This morning I conducted a seawatch from the south-most parking lot of the Great Highway, 7:15-10:25 AM. Except for a few brief periods when the fog moved in a bit before retreating, conditions were good with overcast skies, visibility out to the horizon, and moderate west wind. A lot of birds were moving and I enjoyed my best seawatch in quite a while.
At 8:40 AM I observed a CASSIN'S AUKLET flying N, only ~50 yards out. Just the 2nd of this species I have ever observed from shore in SF.
At 10:25 AM I observed a RED-NECKED GREBE flying N not far out from the surf. It landed and then disappeared under a swell.
There was quite a nearshore movement of jaegers -- my numbers below are conservative and I endeavored to not double-count, based on plumage differences.
A strange sighting was what otherwise appeared to be a male Surf Scoter in flight (typical head markings and same size and structure as other Surf Scoters it was flying with), but having bright white on the outermost-1/3 of its wings (not white wing-patch as on a White-winged Scoter). A plumage aberration I have never seen before. If you are sea-watching there keep an eye out for this individual.
