SF sea watch -- Sooty Shearwaters, Red-necked Grebe et al., 5/4/16

Paul Saraceni

Sea-watched this morning (7-9 AM) from the closed parking at the south end of the Great Highway, along with Dominik Mosur and Hugh Cotter. Overcast, light SW winds, visibility improving to the horizon as the morning went on.

Dom was there ahead of me for the early shift and had already noted phalaropes (presumed Red-necked) departing from the ocean surface, a big push of Pacific Loons, and the large congregation of Western Grebes (800+) spread out over the ocean surface. There was also a developing "feeding frenzy" of cormorants and loons that continued on-and-off during our time there.
