Well, maybe not so much a blog as a collection of San Francisco birders' accounts of particular occasions. They appear in reverse date order.
Sunday, August 27
Around noon today (Sunday) I did about 45 mins of
birding at Ft Mason.
action is really concentrated around the
Himalayan blackberry brambles. Of
course the fruit is a major draw and there are more berries cascading
off the bushes than Ive ever seen! The foliage of this plant (like the
native California blackberry) harbors tiny insects eaten by
insectivorous songbirds. If Eucs are historic, by golly why not Himalayan
blackberry too. Brambles have been hacked away in most of the
places it used to dominate
Spiny yes, invasive yes, but good for wildlife
and birds, especially
and Brush Rabbits, you bet! Aldo Leopold referred to a 6x6 ft patch of
Himalayan blackberry bramble as the "acme of Quail cover". And this
stuff used to be everywhere in SF and the Presidio, and so did Quail and
brush rabbits... hmmm... So far we dont have native
cover sources that can
the protection afforded by brambles.
As birders we should make sure the NPS, Presidio Trust and Rec and Parks
department realize its importance to local and migratory wildlife and
maintain stands of this exotic plant at least
until native cover is as
Highlights around the brambles:
Yesterday eve between 550 and 650pm did a big hr with Andy
Kleinhesselink on the normal Presidio route. It
was late, windy and cold.
ended up with 43 sps. and lots of misses.

highlight in my book... but noteworthy)

Fred Chambers and I had a good morning of
Jumping to the end of the report, the best bird of the morning was a 1st
year, female Northern Parula in the very tops of the eucs at the
southwest end of
Lake in Golden Gate Park.
Kobbe and Upton: Warbling Vireo and Western
among other birds that are regular there.
Crissy Field: usual suspects with the best bird
a Great Yellowlegs.
Golden Gate Park
North Lake: Near the redflowering euc at the NW corner of the lake
there was a small flock that
included Pacific-slope Flycathcer, Yellow
Wilson's Warbler, Warbling Vireo and Western Tanager. A Common
Yellowthroat was in the bulrush by the
island north of there.
Middle Lake: Loaded with migrants! The south end of the lake was where
it was happening. Birds were apparent from the down eucalyptus around
the entire end of the lake on the both sides. Yellow, Wilsons and
Hermit(1) Warbler, Pacific- slope Flycatcher, Bullock's Oriole (2),
Steller's Jay (2) and of
the Norther Parula. American and Lesser
were there too.
We talked with Jason Yakich
who reported seeing an American Redstart, a Lazuli Bunting and several
Townsend's Warblers at the south end of Middle Lake too. It was very
active and I'd think there is an excellent chance there are more
birds to be found there.

The migrants definitely congregated at West Wash.
I took my Audubon Field Trip there around 8:20am and we spent two hours
viewing from north end of the Ft. Miley parking lot which provides
grteat viewing over the slope down to the West Wash along El Camino Del
