Seabirds are birds that have adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene. In general, seabirds live longer, breed later and have fewer young than other birds do, but they invest a great deal of time in their young. Most species nest in colonies, which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, these birds of water filter through the migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even feed on each other. Seabirds can be highly pelagic, coastal, or in some cases spend a part of the year away from the sea entirely. Waders,
called shorebirds in North America (where "wader" is used to refer
to long-legged wading birds such as storks and herons), are members of the
order Charadriiformes, excluding the more marine web-footed seabird
groups. The latter are the skuas (Stercorariidae), gulls (Laridae), terns
(Sternidae), skimmers (Rhynchopidae), and auks (Alcidae). Also, the
pratincoles (Glareolidae) and the Crab Plover (Dromadidae), which bear
greater resemblance to waders, are closely related to the seabirds.
