Razorbills, Machias Seal Island, Maine/New BrunswickThe razorbill is the only species in the genus Alca. It’s relative, the great auk, went extinct in the mid 19th century. They are monogamous birds and spend the vast majority of their lives at sea, coming ashore only to breed. This mated pair appears to be doing just that. Photographed on Machias Seal Island off the coast of Maine. Nikon D300 with Nikkor 200-400mm lens (at 400mm) ISO 400, f/6.3 at 1/2000th of a second.
