Barrow's Goldeneye - Antioch City Reservoir - 121/31

Paul Schorr

This afternoon, on return home from an errand, I made a brief stop at the Antioch City Reservoir. The gusting winds created rough water and heavy white caps, so it was challenging trying to spot the birds that were diving and only on the surface briefly. However, among the mixed flock of Buffleheads and goldeneyes, I did spot a single male Barrow’s Goldeneye. However, there may have been additional Barrow’s among the numerous Common Goldeneyes.

In addition, among the 50+ Canada Geese on the adjacent Lone Tree Golf Course, there were at least three Aleutian Cackling Geese.

Happy New Year and Happy Birding in 2019.

Heather Farm 12-31

David Kent

My last wander around Heather Farm for 2018 started cold and windy. Ran into Hugh Harvey at the railing and Fred Safier with whom I walked back to the canal. Did I mention that it was windy? ...and chilly? Little was stirring (at first) not even a mouse! Except for the Canada Geese (and 1 Cackling Goose), at least 30 Double-crested Cormorants, and the usual assortment of other waterfowl.

However, after about an hour the wind started dying down and the birdies came out!

Of note for HF were a Red-tailed Hawk over the canal and a Turkey Vulture soaring over the natural lake. The (probably) resident Common Gallinule came out of the reeds, showing a lot of red on its shield. The continuing Tropical Kingbird was hawking insects over the cement pond. Six Black-crowned Night Herons were dozing on and about the island. A Belted Kingfisher was heard. A lone Red-winged Blackbird showed up on the west side. We heard a few spring songs, as opposed to the practice notes we have been hearing, and the American Goldfinches are showing a bit more yellow.

Happy New Year everyone!

Summer Tanager continues today in Claremont Canyon Regional Preserve

David Quady and Nancy Boas


About 12:45 pm today, the adult male Summer Tanager appeared in the oak tree described yesterday by Bob Toleno and Juli Chamberlin. It is located at
37.8639434, -122.2432396 on the Stonewall - Panoramic Trail, in Oakland. A half-hour or so later, as I walked down the trail toward Belrose Ave in Berkeley to fetch my car, I joined a few birders who had relocated the tanager in eucalyptus trees a couple hundred yards down from where it first appeared.

Good luck to others who seek the bird.

And happy New Year.

Summer Tanager continues at Claremont Canyon

Bob Toleno

Juli Chamberlin and i got fantastic views of the continuing SUMMER TANAGER
in Claremont Canyon earlier this afternoon. We found it uphill from where
others have been reporting the bird, feeding for quite a while at the sap
wells drilled by a sapsucker in an oak tree. The exact coordinates where we
found the tanager are here:

37.8639434, -122.2432396

We ran into David Tomb at the bottom of the hill, gave him those
coordinates, and he was able to find the bird at the exact same oak tree
nearly an hour after us, so this may be a fairly reliable spot for others
to look. It was our third attempt to see this bird, so i guess third time's
the charm! eBird list with digibin photo is here:

Good birding,

Heather Farm in Walnut Creek


Despite the cold, some interesting observations have been made in Heather Farm Park the last week or so. We have fairly regularly seen a Fox Sparrow on the west side of the big pond, coming out to the seeds I toss for the other sparrows and the occasional squirrel.

The numbers of ducks varies day-to-day and even throughout the day. Today we had 65 Ring-necked Ducks and I counted 25 Buffleheads. Other days they are smaller numbers. By the afternoon, the numbers are generally lower.

We have had a very large number of Double-crested Cormorants in the mornings. Today Fred tallied 35 on his eBird list, which can be seen here:

Fred usually has a few American Goldfinches which I manage to miss, but today he pointed out a small flock on the northeast side of the big pond. Then, along the trail next to the dog park as we walked toward the Contra Costa Canal, we had a small flock of Cedar Waxwings.

Christmas Day I sang Happy Birthday to my bike as I entered the park. It was 60 years ago when it arrived in the garage of our Cincinnati apartment. It must have been one of the best presents ever, as I still ride it almost daily.

It was also in Cincinnati that we had a Cedar Waxwing crash the dining room window. We picked it up outside, brought it in, and my mom showed us a painting of it in a large National Geographic book from the 1930s. Thanks, Mom.

