Yesterday, Friday, Nov. 25th I saw a yellow-shafted flicker with two bands on one of his legs - a bright green band, and a bright yellow one. Birding is great out of my Rossmoor condo window, Walnut Creek.

Pacific Commons Slaty-backed Gull

Just a word of caution to those chasing this bird that the dump to the west is closed on the weekends - which greatly reduces the chances of seeing it here. I speak from personal experience!! Two tries - one on a Saturday - no bird.

Slaty-backed Gull continued at Pacific Common

Jerry Ting
 

I went back to Pacific Common Linear Park today and birded from 11:30AM - 2:00PM. The Slaty-backed Gull showed up around 12:40PM and landed on the northeast corner of the pond. It was quite active busy showering, flipping, jumping and preening for a good 10+ minutes and then took off heading southwest. I spent another hour and a half but did not see the bird again.

There were also hundreds of Westrn, Herring, Glaucous-winged, California, Ring-billed, Western x GW and Herring x GW hybrids prestented with various cycles. I think I also saw a couple of Thayer's but bot 100% sure.

A couple of shots of the Slaty-backed Gull that I took today can be seen at:

Thanksgiving yard bird: Ruby crowned Kinglet

Win Kryda <winkryda@...>
 

We had a Ruby-Crowned Kinglet gleaning water from a bamboo plant in
Montclair (Mountaingate and Castle intersection). Our Townsend's Warblers
have been regular to our feeders for several weeks now and the Downey WP
have been coming to the suet cakes for weeks now especially befor the rains.
Hermit Thrush have been devouring the holly berries.

Re: Gull ID Help Needed

Joe Morlan
 

Jerry,

Nice photos as usual.

I don't think your bird is likely to be a "Vega" Gull (Asian race of
Herring Gull) for several reasons. The bill is too bright, almost orange in color. Vega should be more like Herring Gull with a thinner dull yellow bill. More to the point is the underwing pattern which shows a lot of dark gray on the underside of the trailing edge of the wing. Again, Vega Gull should be more like Herring Gull, with the underwings all white except for black tips and white mirrors.

To me, the bird looks much like a Western Gull and I would suggest that it's either an odd Western Gull with delayed plumage development on the head causing the dark smudging, or more likely a hybrid Western X Glaucous-winged Gull which are not all that uncommon in the Bay in winter. Most of those hybrids have pale underwings, like Glaucous-winged, but they back-cross extensively in the Puget Sound region and there is quite a continuum of variation.

I went to Pacific Common Linear Park yesterday afternoon in hopes of seeing the Slaty-backed Gull again. After 2 hours of searching and sorting out numerous gulls in the pond I was not able to re-find it.

However, I did re-find an interesting gull that I photographed on 11/13 and took a couple of images of it. This gull has dark back (as dark as Western Gull), smudgy head (way too smudgy for Western), yellow bill, brown eyes, broken white eye rings and pink legs.

So far I have people suggesedt Western, Herring, Herring hybrid, Western x Glaucous-winged hybrid, Vega and Vega hybrid but no one seems to have a solid answer. I did some studies on Vega Gull online and find it a very possible candidate.

Bayside Thursday a.m.

Bob Power <rcpower@...>
 

Hi all,
If my records are right, this is my 8th annual 7-10 Thanksgiving a.m. hallpass
bird blitz.
Highlights included: Osprey -- Brooks Island.
Pelagic Cormorant - 5 Marina Bay Parkway inner harbor jetty -- high count for me
on the bay
Eurasian Wigeon - 1+ - Albany Crescent - Both were together near the county line
shoreline but scoped from Buchanan.
One looked cleanly Eurasian, but one looked orange-faced but a bit dark at that
range, so I thought maybe a hybrid.
Tufted Duck and Barrow's Goldeneye (3 males) - Lake Merritt

Good birding,

Bob Power

Yard bird

Debbi Brusco <dgb_birding@...>
 

This is not the first time ever, but it was nice to see a Red-breasted
Nuthatch visiting the feeder in the rain on 11/20, along with the usual
chickadees and House Sparrows (which haven't been here for quite a
while). And today, it was back again, also pecking at the small old tree
the feeder is in.

Thanksgiving in Heather Farm--Walnut Creek

rosita94598
 

It was a relatively quiet morning in the park today, though the sparrows were happy to come out and have some morning seeds. I had a "Silent Spring" moment upon the realization that I was not seeing any Mallards. Maybe they were worried about John Madden stuffing them into a Turducken.

On the pond below the Seven Hills School, I saw 2 female Hooded Mergansers. This is a private school. Best viewing is from the corner of the Contra Costa County Water District property between the equestrian area parking lot and the pond. Also on this pond were 3 male and 1 female Bufflehead.

