[SBB] Palo Alto, CCFS - 10/22/05

[[[email protected]]]

All,

I started out this morning 10/22/05 at the Palo Alto Baylands, hoping that the dense, low fog would send a confused shearwater south into the bay (as it did back on 7 Sep 1994). I ended up having to be content with 5 BROWN PELICANS and lots of dabbling ducks on the bay, so I guess the only one confused was me. Two WHIMBREL and 2 SEMIPALMATED PLOVERS were on the uncovering mudflats here, along with good numbers of the other expected shorebird species. The eucalyptus trees by the ranger station had a lingering YELLOW WARBLER and the nearby fennel had 70+ AMERICAN GOLDFINCHES and a "morphna"-type SONG SPARROW. An adult PEREGRINE FALCON flew north overhead.

At the end of Embarcadero Way a single TOWNSEND'S WARBLER was hanging out with the many Yellow-rumped Warblers. I could find no other doves in among the 150+ MOURNING DOVES over by the ITT towers behind the Emily Renzel pond.

I next headed to CCFS, where I spent a couple of hours working the riparian corridor from the banding trailer north to the former heronry near the waterbird pond. Highlights included 1 TREE SWALLOW, 1 BLUE-GRAY GNATCATCHER (an unbanded hatching-year bird, and therefore different from the bird banded on 1 Oct, which was different from the banded bird that wintered in the area the past few winters), 6 HOUSE WRENS, 2 WINTER WRENS, and 3 ORANGE-CROWNED WARBLERS. At least one WOOD DUCK (a  female) was in Coyote Creek up near the old heronry.

The banders caught a hatch-year male SPOTTED TOWHEE today, unusual for the bayside. Also of note was the season's first (and so far only) SWAINSON'S THRUSH, a hatch-year bird banded on 19 Oct. A NASHVILLE WARBLER was banded on 11 Sep and single MACGILLIVRAY'S WARBLERS were banded on 28 Aug, 10 Sep, and 18 Sep.