McNabney Marsh, Mallard Reservoir, Meeker Slough


Hi All,

Today (12/24) I visited Waterbird Regional Preserve and McNabney Marsh from around 11 to 12. The undoubted highlight of the visit were 12 (yes, 12) Blue-winged Teal. This is, to my knowledge, the second highest count in the county ever, the highest being Steve Glover's count of 13 in the year 2000, the one year Blue-winged Teal bred in the county. I find that scoping the preserve from the South viewing platform (accessed off Arthur Rd) allows for a better chance at spotting these birds. Most of the Blue-winged Teal were male. Mute Swan numbers were low at 2 birds and there were several American White-Pelicans. There were also 3 Lesser and over 25 Greater Yellowlegs in the preserve and an astounding and painstakingly counted 83 Snowy Egrets. There were 6 Hooded Mergansers and the familiar Peregrine Falcon was soaring over the refineries.

Yesterday, I headed out to the Meeker Slough area to look for the Nelson's Sparrow at high tide. Joining me in the search were John Luther, Jim Lomax, Melanie King and others. The bird was elusive yet present, best seen at high tide (around 11:30am). For more details and GPS coordinates please refer to my eBird checklist: Other notable sightings included a flyby Common Loon on the bay, rafts of several hundred scaup, a pelagic cormorant swimming around happily in the marsh, and distant scope views of the herring run on Brook's Jetty. Even from the great distance I was at, it appears that numbers of birds have increased from several days ago and several thousand cormorant lined the jetty and many gulls swum in the water. I encourage everyone that can to head over to Miller/Knox shoreline or Canal Blvd. viewing platform and check out the herring run for possible Long-tailed duck, Harlequin duck, Slaty-backed gull, Pacific Loon and others.

Two days ago, I headed over to Mallard Reservoir at around 11, an often unjustly underbirded reservoir in Martinez. There was nothing rare around, but bird numbers were high. Mallard reservoir currently has both mudflats, shallow water, and deep water. The king tide pushed in good numbers of peeps to forage. Around 85 Least Sandpipers, 6 Westerns, 16 Dunlin and about 30 dowitchers foraged together. A snow goose (quite rare outside of East county) flew around over the reservoir with two Canada Geese. 15 Mute Swans graced the reservoir, disappointingly along with 13 Forster's Terns. Other notable sightings included several Canvasback rafts, one Bonaparte's Gull, one possible and distant female Eurasian Wigeon and zero scaup. There were also around 600 gulls in the reservoir, most close enough to ID with binoculars. The lack of Glaucous-winged (2) and Iceland (0) gulls was disappointing, but there were easily over a hundred Herring Gulls. At dusk these numbers could greatly increase providing for good gulling. If anyone wishes to check it out, bring a scope, as there are only a few vantage points along Bates Ave. and the birds can be far away.

Good birding,
Ethan Monk

Rough-legged Hawk


Today at approx. 9:15AM I found a Rough-legged Hawk in eastern Alameda
County. I stopped at a pullout on N. Midway Rd where the old railroad line
crossed the road. From here you can see much of the valley to the west and
all the high power towers. Scanning with my scope I spotted the RLHA perched
about hallway up a tower to the south-west of my position. It's been a few
years since a RLHA has been reported but this is the general location were
they have been seen in past years. I cam back about an hour later and it was
still in the same location.

Ebird report here with a few very distant pics.

Slate-colored Fox in the yard

Noah Arthur

This afternoon a very distinctive Fox Sparrow that appears to be a ‘SLATE-COLORED’ FOX SPARROW showed up at my Oakland Hills backyard feeding station. Soft, relatively pale medium gray face and back, contrasting with reddish wings — very unlike the dark, muddy, uniform upperparts of ‘Sooty’ Foxes (which have also been frequenting the yard). 
Unfortunately this was just before I left for the airport to fly down here to Ventura for Christmas. I think I’ll be back home by the end of the week though; I’m hoping the bird sticks. If anybody wants to come see the bird if it’s still around by then, give me a call or email!

