the two next black, but the fhafts and middle part white j the
tips of the next two white, beneath a black bar: the reft, as well
as the fecondaries, afti-colour: in other things refembling the
black-headed Gull.
In my own collection is one which anfwers in all things to the
black-headed Gull, except in the feathers of the head being white,
with here and there a dufky fhade, and a large fpot of the fame
on the ears j but on raif.ng up the feathers of the head, one immediately
obferves that they are only tipped with white, it being
merely a young bird of the firft year * j as this fpecies does not
gain the full black head till the fecond or third moult.
