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!

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

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.

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.

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).

Re: Common tern at Elsie Roemer

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.

California Thrasher at California Trail Oakland Zoo

Jone Taylor
 

While visiting the beautiful California Trail at the Oakland Zoo, I watched a California Thrasher and juncos run out of the shrubs and forage left over bread crumbs and French fries under the empty tables in the late afternoon. They also did a little foraging under the bushes too. I was surprised they had developed a taste for junk food!

Mt. Diablo Audubon trip to Frank's Dump August 5

rosita94598
 

For a glorious end to another day in the paradise, 18 participants made a late walk to Frank's Dump at Hayward Regional Shoreline and were not disappointed.  Shorebirds were thick, concentrated by the high tide which pushed them off the edge of the bay.  Willets, Marbled Godwits Western Sandpipers and Black-bellied Plovers predominated, but we also had lots of Red Knots, plenty of California Gulls, a few Short-billed Dowitchers and three Red-necked Phalaropes.  A single Ruddy Turnstone was seen by some, 2 Caspian Terns and single Western and Ring-billed Gulls were also present. But a big surprise was 4 Black Skimmers flying north over the bay as we were walking back to the cars.  With other birds seen while walking, our list finished at 38 species for the evening.

Warbling Vireo

judisierra
 

An unusual (possibly a first) for me yard bird showed up yesterday, a warbling vireo. It bathed similar to a hummingbird- skimming across the water. Later it stuck around and was foraging in it's usual manner in my neighbor's alder tree.

Odd Cal Towhee query

judisierra
 

I had a Calif. Towhee in my yard yesterday with what at first looked like a black eye. On closer inspection it looks like most of the right side of the face was dark gray and that the feathers were missing. There was a distinct edge and depth difference along the edge with normal feathers. I ruled out wet feathers, and melaninistic spot. Anybody have ideas of what caused this?

Re: Unusual Raptor Sighting at Albany Bulb

Ken Copen
 

Hi Annie, that is from my perspective, an adult Peregrine Falcon
Dark hood, dark wings, yellow cere with a darker bill tip. The only part that is a little unusual is the barring on the chest is very light. I have seen that, I took a pic of one in Moss Landing that had almost indistinct barring like this one, it could also be the lighting to some extent as well.

hopefully can provide enough detail to identify the bird.

By all accounts it looks like a Short-tailed Hawk. I know how very unlikely
this is. In flight it was extremely aerodynamic and flew more like a falcon
than a hawk. Thank you for any help that you can provide.

Golden Plover at HRS, Frank's Dump

Eddie Bartley
 

The Cal Academy/GGAS Master Birding class had some very nice shorebirds this afternoon at Frank's Dump in the HRS.

An adult GOLDEN PLOVER was spotted mixed in with a large group of Red Knots and Black-bellied Plovers. Almost certainly a Pacific but it was in mid-molt and we never got definitive views of primaries, etc. Will add documentary photos soon.

By the time we arrived to Frank's Dump shorebirds were packed on the sandbars making counting difficult but numbers appeared to be up on many of the species compared to recent eBird lists in any case. Both Turnstones were about as well as at least one Surfbird. We had at least 90 Red Knots (!), 400+ Western Sandpipers, 300+ Marbled Godwits, 150+ Willets. etc. While never numerous 8+ Snowy Plovers seemed better than what I remember at this site. One tern deserving another there were at least 6 Least, 4 Caspian Terns. Great fun!

Happy Trails!

Group Guidelines #guidelines

EBB-Sightings@groups.io Group Moderators <EBB-Sightings@...>
 

Thank you for being a member of East Bay Birding-Sightings. This is our monthly reminder sent to the list with information about the group.

East Bay Birding-Sightings is a list intended for reporting interesting and rare bird sightings in the eastern San Francisco Bay Area. It is not a general discussion list or place for posting classes, trips, etc. For that we have established East Bay Birding-Discussion.

No photos or attachments can be sent with sightings messages. To share a photo, post it elsewhere and include a link to it in your message to the group. eBirders often use a link to their sightings reports which include photos. Some members have joined the East Bay Birding Affiliated Flickr group, where discussions are also encouraged.

We've been asked to remind list members of various aspects of birding ethics, may which include refraining from posting locations of nests. This topic could be usefully explored further on East Bay Birding-Discussion.

East Bay Birding-Sightings is affiliated with Mt. Diablo Audubon, and members of this list are welcome to attend the monthly program meetings in Walnut Creek. MDAS also offers classes and field trips around the region, so if you're interested in learning more about birding in the area or joining other birders in going out birding, the Chapter can help you find an outing that matches your interests.

If you ever need to unsubscribe from this list, an unsubscribe link is at the bottom of every message, or you can go to https://groups.io/g/EBB-Sightings/. That's also where you can view the list archives, set up a vacation hold, change your email address, or modify your subscription in any way.

Golden eagle at Valle Vista

Wendy Parfrey
 

A juvenile golden eagle is just now catching a thermal over Valle Vista parking lot while being harrassed by a RTHA (which looks tiny in comparison). Lots of white on base of tail and primaries. Beautiful bird.

Golden Eagle flies over Hercules again

Susana dT
 

We were having lunch outside and heard angry Red-tailed calls. I thought something was chasing it but they (2 red-tailed hawks) were the ones chasing a golden eagle. The video is shaky but you will be able to see the golden eagle dropping heavy artillery on the red-tailed escorting it out towards Crockett Hills where it belongs.

Common Tern Ballena Bay

Patricia Bacchetti
 

Today at 1 PM, just after high tide, Judith Dunham and I saw an adult Common Tern on the breakwater along with 2 Least and 4 Elegant Terns. There were a few Black Turnstones and Black Oystercatchers, as well as a Spotted Sandpiper, on the breakwater.

https://ebird.org/view/checklist/S58527308

According to a resident, we missed the big Elegant Tern fly-out at Elsie Roemer by a couple of hours this morning. There were a few terns present when we were there at 11:45, but no where near the numbers in recent reports. The early bird gets the terns!
