Guide to Boreal Birds
Hundreds of these shorebirds may be seen from fishing boats far at sea; bobbing like corks, they look like miniature gulls riding the waves. While they are at sea the greater part of their diet is made up of tiny marine animals known as plankton. On land they forage around tundra pools for the aquatic larvae of mosquitoes, midges, and beetles. After egg-laying the male takes over the duties of incubating the eggs and rearing the young.
