Chroicocephalus genei (Slender-billed Gull)

Synonyms: Larus genei; Larus spec

Wikipedia Abstract

The slender-billed gull (Chroicocephalus genei) is a mid-sized gull which breeds very locally around the Mediterranean and the north of the western Indian Ocean (e.g. Pakistan) on islands and coastal lagoons. Most of the population is somewhat migratory, wintering further south to north Africa and India, and a few birds have wandered to western Europe. A stray individual was reportedly seen on Antigua, April 24, 1976 (AOU, 2000). The genus name Chroicocephalus is from Ancient Greek khroizo, "to colour", and kephale, "head". The specific genei commemorates Italian naturalist Giuseppe Gené.
