Reported in The Sibley Field Guide to Birds as “Very Rare” is a Black-headed Gull. We managed to see two separate flocks of these birds on our trip across Alberta and Saskatchewan. This is a lifer for me!
Dianne, good question! The predominant reason is the fact that these guys have red bill and feet and legs, where the Bonipart has black. The Bonipart is also a bit bigger.
WOW! What a treat it is to get another lifer.

Ruth, thanks! Yes, it sure is!

A lifer! And a rare bird, at that. Congratulations.

Pat, thanks so much! I was very happy to see them!

Oh! What makes this different than a Bonaparte’s Gull?

Dianne, of course I should have spelt it Bonaparte!
