This is probably a hybrid gull.
Flying near bridge.
Pair on bridge.
At least 50 altogether.
In mixed flock with Scaup.
Mating pair in the butterfly garden . Male on left in the main photo . A Lepidopteris told me that early matings like this are unsuccessful .
Finally out and about - sort of.
At their usual hangout; probably about 30 of them.
Gagging on a frog or a fish...? Later preening. In the BCNH pond.
