- Description: The Swallow-tailed Gull (Creagrus furcatus) is an equatorial seabird in the gull family Laridae. It is the only species in the genus Creagrus. It spends most of its life flying and hunting over the open ocean. The main breeding location is the cliffs of the larger Galapagos Islands, with lower numbers on most of the smaller islands. It is more common on the eastern islands where the water is warmer. It is the only fully nocturnal gull and seabird in the world, preying on squid and small fish which rise to the surface at night to feed on plankton. The Swallow-tailed Gull has no structural or plumage differences between the male and female. In the breeding season, the adult has a black plumaged head and a bright red fleshy rim around each eye. Outside the breeding season, the head is white and the eye rim becomes black. It has a grayish upper breast, gray mantle, and black wingtips. The mostly black bill has a contrasting white tip. The Swallow-tailed Gull is a near-endemic breeding bird of the Galapagos Islands, although a few nesting pairs nest on Malpelo Island off the coast of Colombia. When not breeding, it is totally pelagic, flying and hunting over the open oceans, and migrating eastward to the coasts of Ecuador and Peru. The Swallow-tailed Gull breeds from about 5 years old, with pairs frequently staying together from year to year. The female usually lays one speckled egg per breeding attempt. The egg is generally incubated for 31 to 34 days. A chick takes its first flight at about 60 to 70 days old, and is fed by the adults until about 90 days, when it leaves the land, possibly with the adults, to live over the open seas.
