Sorry for the late report, but I was out of data.  I had a pair of Black Throated Gray Warblers near the visitor center at Mitchell Canyon (Mt Diablo state park) on Tuesday 8/11 around 2:30.  They were the only warblers that I saw in fact.  There were also many White Breasted Nuthatches.

Vollmer Peak migrants

dp_eas
 

This am there were a few migrants at Vollmer Peak in Tilden: 1 fresh/ heavily streaked juvvy Chipping Sparrow, 2-3 Western Tanagers, and a House Wren. The 4 Western-type Flycatchers and 7-8 Wilson's Warblers I observed may have been migrants or local breeders.

As usual, there were several Rufous-crowned Sparrows farther down the Skyline Trail just south of the Big Springs Trail junction.

Vollmer Peak is near the steam train.

Are the majestic old Monterey pines here slated for the massive clearcut which I believe begins tomorrow?

GGAS Second Friday Birdwalk, August 14, 2015, Point Isabel Regional Shoreline

Friends!

Golden Gate Audubon Society Second Friday Birdwalk, Point Isabel Regional Shoreline, Richmond CA, August 14, 2015.
Our 4th annual Return of the Shorebirds birdwalk here.

One Whimbrel, one Long-billed Curlew, seven members of our Meet-up Group! Birds O'the Day: Wilson's Phalarope and fledgling Common Murre (thanks, Dave Quady for finding the former and Id'ing the latter). Visitor of the Day was Gerhard H. from Linz, Austria!

Good views of worn-plumage Short-billed and Long-billed Dowitchers as illustrated by Sibley in the second edition of his big book.

We started with eBird data about where the birds that are not at Point Isabel this week still are:

The nearest American Wigeon is up at Willows, CA. Northern Shovelers are in the High Mountain West. Nome and St. Paul Island in the Bering Sea (AK) have the Northern Pintails, Green-winged Teal and Dunlin. Common Goldeneyes are in central southern Alaska and strung across the US/Canada border from the Pacific to Nova Scotia, as if waiting for passport control to admit them! Ditto for Horned Grebes, from WA to MN. Mew Gulls are in Alaska (Nome, Kodiak Island, south central Alaska, Juneau, Skagway) and near Vancouver, BC.

Thanks to all who brought spotting scopes today! If anyone Id’ed the strange object at Lime Point (northern foot of the Golden Gate Bridge) please let me know! Thanks!

Here are the 28 species seen today:

Clark's Grebe
Double-crested Cormorant
Great Blue Heron
Great Egret
Snowy Egret
Black-crowned Night-Heron
Turkey Vulture makes it official!
American Avocet
Black-bellied Plover breeding plumage
Willet
Whimbrel 1
Long-billed Curlew 1
Marbled Godwit 2
Western Sandpiper
Short-billed Dowitcher 8
Long-billed Dowitcher 1

Western Gull
Least Tern 2 fide Ande B.
Forster's Tern
Anna's Hummingbird
Nuttall's Woodpecker
Black Phoebe
American Crow
Chestnut-backed Chickadee

I would just like to add another bird I observed this morning to Alan Kaplan's list during his GGAS bird walk:

It was a Semipalmated Plover in a mud flat on the east side of the trail.

Good Birding,

Lesser Yellowlegs bonanza at Eden Landing

Derek
 

Jim Chiropolos and I did our tried and true bike ride from Garretson
Point down to Eden Landing and back this morning. Highlight was 22
Lesser Yellowlegs at Eden Landing in the nearest pond to Dune Circle
in the large housing sub-division. We've found Eden Landing to be a
best location on the East Bay shoreline to find Lesser Yellowlegs; we
don't get to Don Edwards often but have had good success there too.
Also in that area were three Red-necked Phalaropes. We had 20 species
of shorebirds overall on the ride, including roughly 20 Snowy Plovers
(15 at Hayward Shoreline and 5 at Frank's Dump). We also had a Green
Heron at the small pond off Regatta Way just north of San Lorenzo
Creek. We think it's the first Green Heron we have had in all the
years we've been biking/birding that route.

Today I joined a Golden Gate Audubon bird walk led by Steve and Carol Lombardi from the end of Grant Ave. to the end of Winton along the San Francisco Bay Trail in the northern area of the Hayward Regional Shoreline. It started at 11:00 a.m. in an attempt to time the high tide roost at Frank's Dump. These are some of the shorebirds and waterfowl we observed:

1. Black-necked Stilt with juvenile on a small, low island in pond.

2. American Avocets

3. Greater Yellowlegs

4. Willets

5. Long-billed Curlews

6. Marbled Godwit

7. Ruddy Turnstone (at least two of them)

8. Red-necked Phalarope

9. Red Knot

10. Sanderling

11. Least Sandpipers

12. Western Sandpipers

13. Caspian Tern

14. Black Oystercatcher ( standing on pole which was offshore in the water.)

Good Birding,

Ruddy Turnstones and Knots at Hayward

SteveLombardi
 

15 sharp-eyed birders braved Sunday's heat to walk from Grant Ave. to Winton Ave. on the Hayward Shoreline.
Highlights were 25 Ruddy Turnstones - several on the sewage outlet pipe near Grant Ave. and the others at Frank's. Also, 3 Red Knots hunkered down at Frank's. Thanks to Johan for finding the Knots and thanks to Robert for compiling the list, and thanks to everyone for good spotting and enthusiasm.

Aquatic Worms on Berkeley Beaches

Jim Chiropolos
 

Biking to work this morning the two sandy beaches in Berkeley (north of Ashby and south of University) were full of debris above the low tide and below the high tide line. Walking down to inspect to "debris", the debris consisted of thousands of what I believe are dead aquatic worms - some maybe above a tunnel. 


I have never seen one dead worm on a beach before - and there were thousands. Does anyone have any idea what type of phenomena this is? I do not know if this is also occurring at mudflats. I have a picture I can email anyone offsite.


Apologies for the possibly non-bird related post.

I know it usually happens around the King tides in late December and late January.

Could be the heat wave had something to do with it.

This could well be connected with the toxic algae bloom that now stretches from California to southern Alaska.

Baird Sandpiper and Common Tern, Alameda

Mark Rauzon
 

This afternoon (8/18) in Alameda I found a Baird's Sandpiper at the end of Alameda South Shore among the gulls and seaweed next to the seawall. It was with Sanderlings, Western and Least Sandpipers making for good comparisons. Here are some photographs    http://rauzon.zenfolio.com/p989996334/h53e6cc15#h53e6cc15

Also I stopped at Ballena Cove at the north end of Alameda, and found two Common Terns among the 80 or so Forester''s Tern. Both basic and alternate plumages pictured here. http://rauzon.zenfolio.com/p989996334/h53e6cc15#h53e6d00e

Good luck.
