The
Great-winged Petrel, also known as the Gray-faced Petrel, is a seabird of
the far southern oceans. They breed in scattered locations throughout
the southern oceans, from the coasts of southern Australia and northern New
Zealand, to islands in the south Atlantic and Indian Oceans.
Non-breeding birds wander throughout the southern hemisphere, but they have
occasionally been found in the northern hemisphere as well. North
American records consist of a handful of sightings off the coast of
California.
Habitat: Found in scattered areas in the southern
oceans during the breeding season, using coastline ridges and scattered
island groups as nesting colonies. Pelagic at other times of the year.
Diet: Feeds mostly on squid, but will also take
small fish and crustaceans.
Behavior: Soars over the ocean's surface, dipping
down to grab prey items from the ocean's surface or just below.
Nesting: Nesting typically occurs near the base of
a small shrub or other plant, or between tree roots. A single egg is
laid, with an incubation period of about 8 weeks. Both parents help
feed and tend to the young after hatching.
Song: Has a high-pitched, shrieking call.
Migration: Many birds are found near nesting
colonies even outside of the breeding season, but others wander widely
across the southern oceans.
Conservation Status: There are indications that
global populations are decreasing, but at this time there are no serious
threats to the species. The
IUCN
lists the Great-winged Petrel as a species of "Least Concern".
