Migrant activity was again at best moderate, dominated
by Yellow Warblers. At the south end of Lake Merced, no
sign of yesterday's Blackpoll Warbler. Two Yellow-rumped
Warblers (both Audubon's) were my first of the season.
At Harding Park, a prolonged bout of pishing pulled
in 4 Common Yellowthroats, a Black-throated
Gray Warbler, and a Wilson's Warbler to the Albizia
near the entrance.
At Pine Lake Park, a myrtle east of the lake had
a male Black-throated Gray Warbler, a Townsend's
Warbler, and two Warbling Vireos.
