Bar-tailed Godwit still at Emeryville 11/12

Edited

Thanks to Clay Anderson spotting it, Elizabeth and I got to see this bird which has now been here since October 31, essentially in the same location on the rocks south of the Marina office and west of the fire and police stations. Once found, the differences from a Marbled in size, coloration, and distinctive field marks are unmistakeable! It was a pleasure to show it to a later arrival and then to see that birder in turn point it out to yet another.

Tilden Park Gray-crowned Rosy-Finch not found today

David Quady and Nancy Boas
 

Birders:

Between Teale Friscoe and myself, the spot at which Horacio and Mona Mena found a Gray-crowned Rosy-Finch yesterday afternoon was monitored from shortly after 7:00 am until 11:00 am today …. without success.

Yesterday afternoon’s bird was found at 37 deg 53’ 32.3” N, 122 deg 13’ 51.6” W, very near a bench that honors Robert H. Blau . When Teale arrived this morning he took over monitoring that location while I moved north along the Seaview Trail about 300 m to a location that provided two benches, a picnic table, and what appeared to be micro-habitat similar to the discovery site: a local high point along the trail, with few trees blocking views to the east and west of the trail, and a broad swath of trail that lacks vegetation: perfect for a Rosy-Finch to forage on.

Looked good to me, but neither location held a Rosy-Finch.

Oh, well …..

Re: Great Horned Owl vocalization question

Bill Bousman
 

Dear Steve and Carol,

I think the shriek sound is similar to a begging call given by a juvenile bird, but at this time of year might not be expected (although I have heard typical Great Horned begging calls occasionally in the winter.)  I've been watching adult Red-tails harassing juvenile bird over the last two months, which is the natural way to force the youngsters out of the adult's territory. So, two guesses: (1) it is last year's juvenile using the begging call to elicit tolerance from the parent, or (2) it is a female being submissive to a male by using childlike sounds.  I've noticed many passerines using begging postures (wing fluttering) both as begging youngsters and as courting adults.  But this is speculative on my part.

We recorded these two birds in our backyard in San Ramon tonight about 6:30 pm (total darkness with moon rising).
One bird is obviously an adult Great Horned Owl.
But what's the other one shrieking?
Based on the fact that both birds were vocalizing in the dark and relatively near each other, we presume that it's another GHOW.
But we've never heard this vocalization, nor do we find much in the literature about it.
Any thoughts or opinions welcome.

Re: Cassin's Finch at Tilden Botanical Gardens

Alvaro Jaramillo
 

Lee et al.
That does look like a Cassin's Finch. Very good find. Note first that the co-finder of the rosy finch is Horacio Mena, not Hortacio. But also note that the Rosy Finch is a "Hepburn's" Rosy Finch from much farther north, not a Sierra bird. You can identify it by the extensive gray on the face. This bird has come from the north, not from the East. The arrival of the Rosy Finch and Cassin's Finch may have no correlation at all.

Subject: [EBB-Sightings] Cassin's Finch at Tilden Botanical Gardens

Birders,

This morning at approximately 10:30AM, I saw what I believe to be a Cassin’s Finch at the Tilden Botanical Gardens. It was sitting on a tree top near the center of the Garden. It had the distinctly red crown much brighter than any other part, pink wash on throat and upper breast, whitish lower breast and belly with barely detectable streak marks, notched tail. This species is known to mix with other montane finches like the Red Crossbills and Pine Siskin reported here yesterday by Erica Rutherford and John Colbert. I don’t think it’s an accident that today Dave Quady reported a sighting (by Mona and Hortacio Mena) of another mountain bird the Gray-crowned Rosy-Finch on Tilden’s Seaview Trail. Something is pushing these birds our way this year. A photo for id purposes of the Cassin’s Finch is attached to my eBird report:

Gray-crowned Rosy-Finch in Tilden Regional Park, 11 November 2019

David Quady and Nancy Boas
 

Birders:

About 3:30 this afternoon Mona and Hortacio Mena found and photographed a Gray-crowned Rosy-Finch in Contra Costa County. It was in Tilden Regional Park, on the Seaview Trail, near the Upper Big Springs Trail, at these coordinates: 37 deg 53’ 32.3” N, 122 deg 13’ 51.6” W.

