The Red-legged Kittiwake is a species of seabird that breeds on islands in the Bering Sea and spends non-breeding season on the open ocean.
Kittiwakes are in the family Laridae with the gulls. There are two species of kittiwake: Red-legged and Black-legged. The species are very closely related. They get their name from their shrill-sounding call.
The population trend for the Red-legged Kittiwake is decreasing. The species faces threats including reduction in prey species from possible over-fishing or movements in fish populations due to global warming. The conservation status for the Red-legged Kittiwake is Vulnerable to extinction as of December 2014.
From IUCN Red List: The Red-legged Kittiwake is listed as Vulnerable
on the IUCN Red List and was last assessed in 2015 by BirdLife International. This species is listed as Vulnerable owing to a rapid population reduction in the last three generations (44 years). Trends in the main population appear to have stabilised and, unless declines recommence the species may warrant downlisting to Near Threatened in future.