Arrowhead Marsh Sunday Dec 23

kathy jarrett

Starting at the EBRPD Tidewater staging area we bicycled along the Bay Trail to Arrowhead Marsh, taking advantage of the high tide to see a Sora, a couple of Ridgway's Rails and a large number of Great Blue Herons hoping to catch a meal. We were surprised to see no Surf Scoters in the channel when we began but there were large numbers on the return trip. There were large rafts of Ruddy Ducks and Scaups. Thanks to Ken who let us use his scope to see the birds in Pond #3 at the southeast corner of the park; there we saw Wilson's Snipe, Green-winged and Blue-winged Teals, American Wigeons and Black-necked Stilts and more.

eastern contra costa, Saturday, 12-22

Bruce Mast

Good evening EBBers,
Spent the day with Holly Bern poking around east CoCo in search of some
recent rarities. Started the morning at Clifton Court Forebay with gulls
and ducks. Driving into the forebay parking lot and to the end of the
peninsula where the fishermen congregate, the gulls were mostly roosting on
an island to the south. Lots of Herring and California Gulls, a noticeable
number of Iceland (Thayer's) Gulls, and a few Glaucous-Winged Gulls.
Nothing rare. The fishermen were using a novel casting technique, which
consisted of using a drone to tow their bait offshore and then drop it.
Beats casting by hand, I suppose. We also scanned for ducks, with thousands
to choose from but, again, nothing rare.

We then headed north to Orwood Road. We birded its length to the marina
(having texted Will in advance that we would be coming, to which he replied
"ok, have fun". See Hugh Harvey's note from 12/20.). Logged a couple
Loggerhead Shrike and 4 Lark Sparrows with Zonotrichias at the marina but
nothing rare.

We finished up at Holland Tract, where the highlight of the day was to
refind the continuing WHITE-WINGED DOVE, associating with a large flock of
Eurasian-Collared Doves. I believe the technical term is "scads". Also
noteworthy was 1 scad of Mourning Doves.

Bird on,

Western Contra Costa county 12/20 returning WINTER WREN, Lark Sparrow

Logan Kahle

Hi all,

Yesterday morning I got out to Richmond with Jonah Benningfield, joined for part of the time by Ethan Monk, Lucas Stephenson, and Mark Stephenson. I primarily wanted to bird Point San Pablo, but with overcast to foggy conditions I opted to check some other spots beforehand, letting the fog clear at the Point before we made our way out there.

We started at Wildcat Creek, walking the section of riparian between the railroad tracks to the marsh. It seems that some birds follow the riparian downslope into the lowlands, as there are certain species uncommon in parts of Richmond that are more fully represented here. Some highlights along the trail included:
Hairy Woodpecker-1
American Pipit-1
Lincoln's Sparrow-2
Townsend's Warbler-2
Orange-crowned Warbler-2
Full eBird checklists here:,

We continued to Point San Pablo, where we spent the rest of the morning. With low overcast (remnants of the morning's marine layer) and mid-low temperature it was less than ideal conditions in my experience for this spot. Optimal is normally sunny, perhaps better when it is foggy to the west of the point. In any case, we covered the ship hull overlook, the county park, the oaks, and the marina area. Overall activity was moderate, with a few distinct highlights. Highlights included:
Horned Grebe-40 was slightly high for this sight
Eared Grebe-2 were very good birds for the point. This species has a somewhat patchy distribution in Richmond, and it is possible that the waters off San Pablo are not as shallow or calm as they prefers
Black Oystercatcher-1
Black Turnstone-1 at the Marina was a surprisingly low count for the typically very large high tide roost
Pelagic Cormorant-1
Merlin-1 very pale male
Peregrine Falcon-1
PACIFIC WREN-1 was my first for the point, and overall a very rare bird in richmond. This bird was in the first gully in the oaks, just past the first hairpin turn. Birders chaing the Winter Wren should be wary that there is a Pacific Wren in the oaks as well
WINTER WREN-1 returning bird from last winter calling at the same place as last year (37.9630959, -122.4224836) in the poison oak-filled canyon just passed the second hairpin turn on the north side of the point. The bird was about halfway from the hairpin turn to where the road next turns at the top of the gully. It was quite vocal, calling spontaneously every 5 or so minutes. I have found this bird is most vocal in the early morning, but on an overcast day like yesterday it was loudly calling at 10am.
LARK SPARROW-1 high-flying, calling northbound flyover at the top of the hill just before the oaks was a very rare bird in Richmond. It seemed like the bird started to drop down towards the tip of the point, possibly angling toward the gravelly patch at the very tip of the point. This bird appeared to me, given time of day and year, to be a (late) active migrant. Fall isn't quite over...

