Common tern at Elsie Roemer

Teale Fristoe
 

Hello all,

I'm currently at Elsie Roemer bird sanctuary on Alameda island, where I've
been watching a first year common tern among the many elegant, least, and
Forster's terns. I'll share a photo when I return home.

Happy autumn,

A photo of the Common Tern can be seen on my ebird checklist:
https://ebird.org/view/checklist/S58945114

When I saw the Tern, it was on the peninsulas southeast of the observation
platform, about in line with the end of the fence. It seemed to be
associating more with Elegant Terns and Black-bellied Plovers than
Forster's Terns.

Black Skimmer in inland Northern Contra Costa co.

albertlinkowski
 

Today, 14th August. 2019 in the evening I found juvenile Black Skimmer at Waterbird Regional Preserve in CoCo County (in Pacheco east of Martinez) As you might known, this is a rare bird for county and very rare
for inland part, and as a matter of fact this is only the second county inland record and now farthest one.

Found on largest (grassy) islet of Waterbird Marshes, seen from Preserve parking lot.

Last time the bird was seen at 19:57 in the evening, still roosting on the islet, there is a good chance that he/she will stay at least until tomorrow morning.

To get to Waterbird Regional Preserve (in eBird nomenclature Waterbird Regional Preserve (including McNabney Marsh)) take fwy 680 North, and take last exit before toll bridge, take right into Waterfront rd,, and then another right into Waterbird Way, entrance to reserve parking lot is on the right side of the road.

On another note, there is currently Mute Swan family still present on marshes (breed there), you may encounter parents and their seven full grown (but still mostly brown) cygnets, male however is rarely seen together with the rest of family, usual can be seen rather alone. Near this place, at Mococo Rd, Pond, there is another family of Mute Swans, family of 10, two adults and eight full grown cygnets (still brown though).

Thanks to Albert Linkowski for the tip on the Black skimmer at Waterbird Regional Preserve! We went this morning and saw it as well. It was still at the southern tip of the large grassy island, at the northern end of the marsh. Best seen from the parking lot for the Preserve. It was among a group of cormorants, Black necked stilts, and two Caspian terns. Fortunately, Hugh showed up as well, so we could see it through his scope! It was too long of a stretch for 10x42 binoculars.

The skimmer is now in the same location as noted above.

Northern pygmy-owl at Valle Vista yesterday

Kathryn Spence
 

I found a Northern Pygmy owl at about 9:30 a.m. yesterday along the Riche trail. It was being verbally harassed by an Orange-crowned warbler, 2 Western bluebirds, an Oak titmouse, a Hutton’s vireo, a Ca Scrub jay, and 6 hummingbirds- hard to miss.

I watched it for about 15 minutes. Small size, yellow “staring" eyes, false “eyes" on back of head, brown streaks on white chest, little ball shape with tail sticking off to the side. It was on a snag in a partly dead tree near 4 orange traffic cones about 1/3-1/2 way down the Riche trail from the parking lot.

I alerted the Audubon group that was visiting there today but I think it had left by the time they went looking for it.

Eden Landing 08-14-19 (Alameda County)

Matthew Dodder
 

Santa Clara Valley Audubon Society was treated to an incredible tour of the historic Eden Landing Salt Works and Snowy Plover survey area by SFBBO’s resident expert Ben Pearl this past Wednesday.

During the three mile in the sun and heat, Ben discussed the techniques used to band and monitor the threatened birds. He explained the pressures that have led to their decline, including their predators as well as changes to their habitat. He then led us to a restricted area where we observed many Snowy Plovers and their adorable puffball chicks! We learned about the history and the importance of this fragile and complicated area, and the work being done to protect the birds. It was wonderfully informative!

https://ebird.org/view/checklist/S58989441

We look forward to another visit to this area next year to check in again with Paul an the Snowy Plovers!

Elsie Roemer Terns

Teale Fristoe
 

Hello,

Today I went back to Elsie Roemer Bird Sanctuary. After looking
unsuccessfully for rare shorebirds with Noah Arthur, I started examining
terns. There were far fewer today than there have been my past couple of
visits, with just one Least, two Elegant, a handful of Forster's, and no
Caspians. But there were a couple of interesting individuals present.

The first was an adult Common Tern, which was fairly cooperative and stood
next to a Forster's, allowing close comparison of legs and bill. It
apparently had not started molting and had a complete black cap and nape.

I'm still not sure on the species of the other individual, and I welcome
any thoughts you may have. It first struck me as a juvenile Common because
it has black outer tail feathers and a black nape, but the wing pattern
doesn't look right for a Common. I then thought it might be a stray Arctic
(hey a guy can dream, right?), but the bill looks too big for that. It also
appears to be molting, which I believe only an adult would be doing at this
time of the year. So I now think it's probably a Forster's, though I don't
know how to explain the outer tail feathers.

