The
Gray-hooded Gull is a bird that is normally found in scattered parts of
Africa and South America. In North America, they were unknown, until a
sighting in Florida in 1998. In 2011, a bird found on Coney Island in
New York City caused quite a commotion, with birders flocking from around
the region to see the mega-rarity.
Habitat: Found around freshwater wetland habitats
during the breeding season, as well as tropical and subtropical coastal
areas. Found around a greater variety of aquatic habitats outside of
the breeding season.
Diet: Omnivorous. Feeds heavily on fish when
available, but will also feed on insects, mollusks, crustaceans, other
invertebrates, eggs, fledgling birds, refuse, and carrion.
Behavior: Foraging technique depends on location
and what food items are availble.
Nesting: In their native range, Gray-hooded Gulls
are colonial nesters, with colonies in areas of wetland vegetation or on
islands. The nest itself differs depending upon location. It may
be just a simple scrape on the ground, or it may be a substantial structure
built of grasses and wetland vegetation. The female lays 2 or 3 eggs.
Song: Loud around nesting colonies, with a
crow-like "cawing" call.
Migration: Not truly migratory, as most birds stay
relatively close to breeding locations. Some birds may disperse
outside of breeding, however, but no regular or predictable migration is
noted. African and South American populations evidently do not
interact, but they are still considered the same species.
Similar Species:
Similar to the Brown-hooded Gull, a species not seen in North America. If
seen well, the gray hood and other characteristics should be diagnostic in
North America, should it occur again.