When I saw a single female Hooded Merganser on the large, mostly natural pond in the park on Monday, it was the first time for this species in probably 3-5 years. Admittedly, someone might have seen one on a day when I wasn't around.

Happy Thanksgiving.

Tufted Duck sighted today (Wednesday 11/23) at Lake Merritt. Seen in northeast
area of lake... between the bird sanctuary and the pergola (the columned
structure near the Lakeview Library in case you're not familiar). In fairly
sizable group of birds, including many Scaups.

Hi all,

I was wondering if anyone has any positive or negative reports of the
Slaty-backed Gull at Coyote Creek Lagoon or the Tufted Duck at Lake Merritt
since 11/19. Thanks!

Black-crowned Night Heron pic- MLK Shoreline

VN <verne_nelson@...>
 

Just an unusual photo of a Black-crowned Night Heron taking to its
wings. Up to three of them hunt the mudflats near Doolittle Pond
everyday at low tide (Martin Luther King Shoreline, Oakland, CA). They
are so patient, freezing in place and waiting tens of minutes for a
possible catch. Eventually, though, it's time to move on.

Albany & Berkeley waterfowl

John Cant 793-5216
 

Yesterday morning (the 22nd) there were a number of WIGEON at the base of
the Albany bulb including several that were clearly American and one male
Eurasian. A third bird puzzles me and I have posted photos at
http://www.pbase.com/johncant/ducks What might anyone think - is the
"question wigeon" American or hybrid? I would be grateful for opinions.



On the shore in Berkeley, next to University Avenue behind Seabreeze
restaurant were 3 ALEUTIAN CACKLING GEESE. These birds were a cautionary
note in the identification of cackler subspecies: one had no neck collar and
the other two exhibited faint thin collars. But head and bill shape fit
Aleutian very well. I assume the three were first-year birds.

American Kestrel

Other notable species:

American Pipit (small flock of 6+ birds)
Lark Sparrow (flock of 8+)
Green Heron
Sora (close views of it feeding)

Good birding,

Diving Goldeneye Hen Behavior at Lake Merritt

allenvhirsch@...
 

Saw a new behavior at Lake Merritt this afternoon. A diving hen put a clam or mollusk on her back without opening it (or even trying much first that I could see), swam a bit, and dove again, letting the clam finally roll off her back.

Sequence is here:

http://allenh.zenfolio.com/p325314033

Is this common? I assume it's because she couldn't open it, but I've never seen this behavior before.

GGAS Bay Cruise - Parasitic Jaeger at Berkeley Pier

Bob Lewis
 

Yesterday (Sunday) about 30 intrepid GGAS birders aboard the "Delphinus" under the guidance of captains Ronn and Barbara braved periodic rain squalls to tour the bay, including the Brothers, the Sisters, Alcatraz, the Berkeley Pier, Richmond Harbor and a number of other areas. We saw at least 4 Peregrine Falcons, one with prey, and at least two jaegers, one identified as a young Parasitic Jager near the Berkeley Pier. The bay was thick with grebes and Buffleheads, as well as a good number of Red-necked Mergansers. In spite of the weather, it was an interesting fieldtrip. Best sighting was probably a very intense rainbow that lasted at least an hour.

Probable Clay-colored Sparrow at Oakland Middle Harbor Shoreline Park (11/21)

Ken Schneider
 

I found what I believe to be a CLAY-COLORED SPARROW foraging at the base of one of the small poplars (?) along the long fenceline at the southeast end of the park this morning. I first found it foraging with a flock of White-crowned Sparrows, but then later it was on it's own. The bird was completely tail-less, having dropped all of its rectrices.

Here is my eBird description:

"Small, tail-less sparrow, dwarfed by nearby Zonotrichia, foraging at base of poplars along fence line at southeast end of park. Cream-colored unmarked breast, warm brown auriculars framed by darker brown feathers, thin whitish median crown stripe. Did not see back or nape well. Did not specifically note lores. Only got one poor photo of back of bird".

Although I'm fairly confident of the ID, I'd love to hear from anyone else who happens to see this bird. Of note, I again saw an immature GREATER WHITE-FRONTED GOOSE here this morning. The tide was very high during my visit - I did not see any unusual roosting shorebirds.

Tufted Duck, Cackling Goose -- Lake Merritt

Bob Power <rcpower@...>
 

Hi all,

At Lake Merritt in the afternoon, the Tufted Duck was easily found with 55
Greater Scaup in the Northeast arm of Lake Merritt. One male Ring-necked Duck
was hanging out by the east-most island near the nature center, and one Cackling

Goose was with a small flock of Canada Geese in the northeast corner of the park

adjacent to Grand Ave.

Good birding,

Bob Power
