The tropics are occupied by species that live there year round as well as by species from the far north or the far south that visit for the winter. Northern and southern visitors seldom see each other, since the seasons are reversed on either side of the equator. Diet but some species may make shallow dives or alight on the surface. Reproduction S pending most of their lives far from such predators as cats, dogs, and rats, and flying out of reach of sharks and other marine predators, tubenoses enjoy relatively long, secure lives. They breeding strategies seem .
Most tubenose species breed in summer at the highest latitudes of their range.
Thus, many species native to the Southern Hemisphere breed on Antarctic or subantarctic islands. Other species breed in winter, but closer to the equator. Larger albatrosses build large nests on the ground. Giant petrels build poorer nests. Smaller tubenoses usually nest in a chamber at the end of a long burrow which they dig for themselves.
