Lesser Black-backed Gull

Especially during the last 25 years, Lesser Black-backed Gulls are now regular visitors to eastern North America—and the range is expanding. This gull is common across Europe. Almost all seen in North America are the race that breeds in Iceland, Britain, and western Europe—as you can see in this photo from Sanibel Island in March, the back is much lighter than the wing tips. The yellow legs are a good field mark for the species; similar gulls have pinkish or yellowish legs.
