Subject: [SFBirds] Recent sightings
Here's a compilation of bird sightings I found notable from San Francisco for the last part of August:

8/25/17 : two BAIRD'S Sandpipers were in one of the construction ponds across the fence from Yosemite Slough Restoration Area. These ponds/excavations are likely the beginning stages of a foundation for a bridge that is to be built across Yosemite Slough, bisecting a crucial remnant of bayside open space and wildlife habitat. Perhaps birders will finally acknowledge and feel the effects of gentrification when it affects a productive birding location. You can be sure the Black-tailed Jackrabbits and Beechey's Ground Squirrels will feel the change.

8/26 - (5) RED Crossbills briefly landed in summit eukes on Mount Davidson. It's been a couple of years since "local" type Crossbills have been around SF in appreciable enough numbers for closer study, but from what I can recall, these birds were not it. They appeared smaller billed and their "jip" calls sounded higher pitched. A pair of Bullock's Orioles were good migrants for late summer on Mt. Davidson.

8/30 - Back at Yosemite Slough, a lone BAIRD'S Sandpiper flew into one of the construction ponds about one hour before the predicted 6.3' evening high tide.

8/31 - The high pressure was in full effect on Mount Davidson at sunrise. Migrants/arrivals of note included:
RUBY-CROWNED KINGLET - a slightly early first arrival
Bewick's Wren - rare away from Glen Canyon/Presidio/Funston/Bayview Hill
Cedar Waxwing
Savannah Sparrow
Lazuli Bunting - 3
Red Crossbill - at least 3, small billed/high pitched "jip" types, didn't stick around for long

9/1 - Lake Merced at the concrete bridge after work:
Record high temps (~90oF at 6:15 p.m)
Virginia Rail
MacGillivray's Warbler

Great to read about all the people getting out and enjoying migration.
