Possible melanistic/leucistic RBGU? Strange coloration reminiscent of Heermann's Gull-- gray body and white head with black legs.
观察细节
Loafing on hillside marked 'HILL' in Google Maps image attached to the checklist. Another bird is possibly a strangely-colored RBGU, which I've seen a few months ago at this location and grabbed a photo of.
