Bird-Boys 48 Posted June 25 Seen at Oso Flaco, CA on 6/20/19. I was thinking either common or forster's tern. Any ideas? Quote Share this post Link to post Share on other sites
geoffclarke 82 Posted June 26 I would go with Common Tern rather than Forster's, but am curious what experts say. I am going by bill color, head pattern, tail length, but I'm not sure if those marks are reliable. 1 Quote Share this post Link to post Share on other sites
Creeker 148 Posted June 27 Belly looks whiter than the mantle to me, especially in the last pic. Makes me think Forster's. But to say for sure you need a bit better pic. I am swayed partially by living in Ca., Common Terns are not that common, but Forster's are. 1 1 Quote Share this post Link to post Share on other sites
