General Notes

Bonaparte's is a tree nesting gull, choosing a coniferous forest close to muskeg or lakes, and usually placing the nest 4-6 meters above ground. 

Formerly in the genus Larus, this species was moved into the newly created genus Chroicocephalus in 2008 on the basis of genetic differences determined from the study of mitochondrial DNA.
