Hi Bruce,

 

I’d like to report a tropical kingbird I observed at Hoffman Marsh in Richmond at approximately 10:45 am Thurs. Oct. 29. It was perched for about 5 minutes on top of a bush across the slough along the path that leads from the Bayview Ave. entrance to the Bay Trail about 50 yards east of the bridge across the slough. At first I identified it as a western kingbird because of the bright yellow breast extending almost to the neck. However on studying videos and reading field reports, I changed the identification to tropical, in part because I saw no white edge along the tail and also because tropicals are occasionally seen along the California coast from Sept. to Nov. Unfortunately, when I made the observation, I didn’t record the bill size, which is an important diagnostic of tropical vs. western. I reported the observation to ebird and was queried about how I eliminated Cassin’s. I noted that the yellow extended to far up the breast for Cassin’s. I’d be thrilled if other birders confirmed the observation.

 

Thanks.

Re: Tilden Red Crossbills by Nature Center

Lee Friedman
 

I watched the Red Crossbills for about one hour this morning 11AM-noon. They were still in the same location, near the top of a tall pine behind the Nature Center. The Pine Siskins seemed to keep to the adjacent tree. I observed the same flight pattern that others noted—every few minutes, they would fly off as a group of 15-20 and then return a few minutes later. However, one time they flew off as group and I got a pretty good count of 35, making me realize there were likely two groups in the tree at one time (grouping perhaps like Cedar Waxwings do).

 

Because they stayed quite high up, perhaps 70-100’, it was difficult to photograph them. My clearest photos are of the (red) males that occupied the very top of the tree; the (yellow) females stayed a bit below with some juveniles. Here are two photos of the male Red Crossbills:

Re: Tilden Botanic Garden - Swamp Sparrow 10/31/15

While biking todayI made a quick stop around noon at Tilden Botanic Garden to see if I could find the Swamp Sparrow.  Wasn't successfull, but in the process caught a quick glimpse of what I thought was a Wilson's Snipe scurrying off out of site in the creekbed,  I hung around a little longer and eventually it came waddling back, prodding for lunch. That's probably the most confined area that I've ever seen a snipe.
 
Made another stop near the Grizzley Peak/Skyline intersection when I heard a Hairy Woodpecker and in the process of locating it also got some great looks of a Golden-crowned Kinglet low on a tree below the road.  Also in the same tree were a few Pgymy Nuthatches.

There were several Song Sparrows in the vicinity as well. Some ID pictures are embedded in my eBird checklist: http://ebird.org/ebird/view/checklist?subID=S25643811 .

Earlier I and a group of other birders were treated to the continuing RED CROSSBILLS in one of the redwoods behind the Education Center. At one point they were all flushed from the tree by an incoming Acorn Woodpecker, and my rough count of the flock was 60-80, but that was probably an undercount. There were several flocks of PINE SISKINS in the area as well. One HOODED MERGANSER remained on Jewel Lake. Several of us watched it catch a fish and take several minutes to maneuver it into swallowing position.

Crossbill in Strawberry Canyon

Bruce Mast
 

Seeing an eBird report of Red Crossbills at the UC Botanic Garden yesterday, I went out this morning to see if I could replicate the feat. Arriving around 7:30 am, I birded around the parking lot about an hour until I heard and the saw a flock of about 20 birds flying around the lower canyon. A lone female flew up and perched in a nearby conifer, giving me good scope views.

Bird on,

This morning I found a Swamp Sparrow about 40 yards east of the Springtown Blvd bridge. This bird is difficult to see and generally stays out of sight. Many Lincoln's, Song's and Savannah's are also present.

Tilden Crossbills continue

The crossbills and pine siskens continued this morning in the vicinity of the nature area Visitors Center. They were in and out, gone then back, gone and back at the top of various Redwood trees. Best vantage point to monitor the flyabouts and alightments is behind the center. Nothing in Jewell Lake.

Ardenwood

Matthew Dodder
 

Folks,

Yesterday afternoon I made a quick stop at Ardenwood to see the LEWIS'S WOODPECKER in the Northwood portion of the park. It was easily relocated in the bare branches of the tallest eucalyptus trees bordering the orchard. Also present in the  E-I-O PICNIC AREA was a RED-BREASTED SAPSUCKER. WESTERN BLUEBIRDS, CEDAR WAXWINGS and of course many YELLOW-RUMPED WARBLERS were there as well. The farmhouse and the fountain was active with PINE SISKIN, AMERICAN GOLDFINCHES, HOUSE FINCHES and YELLOW-RUMPED WARBLERS. HERMIT THRUSH was almost abundant in the wooded section leading back toward Southwood. The pumpkin field contained a good number of TRICOLORED BLACKBIRDS as well as RED-WINGED and BREWER'S BLACKBIRDS.

