This morning I made a visit to the NW Presidio and then did a 1-hr. searwatch.
At Lobos Dunes, there was very little migrant activity (single Yellow & Orange-crowned Warblers). 2 Bewick's Wrens were near the boardwalk and a Great Horned Owl was calling @ 8:15 from the forest NE of the dunes.
At Ft. Scott, a group of 5 WESTERN BLUEBIRDS was on the west side of the parade grounds, feeding on the ground and perching up on the rooftops. The flock included 2 spotted juveniles.
The sparrow flock (currently White-crowns and Juncos) frequenting the edges of the basketball court and soccer field is already worth checking: this morning it included 2 CHIPPING SPARROWS.
Other migrants in the scattered trees around the parade grounds included:
Yellow Warbler 2
Townsend's Warbler 1
Wilson's Warbler 1
W. Tanager 2
At the s. end of Ocean Beach, viewing conditions were perfect. Observations of interest (9-10 AM):
