Tweeters,
Over 70 F, clear skies, four gillnets, and very light northerly breeze
at Turning Basin #3. Spotted a "bump" on one of the lower crossbars of
the east power tower: PEREGRINE FALCON feeding on a Rock Pigeon. Since I
had no scope, I decided to walk down to the tower to take a better look.
Over half the pigeon was gone, and the PEFA was working on what remained
of the breast, while holding on to one of the wings. While I watched, an
American Crow landed on a nearby crossbeam, then hopped over to within
3ft of the falcon, then even closer. The crow started cawwing and the
falcon started vocalizing, too. The crow eventually departed, then
returned to harrass the falcon, then finally flew south. Note: The
falcon, larger than the crow, was an adult with a very light breast, and
no leg bands.

Lots of gulls again on the restoration peninsula mudflat, but they
departed when two guys in a pale yellow MadRiver Canoe landed there. A
NORTHERN FLICKER was calling from the south side of TB3.

Birds seen during this scan include the following:
Canada Goose (3)
Mallard (5)
Common Merganser (2)
Double-crested Cormorant (2)
Great Blue Heron
Peregrine Falcon
Mew Gull (22)
Ring-billed Gull (5)
Glaucous-winged Gull (29)
Rock Pigeon (39; not including the PEFA's lunch)
Northern Flicker
American Crow (5)
Bewick's Wren
European Starling (about 200 on the west power tower - Hamm Creek)
Song Sparrow (singing from the top of a butterfly bush)
House Finch

May all your birds be identified,
