Black-headed Gull - Hybrids

This section deals with hybridisation between Black-headed Gulls and other taxa.


Hybridization of Black-Headed Gull with other small gulls is rare, but occurs. Few instances are well documented*. Hybrids show characteristics of both parent species but are often indeterminate and difficult to identify.

Second- and third- generation hybrids are even more problematic. Black-Headed Gull hybridises with other hooded gull- species as well as with small non-hooded gull-species.

*Additional info in the form of descriptions or photos is welcomed. Should you have any additional material, please contact one of the moderators of these pages (see names in top left-hand corner, e-mail addresses can be found on the Home page.)