Photos and a complete list can be seen on ebird.
https://ebird.org/view/checklist/S59118513

Again, I'd love to hear feedback on the id of the mystery tern if you're so
inclined.

Happy migration,

Re: Elsie Roemer Terns

Alvaro Jaramillo
 

Hi Teale,
I think the mystery tern is a subadult Forster's Tern, maybe two years old? The reason is that the mask actually shows through as being darker than the nape in one photo. But more importantly in one of the photos (the second one), the longest tail feather shows a dark edge on the inner vane of the feather. This is unique in mid-sized terns in North America, all others show a dark edge to the outer vane. There is some odd dark on the base of the tail, but I am ignoring that, as the dark inner vane on the longest feather is so key. Common Terns at this age often also have the dark on the leading edge of the inner wing (patagial/carpal), although it is less consistent by the second year.
Good birding,
Alvaro

Is Blue-gray Tanager Extirpated from Ebird?

Dave Weber
 

When viewing all of my photos in Ebird, I noticed that Blue-gray Tanager is
missing. This is the bird seen at Sycamore Grove Park/Arroyo Entrance this
year.



I found the following:

It appears on my single checklist with the photos.

It appears on my county list.

It does not appear on the full county checklist.

I cannot find anyone's photos of the bird, ie the search returns no result.

Other exotics still appear on the county list.



Has anyone else noticed this or is it just me?



Dave Weber,

Milpitas

Re: Is Blue-gray Tanager Extirpated from Ebird?

Frank Fogarty
 

eBird protocol for most introduced species (with a handful of exceptions)
is for reviewers to invalidate the record with the flag
"introduced/exotic". This removes the records from all public output,
including maps, but they are still present in the dataset and visible on
the individual checklists. I've heard that the rationale for this protocol
is to reduce the clutter of introduced species on bar charts, although that
seems pretty trivial and I'd like to see introduced species included in
public output.

If anyone is interested in analyzing records of a specific introduced
species, it's relatively easy to get these invalidated records in the eBird
Basic Dataset download.

https://groups.io/g/EBB-Sightings/message/12346

But much of the discussion was on the discussion list starting at:

https://groups.io/g/EBB-Discussion/message/57

The bird was originally found by Dean LaTray on 5 April posted on eBird:

with many follow up eBird posts some containing outstanding photos. Here is
a partial list:

Contra Costa sightings

rosita94598
 

We have been seeing an adult and a young Common Gallinule at the mostly natural pond in Heather Farm Park.  This is in the Ygnacio Valley of Walnut Creek.  Also there for the last week or so are two Pied-billed Grebes, one of which is less than adult.  Most days there is some combination of waders, either Green Heron, Snowy Egret, Black-crowned Night-Heron or Great Blue Heron.  Up to 5 Killdeer have been seen on the ball fields across from the pond.
This afternoon at McNabney Marsh adjacent to I-680 in Martinez, the previously reported Black Skimmer was still present.  It prefers the flat, grassy island best seen from the parking lot at Waterbird Park at the northeast corner of the marsh.  A scope is helpful.
Midway south along the marsh is an Osprey platform, which was erected by Mt. View Sanitary several years ago.  Today I saw two Ospreys sitting in attendance at the platform.  This is best seen from the viewing platform along the entry road to Mt. View Sanitary at the south end of the marsh.  Also at the south end were 7 Pied-billed Grebes and 5 Killdeer.  Lots of Mallards were scattered throughout the marsh and at the north end a number of Dowitchers, Stilts and Greater Yellowlegs.
At Waterbird Pond farther east on Waterbird Way and at the entrance to Acme Landfill, I counted 54 Black-necked Stilts.  It was well over 90° when I was out there and did not realize that my tee-shirt was becoming wet with sweat until I was leaving the landfill entrance.

Good godwit at Franks Dump

Noah Arthur
 

The unusual godwit that was reported with distant photos on Facebook yesterday, was back in Franks Dump this evening along with hundreds of Marbled and Willets. It’s definitely one of the exotic ones and looks to me like the same Bar-tailed that’s been kicking around the Bay Area the last few falls. However, I know next to nothing about distinguishing one rare godwit from another, and some people commented on the original FB post saying they thought it didn’t look like a Bar. I put it in ebird as such bUt will edit if needed...
Also present were TWO (yes two) PACIFIC GOLDEN-PLOVERS. 
Good shorebirding!
Noah Arthur (Oakland)

Godwit photos

I've added some photos of the apparent BAR-TAILED GODWIT to my eBird list... https://ebird.org/view/checklist/S59188688
I'm pretty sure now that this is a Bar-tailed and not Hudsonian or Black-tailed, due to the shaft-streaked upperparts.
