I conducted 1-2 hr. sea watches each of the mornings of Sept. 7-9 (with Hugh Cotter on the 9th) from the southmost parking area of the Great Highway. Each morning featured WSW winds with excellent visibility on the 8th & 9th. Jaegers were the highlight each morning, including 6 (5 Parasitics, 1 Pomarine) in view at one time on the 8th.
Observations of local interest for each day -- 7th/8th/9th:
Surf Scoter: 0/4/2 Pacific Loon: 1/3/2 Red-thr. Loon: 1/1/0 Common Loon: 6/8/5 W. Grebe: 3/2/3 SOOTY SHEARWATER: 12/800+/3 Pelagic Cormorant: 0/0/1 Osprey: 1/0/0 Semipalmated Plover: 0/1/0 Red-necked Phalarope: 0/0/1 POMARINE JAEGER: 1/3/1. On the 8th, 1 possible dark-morph, subadult Pom was scoped on the water adjacent to an ad. Parasitic, which it dwarfed. The bird was bulky, thick-necked, short-tailed with no projections, and all-dark but for white primary flashes observed during brief flight view. In fact it was highly suggestive of a South Polar Skua, but photos could not be obtained as the bird was rather distant. PARASITIC JAEGER: 5/9/6 (ads. and imms.; on the water and in flight, chasing Elegant Terns) LONG-TAILED/PARASITIC JAEGER SP.: On the 9th Hugh and I observed a dark-morph juv. flying S just beyond the surf. It was flying rather buoyantly and was dwarfed in size by the California Gull it briefly pursued. Common Murre: 7/12/4 (mostly juvs. on the ocean) Pigeon Guillemot 1/4/1 Barn Swallow: 3 over the ocean on the 8th. Also: Harbor Porpoise, Bottlenose Dolphins, and a California Sea Lion on the 9th.
On the 9th, following the sea watch, Hugh and I checked a few locations in W SF. Small numbers of western migrants were noted, with a few species of interest. At the S. Lake Merced concrete bridge, a calling LESSER YELLOWLEGS flew over the north lake heading NW. Red-necked Phalaropes continue on the north lake with at least 47 in several groups a ways out. 2 Virginia Rails and 1 Sora called un-prompted. 1 male Great-tailed Grackle continued. A Coyote crossed John Muir Drive heading towards the lake.
At the East Wash, less common species included 1 Selasphorus hummingbird, 1 Red-br. Nuthatch, 1 Blue-gray Gnatcatcher, and 1 "non-local" (by call) Red Crossbill.
