Nesting Bonaparte's Gull

The Bonaparte's Gull (Chroicocephalus philadelphia) is one of the world's only tree-nesting gull species, as seen here, about 8 feet up a white spruce in Churchill, Manitoba. These are graceful, noisy breeders, abundant along the edge of the boreal forest, where they can hunt over nearby ponds or marshes.
