the same size as the rest of the flock of adult Ring-billed Gulls. There were non-breeding Franklin's gulls (much smaller) and a pair of Forster's Terns mixed in as well. Is the 1st pic (the one on the grass) a First Summer bird, and the 2nd pic a Second Summer bird? They were seen yesterday in Council Bluffs, Iowa.

Aidan B Posted September 9, 2021 Share Posted September 9, 2021 I'm pretty sure you've aged them correctly 1 Quote Link to comment Share on other sites More sharing options...
Quiscalus quiscula Posted September 9, 2021 Share Posted September 9, 2021 I think the first is a First Winter bird, or at least molting into it, and the second bird looks like it's almost an adult, or a nonbreeding adult with more extensive streaking.
