Seabirds fly low over water but gain altitude when crossing land, and the reverse pattern is seen in land birds. [ 34 ] [ 35 ] However most bird migration is in the range of 150 to 600 m (490–2,000 ft).
Some seabirds, principally those that nest in tundra, as skuas and phalaropes do, will migrate over land as well. [ 4 ] [ 72 ] The more marine species, such as petrels, auks and gannets , are more restricted in their habits, but are occasionally seen inland as vagrants.
They nest in burrows and often give eerie contact calls on their night-time visits. They lay a single white egg. They lay a single white egg. The chicks of some species, notably short-tailed and sooty shearwaters, are subject to harvesting from their nest burrows for food, a practice known as muttonbirding , in Australia and New Zealand.
Outside the breeding season, skuas take fish, offal, and carrion. Many practice kleptoparasitism , which comprises up to 95% of the feeding methods of wintering skuas, by chasing gulls, terns and other seabirds to steal their catches, regardless of the size of the species attacked (up to three times heavier than the attacking skua).
As we saw all fall and a good portion of this winter season, if the weather is not real cold and the ground is not snow covered, the birds seem to manage fending for themselves out in the forest ...
In most seabird colonies several different species will nest on the same colony, often exhibiting some niche separation. Seabirds can nest in trees (if any are available), on the ground (with or without nests), on cliffs, in burrows under the ground and in rocky crevices. Colony size is a major aspect of the social environment of colonial birds.