Hayward Shoreline

Matthew Dodder
 

Folks,

I led my Palo Alto Adult School advanced birding class to Hayward Shoreline on West Winton yesterday. We had several highlights including a BURROWING OWL along the channel leading out from the parking area, a pair of COOPER'S HAWKS in a dispute, at least two NORTHERN HARRIERS, a MERLIN (columbarius) near the footbridge leading to the marsh, WHIMBREL several RUDDY TURNSTONES and a couple of BLACK TURNSTONES on the breakwater south of Frank's Dump. We were also fortunate to view RIGEWAY'S RAIL in the marsh as it made its way along the edges.

The overlook was filled with WESTERN MEADOWLARKS, AMERICAN PIPITS and a few HORNED LARKS, but it was difficult to get a good look as they passed through the grass.

On the bay were FORSTER'S, ELEGANT and a single COMMON TERN, an OSPREY and all the GREBES except Red-necked. Frank's Dump was essentially empty when we arrived, but as we left, it began to fill up with thousands of Shorebirds that streamed in over our group. Quite a beautiful sight!

Crossbills and Tropical Kingbird

Bill Clark
 

The Red Crossbills continue at Tilden, as easy walk up birds:

At MLK Shoreline (Arrowhead Marsh), the Grasshopper Sparrow was not seen at 8am, 2pm or 3:30pm.  He may be gone.
But there was an American Pipit.  And my first Tropical Kingbird!  He was on the fence as your left as you leave the parking lot.

Finally, here's a photo from the Lewis's Woodpecker sighting I posted earlier at Ardenwood Farm:

Semipalmated Sandpiper at Coyote Hills

Julio M
 

This morning (10/31, 9:30 AM) at the Coyote Hills No Name Trail leading to the NWR I found a dark-legged peep which looked good for a Semipalmated Sandpiper (SESA).  
The bird was on the right hand side of the trail leading into the Bay and approximately 30 meters past the pump house.
The bird was the only small peep with dark-colored legs among the abundant Least Sandpipers (LESA).
From my vantage point it was approximately the same size as the nearby LESA but with grayer plumage and with a cleaner white throat.
One of my pictures shows partial webbing between the middle and outer toe.
I don't recall seen a SESA this late in the California fall season.

Red Crossbills at Tilden Nature Area Friday 10.30.2015

Alan Kaplan <lnkpln@...>
 

Friends!

Thanks to Anthony Fisher for the notice about the Red Crossbills behind the Environmental Education Center at Tilden Nature Area, and to Chris Kondakian for the great view of them today!

Chris and Ted K. were already at the site when I got there around noon, and we saw a Sharp-shinned Hawk with a hungry eye on the crossbills, and the visitors left in a burst of flight, but returned throughout the next two hours.

Has anyone proposed what Flight Call type these might be? My experience with these is limited to one morning with Steve Glover in the TNA parking lot, him looking up and saying “Red Crossbills” as a flock came over at both great height and speed!

Best of Boids!

Alan Kaplan


Red Crossbills Continue

Doug Mosher
 

This morning (10/30) in the tall tree behind the Tilden Nature Area's Ed Center staff lot. Mingling with a flock of Pine Siskins and feeding on the pinecones. At least 15 males and females.

Ran into David Moore at Arrowhead Marsh this afternoon, about 30 minutes before high tide. He pointed out the Grasshopper Sparrow that was feeding in the dirt area on the side of the path opposite the water. The bird was very cooperative. Dave asked what my closest focus was and he wasn’t kidding - it practically climbed in my pocket - coming about 4 feet away at its closest.

In addition to the Grasshopper Sparrow, there were at least 2 Ridgeway’s Rail and 1 Sora, in addition to the waders having out on the still closed pier.

There is a link to the photos including one I shot with my iPhone to show how close the bird came.

Evening Grosbeak in Walnut Creek

fgsafier
 

At about 9:30 this morning I was coming home from Heather Farms, when I observed an unmistakable male Evening Grosbeak calling, perched at the top of a bare conifer. It was along the canal trail, just west of the main Walnut Creek (the creek, not the town) crossing.

sora, common yellowthroat at Arrowhead Marsh high tide

allenvhirsch@...
 

High tide on the 28th produced a sora or two out in the open, including one that flew from one cluster of reeds to another. I wouldn't usually display an image with the bird flying away from me, but for a sora, I made an exception (since I've never caught one in flight before):

I also photographed a common yellowthroat female at the same high tide.
