Bar-tailed Godwit photos

Mark Rauzon
 

The Bar-tailed Godwit (re)located by Steve Tucker this am at Middle Harbor Shoreline Park was eventually cooperative, once Pat Bacchetti, Mark Eaton and I teased it out from the dense flock of waders by noting its relative whiteness, even a shade lighter than the Willets. We also noted its face is stained buffy and wondered if this happened during it's South Bay stay, if it is the same individual, for the Bodega bird appeared stain-free. The banging of a container got all the bird to look up, while R&B music wafted over from the picnic area. I love it when rare birds visit Oakland!

Smashing views of the Bar-tailed Godwit at 3 pm as close as you want.   The flock of 100+ godwits have been shuttling back and forth between the short jetty and the sandy beach 100 yards to the north.  Thanks, Steve.

Yesterday along lower Mines Rd. - (the first four miles). I was surprised to find 25 Yellowbilled Magpies.

They were in three family groups.

 I did not find a single or even a pair of YBMA.

 Also present was a Golden Eagle, a Prairie Falcon, a Cooper's Hawk, several Red-tail Hawk's, Red-Shoulder Hawk and many Acorn Woodpecker's.

Enjoy the weekend and great weather,

MacGillivray's Warbler in Emeryville

Noah Arthur
 

This morning I stopped by the tiny, shady poplar grove behind the Chevy's in Emeryville (on Access Rd., at the "base" of the Emeryville Marina peninsula). The first bird I heard, then saw, was a first-fall female type MACGILLIVRAY'S WARBLER. The bird popped out of the hedge on the south side of the road in response to pishing, then flew up into the blackwoods and poplars! Never seen a Mac do that before... But got some photos to confirm the ID, and sure enough that's what she was. Later in the morning, after a hot, sunny, and uneventful wander around Albany Hill, Jack Hayden and I returned to the poplar grove and briefly re-found the Mac -- once again flitting from the hedge up into the trees. Other migrants in this very birdy little grove were several YELLOW WARBLERS, a WILSON'S WARBLER, a HUTTON'S VIREO, and a PACIFIC-SLOPE FLYCATCHER.


Bring on the warblers!

Parasitic Jaeger Emeryville

Jim Chiropolos
 

The big elegant tern colony roosting on the Emeryville crescent has drawn some interesting birds. A Parasitic Jaeger was chasing an elegant tern flashing its white wing patches. Best viewing, Emeryville Marina look towards Angel Island.


Morning is the time to look with the sun at your back. Evenings would be quite difficult looking into the sun.


Good Luck,

Jim Chiropolos,

Re: SWAINSON'S THRUSH

Bill Bousman
 

Dear Sylvia and EBB,

Just to add my two cents. The "Birds of Northern
California" is an amazing resource and has more
than stood the tests of time since its
publication. Just to emphasize what Joe said,
the Swainson's Thrush bar graphs on p. 58 shows
this thrush in two roles. The first is its role
as a breeding summer resident in the wet coastal
forests and mountains of northern California and
the second is as a passage migrant both through
areas where they breed and areas where they do
not. If you live on the wet bayside coast of
Alameda or Contra Costa counties where these
birds breed, then the first bar graph is your
best guide, otherwise, the second bar graph will show you when to expect them.

For what it's worth, at the Coyote Creek Riparian
Station near Milpitas, we banded 2458 Swainson's
during the spring passage from 1986-1996 and 1996
Swainson's during the fall passage for those same
years. This is a location where this thrush has
not nested in a hundred years, so these are all
passage birds. For the fall passage the 5th
percentile date for these records was 3 Sep and
the 95th percentile date was 13 Oct (that is, 90%
of all birds came through between 3 Sep and 13 Oct).

Re: SWAINSON'S THRUSH

Bob Power <rcpower@...>
 

Sylvia,

This may or may not be helpful, from PRBO's species account (yes, I know -- Pt. Blue).

Departure date from breeding grounds: According to McCaskie (1988), departs Coast and Mountain regions late August through October. PRBO banding data for Marin County (1996 and 1997) -- latest capture dates October 16, 1996 and October 4, 1997.
 
Spring and Fall migration period: While SWTH is rare in Interior and Basin regions during the summer months, abundance peaks in Spring (April through May) and Fall (August through September) in these regions (McCaskie 1988) -- possibly indicating peak of Spring and Fall migration period in California.
---------

And at the same time, we're on the front end of Hermit Thrush arrival dates.