A full eBird checklist can be found here:

Was great to get back to some of the more interesting spots around Richmond for a drizzly morning, with 90 species observed.

Good birding,

Eastern Contra Costa county 12/15/18--106,000 Coots!

Logan Kahle

Hi all,

On 12/15, I birded at some of my preferred East county spots with Jonah Benningfield, starting early on Bethel Island. The majority of the day was spent checking this island, including Piper Slough, the Harbor road (flooded) fields, the neighborhoods on the south shore of the island, Willowest Marina and the Franks Tract Overlook. We started at Piper at dawn with hopes of high waterfowl numbers, and found expected tallies of geese but very few ducks. The real highlight of the island was the absolutely monumental number of Coots on Frank's Tract. It was impossible to get a truly accurate count, but counting by 1000s I estimated 106,000 individuals on the tract. This is far, far more than I have ever seen there, with a typical winter flock numbering in the 10-20,000 range. The flock extended across the entire tract, approximately 2.5 miles in length. It seems likely this is one of the largest coot concentrations in California at this time. I strongly encourage any experienced counter to go to this site and try to estimate coot numbers at this time. Anyway, highlights on the island included:

American Coot-106000 was an absolutely incredible count
Lesser Yellowlegs-3 in the fields was about the expected number for wintering birds
Western Gull-1
Virginia Rail-3
RED-BREASTED SAPSUCKER-1 was a very rare bird in the East Contra Costa county islands
PACIFIC WREN-1 at Piper Slough was my first for east county

Full eBird checklists here:,

We continued onto Orwood Road, with the primary intention of finding the NORTHERN SHRIKE originally located here by Dan Kopp and Jose Martinez. We walked around the region and Jonah eventually spotted the shrike on a pole on the north side of the road, where it perched for about a minute. It then flew east, still on the north side of the road, and landed on a wire. We lost it shortly after this point while trying to relocate it.

Full eBird checklist here:

Rain was picking up, but I decided to head to Bradford Island to see what was wintering on the island. We found a few interesting birds around the island:
California Quail-1 female was the first I have seen or heard reported on the island. Whether this represents a small, isolated population or moving birds from adjacent islands is unknown
Mourning Dove-130 was a nice flight at the end of the day
Yellow-headed Blackbird-164 in huge blackbird flock on South End of island.
Red-winged Blackbird-15,500 was an estimate of a massive flock on the south end of the island

Full eBird checklist can be found here:

Nice to see so many birds in the delta portion of Contra Costa.

Good birding,


Re: Cruiser Haven Orwood Road

Noah Arthur

This is a situation where I would suggest that birders not visit the area at all. For the landowner, birder visits are an inconvenience at best (unsolicited texts, having to check license plates, etc.), even if the call-ahead rule is observed. This situation could easily end badly for the local birds, if the landowner decides to get rid of bird habitat on his property in order to keep away rare birds and therefore deter birders from visiting.

While visiting the marina yesterday during the MDAS East Contra Costa Christmas Count, eight birders were busy trying to find the recently reported Northern Shrike. We were approached by a man in a pick-up truck with whom we had a very satisfactory conversation.

But here is the deal--Cruiser Haven has recently suffered some vandalism in the form of arson. Birders are no longer totally appreciated on a drop-in basis. Please send a preferred text to Will at 925-752-1697 at least one day prior to a visit. Will would like to have names and car license plate in your text.

Will and some of the others with whom we spoke were very friendly and inquisitive about our finding of "Shrek." We were allowed to stick around until sunset, but they made it clear that things would be different in the future. Will also said that at least 22 feet of clearance must be left on the road by anyone parking at the marina. They occasionally have farm equipment moving along the levee.

We did not find the Shrek yesterday, nor did we find the Northern Shrike.

At the countdown dinner, we tallied over 150 species for the day.
