[SBB] NOWA, MGWA along Stevens Creek, 4 Stilt Sandpipers in Alviso

[[[email protected]] (Mike Rogers)]

All,

Today 9/8/07, I started out birding along Stevens Creek north of Highway 101 in Mountain View. Things have been slow here during the hot weather of late, but today good numbers of passerine migrants were about. Highlights were a NORTHERN WATERTHRUSH in the east channel halfway between Crittenden Lane and the lone eucalyptus and a cooperative MACGILLIVRAY'S WARBLER south of here, halfway between the eucalyptus and the high tension line crossing. Other migrants included:

VAUX'S SWIFT - 15+
WILLOW FLYCATCHER - 3
HOUSE WREN - 2
YELLOW WARBLER - 1
WILSON'S WARBLER - 1
COMMON YELLOWTHROAT - 6
WESTERN TANAGER - 2
LAZULI BUNTING - 3
SAVANNAH SPARROW - 6

Three HOODED ORIOLES were near the end of L'Avenida.

I next headed to Moffett Field, checking the swallow flock along the North Perimeter Road, which included 15+ VIOLET-GREEN SWALLOWS, 10+ BARN SWALLOWS, and 3 VAUX'S SWIFTS. In the drying southeast corner of Crittenden Marsh were 17 RED-NECKED PHALAROPES, 1 BLACK-BELLIED PLOVER, 5+ SEMIPALMATED PLOVERS, a couple of KILLDEER, and a single SNOWY PLOVER. The nearby willows had 2 WILLOW FLYCATCHERS, 2 YELLOW WARBLERS, and an ORANGE-CROWNED WARBLER. A LOGGERHEAD SHRIKE was near the airstrip.

A one-hour check of Sunnyvale Baylands Park turned up 21+ YELLOW WARBLERS, 1 to 2 ORANGE-CROWNED WARBLERS, a migrant COMMON YELLOWTHROAT (in pines along Caribbean in the northwest corner of the park), and a WESTERN TANAGER.

At least 92 BARN SWALLOWS were on the wires near the old cannery building in Alviso and 4 juvenile STILT SANDPIPERS were in the first pond on the right as you walk out to the northwest along the railroad tracks that cross the EEC entrance road. I also tallied 7 LESSER YELLOWLEGS and many of both species of PHALAROPE.

An afternoon hike up to the top of Black Mountain from the Rhus Ridge trailhead didn't turn up many birds, although a pair of LAWRENCE'S GOLDFINCHES on the wires at the summit were interesting.
