What is "black-headed gull"

n. A small gull, (taxlink Chroicocephala ridibundus species noshow=1), which breeds in much of Europe and Asia, and also in coastal eastern Canada.

The black-headed gull (Chroicocephalus ridibundus) is a small gull that breeds in much of Europe and Asia, and also in coastal eastern Canada. Most of the population is migratory and winters further south, but some birds reside in the milder westernmost areas of Europe. Some black-headed gulls also spend the winter in northeastern North America, where it was formerly known as the common black-headed gull. As is the case with many gulls, it was previously placed in the genus Larus.

The genus name '' Chroicocephalus'' is from Ancient Greek khroizo, "to colour", and kephale, "head". The specific ridibundus is Latin for "laughing", from ridere to "laugh".
