Black-headed Gull - Hybrids

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

Introduction

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.
