Western-like birds down on the spit ). One of the 2 was mated
to a dark-primaried GWC. The other was incubating eggs, looked
like a female. It had a GWC-faded-yellow bill, and this
bird was mated to a darker primaried GWC. Saw another stock-
black-primaried gull loafing up on the road. And down by the
cabin somewhat below Joe's study area we observed a black-

out in the colony. ♂ of this pair had brownish primary
tips, yellow eye ring and a contrasting iris (greenish) - pupil.
The ♀ had jet black primary tips, and also a contrasting
