SWALLOW-TAILED GULL VIDEO
SPECIES INFO
The Swallow-tailed Gull (Creagrus furcatus) is an equatorial seabird in the gull family Laridae. The species is endemic to the Galápagos Islands. When it is not breeding it is totally pelagic (flying and hunting over the open oceans), migrating eastward to the coasts of Ecuador and Peru. A notable aspect of the swallow-tailed gulls are the fleshy red rims around the eyes; it is speculated that these may aid its noctural vision.
It is unique within the gulls for feeding exclusively at night (Harris 1970), feeding mostly on squid. It breeds colonially throughout the year; unlike most other gull species it lays a single egg per breeding attempt (Agreda & Anderson 2003) .
A type of fish that glows can be seen from above the water, making it easy for the Swallow-tailed Gull to see and attack it at night.
