During our winter stay on St. George Island, Florida, I like to explore the beach along the Gulf of Mexico. One day, I saw these two Bonaparte’s Gulls resting on the sand. At 13½ inches long, they are the smallest regularly occurring gulls that we see in North America. This photo shows them in non-breeding plumage, which includes a dark spot behind the eye. In breeding plumage, the head will be entirely black. It takes two years for a Bonaparte’s Gull to molt into adult plumage like the bird on the right. The bird on the left, with more black in its wing feathers, is in 1st winter plumage.