Best regards,

Bob Power

Baird's Sandpipers at Waterbird Park, Martinez

Judith Dunham
 

I plead guilty to putting sightings on eBird and not posting. So I'm going to engage in some behavior modification going forward.

Six East Bay birders stopped at the park when returning from Napa. We birded from the main parking lot, then went to the west side of the park via Arthur Avenue off I-680. We parked at the first pullout on the service road leading north, then walked to where we could see the south end of the water. Scoping the shoreline and inlets, we found four BAIRD'S SANDPIPERS, then discovered a fifth when scoping from the wood overlook near the tunnel to the plant. The birds were there around 11:45 and remained when we left about an hour later.

Wilson's Warbler - Antioch yard - 3/31

Yesterday (8/31/2016), we had good looks at a male Wilson’s Warbler that was drinking from the dripper at our bird bath. We also had a Wilson’s Warbler in the yard a week ago.

Good birding

Baird's Sandpipers, McNabney Marsh, Martinez

tracy_farrington
 

Hugh Harvey and I, after a bit of searching, were able to get a decent look at four BAIRD'S SANDPIPERS on the east edge of the south end of McNabney Marsh (Waterbird Regional Preserve), Martinez. This viewing location is accessed from the service road to the Mt. View Sanitary District offices.
After you pass through the gate at the end of Arthur Rd., park along the narrow asphalt pull-out on the right. Do not park on the grass shoulder. Walk north a hundred yards until you have a clear view of the water. For those  unfamiliar with this marsh, here's a Google Maps link: https://goo.gl/maps/XhecUQwoBKS2

The four birds were scattered among just a few Western Sandpipers allowing for an ideal contrast in size, bill shape and overall color tone.

Good birding,

Possible Calidris ferruginea in CoCo County

albertlinkowski
 

I've just got hopeful respond opinion from Pete Dunten, Contra Costa eBird reviewer about interesting Calidris, whose I observed recently in Waterbird Preserve in Martinez (see eBird checklist with description of the individual) and Pete's comment)
I would like to add a few more details, which can be helpful in identifying the Calidris but not well seen in my poor quality photos ..... breast is washed with warm orange/peach; rest of ventral white without any markings on belly or flanks, legs definitely black and relatively long.

Is this indeed Curlew Sandpiper?, or something else?. All comments and opinions welcome

California Quail chicks - very late brood?

wespey
 

Yesterday, August 28, we had two adult California Quail and six very tiny chicks in our backyard in northeastern Lafayette. It was impressive to see the two adults acting as lookout and guardian. It seemed that one would take a high point and watch the perimeter while the other adult coached. When first observed about 5 pm we could see that one of the chicks was lagging behind and not alert and responsive as the others were. About 6 pm we saw a chick flopping on the ground and clearly in great distress. By 6:30 it was dead. The dead chick's torso was only 5 cm long.

Today the two adults and the remaining five are back, working the same ground.

Is this late in the season for such a hatch?

Yesterday evening while walking around the Main Marsh at Coyote Hills RP, I saw my first Pectoral Sandpiper of the year.
It was foraging with Yellowlegs near the edges of the Marsh.

Contra Costa birds Sunday August 28

rosita94598
 

Rosita took a walk to Heather Farm after 5 PM and then called me.  She had a small duck and a sandpiper at the large, mostly natural pond.  It was a Spotted Sandpiper on the rocks along the island edge when seen from the large oak on the west side.  The duck was mixed with some Canada Geese by that time.  I studied it quite a bit, and it appears to be a juvenile Green-winged Teal.  It is mostly colored like the average female duck, but is small, has a black bill and a bit of a buffy streak under the tail.  It never opened its wings.

Earlier, I met Stephanie Woods and her husband, Ken, along the bike/walking trial west of the Olympic/Reliez Station Road intersection.  They were too far west for the normal location of the Western Screech-Owl which has been reported since February.  I told them to meet me farther east along the wooden railing, and sure enough, the owl was in its typical spot about 15 feet up in an oak tree.  Chick wrote me after I was home and admitted he was not a botanist/arborist.

Re: Screech Owl in Lafayette

We live near there and my wife has seen the same owl two times.  The last was with my sister, and they were watching the tree right at dusk, when suddenly, the owl left the tree and flew very close to them.  They were awe struck.
