relict gull
The relict gull or Central Asian gull (''Ichthyaetus relictus'') is a medium-sized gull. It was believed to be an eastern race of the Mediterranean gull until 1971 and was traditionally placed in the genus ''Larus''.
==Description==
The gull is 44 to 45 cm long with a stocky, thick body. Non-breeding adults feature uniformly dark-smudged ear-coverts and hind crown, white-tipped wings, prominent, isolated black subterminal markings on outer primaries, and no white leading edge to outer wing. Breeding birds have black hoods (including napes) with grey-brown foreheads, and broad, white, half-moon colouring behind, below, and above their eyes. Their legs are orange and their bills scarlet. The name comes from its status as a relict species.〔Ming Ma, Ying Chen, Kedeerhan Bayahen, Baowen Hu, Fei Li, Jiaqing Wu, Xiang Gao, Yu Mei, ("Seasonal changes in the number of Relict Gull (''Larus relictus'') at Ebinur Lake, Western China" ), ''Journal of Arid Land'', 2010, volume 2, number 2, pp 151−155, Retrieved May 2, 2015〕