They added, "It was on the trail foraging for a good 5 minutes, until it got flushed out by folks. We were able to get pretty close to the bird.”

Here is a cropped version of their photograph:




What a find!!

Hi Birders,

As of 3pm, there is a single Cackling Goose mixed in with the Canada Geese on the pond at Oak Hill Park in Danville. Haven't seen one in few years, and always surprised at how tiny they are compared to the big guys.

Happy birding!

Black and White Warbler Continuing

Just updating that several of us saw the Black-and-White Warbler again this morning about 9:30 am in the two minimally leafed trees south of 2999 Regent where it dead ends in a turnabout. When last seen the bird was flying south to another group of trees. Thanks again to Sharon Jue for the tip. Wonderful bird.


South Berkeley Killdeer Overflights at Night

Linda T
 

We've been repeatedly getting Killdeer flying over at night calling over the last week or so. A couple of times we could hear only a single individual, but the last couple of times there has been a group. Their familiar call is incongruously named the "visual display call" in the new Sibley app. Last night they were here at 10 pm, tonight it was 6:30 pm. We are more or less equidistant from Leconte Elementary, Willard and the fields near Sports Basement though we've never seen nor heard the birds in our part of town.

Anyone know more about these night flyovers?


miscellanea

Ethan Monk
 

Hi all,

Got out to a few spots today. Don't have much to report that hasn't already been said, just a few quick things.

Birded Jewel Lake today in Tilden from about 750-9. I was hoping for a good showing of flyover finches as the fog broke, but I was clearly in the wrong place. The ridges on either side of me seemed to have a few flyover finches? Anyway, the best thing that came of this was a heard only flock of Crossbills that at around 830am seemed to fly North to South down the valley. It sounded like there were about 5-7 of them, but they were fairly distant. Crossbills are putting in a good showing this year and I'm sure enough searching in Tilden/Redwood Regional should find us a few flocks actually down and foraging, maybe flocks that will be chaseable? Who knows

I spent too much time at Alta Bates medical this morning for my liking. The Black-and-White Warbler was a no show for 40 minutes of 4 of us walking Webster, Regent, Ashby and a few neighboring streets. Finally someone (Bill Clark I believe?) checked Colby Street and there it was, just South of the emergency ambulance loading zone. So just take note that the warbler moves around now a little more than it did previously.

Skipping ahead, checked the Point Richmond Neighborhoods today. Mainly Western Dr., Santa Fe Ave., and Lobos Avenue. Coverage was minimal. There was a White-throated Sparrow on the start of the Santa Fe Avenue Trail, and a flyover gull that to me seems a Glaucous x Glaucous-winged Gull. Glaucous is possible I guess but the bill seemed a little too messy. These neighborhoods seem really good for wintering neotrops and such and I think are worth checking throughout the winter.

Western bluebirds in Albany

Richard Sintchak <rich815@...>
 

Flock of about 20-25 Western Bluebirds just flew over my rooftop garden in Albany near the corner of Solano Ave and San Pablo Ave and landed in a tree across the street. One beautiful male, slightly separated from the group, landed on the eave of my roof not 10’ from me and did a call/response with the flock a few times while looking down at me and seemingly checking me out. Then they all flew off heading east. Not rare but a nice Saturday afternoon visitor in such an urban environment. :-)

Hi Hugh,

The Bar-tailed Godwit was found at high tide (~9:30AM) today by the Golden Gate Audubon field trip among the roosting shorebirds near the Royal Coffee on Powell Street. So it’s still hanging around for anyone that’s interested.

Rosita and I saw the bird on the east side of Alta Bates Hospital with others about noon or 12:30 today. It was in some trees behind the hedge and in front of the hospital building, pretty much across from the Webster Street intersection with Regent. Thanks to Alan Howe who showed me where it was after I had been hearing it for several minutes.
Rosita and I then drove to Emeryville to try and find the Bar-tailed Godwit, which we saw lat week. We did not, but Rosita found a female-type Surf Scoter on the rocks with lots of Willets and Surfbirds. Unfortunately, the Scoter had some fish line tangled around the head. There was no way to capture this bird without scaring all the others off the rip-rap, and probably the duck out onto the water.
