TheBirdSpot 20 Posted December 8, 2019 Hello! I keep seeing gulls flying about my house near Boise, Idaho and I'd like to add them to my yard list but I don't know my gulls... these aren't the best photos but can anyone definitively tell what kind of gulls these are? Thanks for your help! Quote Share this post Link to post Share on other sites
AlexHenry 250 Posted December 9, 2019 I suggest you start with California and Ring-billed and try to narrow down from there 1 Quote Share this post Link to post Share on other sites
Melierax 660 Posted December 9, 2019 Giss says Ring-billed to me. I believe Californias have a distinct hood this time of year, and the black on the wings seems too little for California. 2 Quote Share this post Link to post Share on other sites
akiley 1,053 Posted December 9, 2019 I agree with Ring-billed. The bottom bird in the second photo shows a large white mirror (spot) on P10 (the outermost primary), and no discernable window on P9. This is good for Ringer. Adult Cali Gulls have a decent sized mirror on P9. 2 Quote Share this post Link to post Share on other sites
akiley 1,053 Posted December 9, 2019 The top bird in the 2nd photo appears to be a 2nd cycle bird, with almost no white in the wing, and size compared to the bird below it make it a Ringer also. 1 Quote Share this post Link to post Share on other sites
