44 Species at 3 Locations

Anatidae (Ducks, Geese, and Waterfowl)
Gadwall HRS
American Wigeon HRS
only two seen in the \"ruddy duck, shoveler, phalarope\" pond south of the parking area at Frank\'s Dump.
Northern Pintail HRS
four seen - and another group of two (possibly the same birds)
Greater Scaup HRS
one male seen
Bufflehead HRS
single female
Odontophoridae (New World Quail)
Podicipedidae (Grebes)
Horned Grebe HRS
There were nearly a dozen Eared Grebes diving together amongst the gull flock, and two Horned Grebes.
Eared Grebe HRS
Most of the Eared Grebes were in winter plumage, but two retained the all-dark head and neck, red eyes, and hints of gold feathers around the ears.
Phalacrocoracidae (Cormorants and Shags)
Ardeidae (Herons, Egrets, and Bitterns)
Cathartidae (New World Vultures)
Accipitridae (Hawks, Eagles, and Kites)
Golden Eagle SRP
Guess what? Part of Sibley Volcanic Regional Park is *not* in Alameda County! It\'s over the border in Contra Costa County. The Golden Eagle was over the Orinda Gateway Blvd exit -- not in Alameda County at all.
Cooper's Hawk HRS
Juvenile accipiter entered the brush beside our parked car, was very difficult to see in the brush. Only the breast & belly were well-seen, and these were strongly streaked with markings degenerating to a series of nearly distinct triangle marks about halfway down the breast. The bird eventually flew through the brush and made a right angle turn to cross the parking lot directly in front of us. Both observers spent more time saying \"Ooooh\" than noting field marks on this flight - result: no ID, but a beautiful memory. There was an active Cooper\'s Hawk nest in this parking lot in spring 2007, so tentative ID is Cooper\'s Hawk, but the more accurate ID is \"accipiter sp.\"
Red-tailed Hawk HRS SRP
Charadriidae (Plovers and Lapwings)
Scolopacidae (Sandpipers and Allies)
Willet EM
Laridae (Gulls, Terns, and Skimmers)
Columbidae (Pigeons and Doves)
Tyrannidae (Tyrant Flycatchers)
Corvidae (Crows, Jays, and Magpies)
Western Scrub-Jay SRP
Seen at the \'back\' entrance to Sibley - not in Alameda County.
Hirundinidae (Swallows)
Aegithalidae (Long-tailed Tits)
Bushtit EM
Emberizidae (Buntings and New World Sparrows)
Fringillidae (Siskins, Crossbills, and Allies)
Passeridae (Old World Sparrows)

Trip Notes

Frank's Dump: We hustled through Frank's Dump today - 45 minutes out to the bridge and back, with a long time scoping the big pond south of the parking lot from many angles. We managed to find four new duck species, each represented by 1 - 4 individuals: Northern Pintail, Greater Scaup, Bufflehead, and American Wigeon. This is starting to look better for our upcoming big day.

But the eucalyptus grove coughed up N-O-T-H-I-N-G. House sparrows and not one other species -- until the juvenile accipiter came between us & the car. That was a treat in the desert!

Emeryville: Drove directly to the last parking lot at the end of Powell and walked out the fishing pier. No other stops made at this location Also saw Accipiter sp.
