Re: Possible Cassiar Junco (J.h. Henshawi), Martinez, Contra Costa Co.

Alvaro Jaramillo



  I think that may be a straight Slate-colored, the Cassiar birds I have seen in Alberta have a lot more brown on the tertial edges etc. Young males and female Slate-colored have brown washed backs too, this could be a young male or dark female?


Great find!!

Oyster Bay 12/5 - Kumlien's Iceland Gull (or perhaps very pale Thayer's?)

Noah Arthur

This afternoon John Cant and I gulled Oyster Bay Shoreline in San Leandro, mostly focusing on the large congregation of gulls bathing and loafing on the slough on the north side of the park (I call the place Tufted Duck Slough because of the distinguished visitor it harbored last winter). Best bird was a gray-winged Thayer's-type that we identified as a third-cycle KUMLIEN'S ICELAND GULL. The bird never flew, but when I looked back at my photos later, I realized I'd photographed this same bird on Tuesday, including a blurry but telling flight shot! The dark marks extend only to P6 at best. The head and bill are a little bulky (although, of course, the apparent shape changed from moment to moment depending on posture), but I don't think those wingtips are within the range of variation of known Thayer's Gulls. I'm open to suggestions, though!
Another interesting bird was an adult Western or Western-type gull with yellow legs. Will let you know if this bird turns out to be a Yellow-footed Gull, but for now I'm not calling it anything other than a Western until further notice.

Hi All, I went to Midway Rd around 4pm Thursday Dec 5th, was able to see the ROUGH-LEGGED HAWK perched on the second tower west of the barn.

Also saw FERRUGINOUS HAWK flying around being chased by Ravens.



Clay-Colored Sparrow at Miller Knox

Jeff Acuff

Today a clay-colored sparrow was foraging with white-crowns in the bare grassy area leading to the pier.  There was also a Say's phoebe and an American pipit.

The pond had 13 red-breasted mergansers and one common.

Re: Painted Redstart continues

katie bertsche

Well, it made it through last night, since I can hear it call from (presumably) near the oak tree today, at about 11:45.   Met some folks looking for it this morning, not sure if they actually found it or not.

Tropical Kingbird Richmond Bay Trail continues

Susan Greef


Today, Marilyn K. and I refound the Tropical Kingbird I reported yesterday.  We found it about 12:30 pm, approx 50 yards from where originally seen.  Loc:  About 50 yards up on the Marina Bay paved trail from where it intersects with the Richmond Bay trail, a paved spur trail comes in.  At that intersection there is a small coniferous tree and it was in there with a mixed flock of robins, Cedar Waxwings and others.  We only saw it long enough for confirmation, then it disappeared and we did not see it again.  Good luck!

Greater Roadrunner - Patterson Pass Rd


A chilly morning for it today, but I searched from 10-11:30 and still failed to produce a Rough-Legged Hawk on or near Midway Rd at Patterson Pass Rd.  I saw plenty of Red-Tailed Hawks, kestrels, shrikes, and a Golden Eagle.  On my way west on Patterson Pass Rd., at MM 6.04 as has previously been reported, I found my first Greater Roadrunner ever for Alameda County (finally).  The bird was running along the embankment on the south side of the road and perched briefly in the smaller of two oaks at the mile marker sign.  A gorgeous, big, brightly-plumaged bird.

Oyster Bay 12/4 gulls and geese

Noah Arthur

I spent most of my time at Oyster Bay this afternoon looking through the thousands of big gulls coming and going from the slough on the north side, but there were a few other (more interesting) sightings. Two GREATER WHITE-FRONTED GEESE flew over while I was there, and a good flock of BONAPARTE'S GULLS were on the slough. In the gull flock were at least one possible Kumlien's Iceland Gull and one possible Slaty-backed; not sure about these ones but will keep you posted if I ever figure them out.
This is a very good place to look for rare gulls... easily as good as the Pacific Commons pond used to be. Please photograph any gulls that look odd if you visit! Strange things show up in this gull flock...

Ferruginous Hawks at Dublin Open Space


Today I saw two (possibly three) Ferruginous Hawks at Dublin Open Space.  (At least one adult and one very scrawny looking immature bird.) 

Only a few red tails hawks were seen.  Other raptors:  Golden Eagles, Kestrels, Kites, and vultures.

Almost NO ground squirrels.  I don't know what these birds are finding to eat.

Also one coyote.

Patterson Pass

Clark, Bill <clark88@...>

At noon today, the Rough-Legged Hawk continued at the south end of Midway Rd, on the west-side of the road, flying between the two electrical towers.


On the way there, after years of trying, I finally spotted the Greater Roadrunner at MP 6.2 on Patterson Pass Rd.  It was on the south side of the road, across the arroyo and walking along the cattle trails there.


Also along the road: Mountain Bluebird, Say’s Phoebe, Loggerhead Shrike, Prairie Falcon and Tri-Colored Blackbird.

At 9:20 this morning there was an adult SNOW GOOSE with about 140 Moffitt's Canada geese, and 11 members of the CACKLING GOOSE species; I think all were Aleutian but am asking an expert to look at a photo of a small bird with apparently small bill.

Re: ROUGH-LEGGED HAWK continues on Midway Rd. (12/2)

Jerry Ting

Mid-day today (12/2) the Rough-legged Hawk continued at the south end of Midway Rd in Tracy.  Perched on the tower most of the time, the RLHA occasionally flew down to the field but I didn't see it caught anything during my 1 hour observation.  Here are a couple of in-flight shots with terrible light:


Also presented in the area include:

Golden Eagle (1)

Red-tailed Hawk (3)

American Kestrel (1)

Turkey Vulture (several)


Happy Birding,

On our way back from Thanksgiving holiday in Southern California, Juli and i stopped at the southern end of Midway Rd off of Patterson Pass Rd and found the continuing ROUGH-LEGGED HAWK in exactly the spot that Bingham Gibbs described. It was perched on one of the two power poles directly behind the barn on the west side of the house. While we were getting scope views from the road, we were lucky to have the very friendly property owner drive up. When we told him about the rare hawk, he invited us to hop the fence into his pasture for a closer look. (It should go without saying that one shouldn't enter unless invited.) Also present at this spot were a Golden Eagle, several Red-tails, and an adult Cooper's Hawk chasing pigeons out of the barn.

Clay-colored & White-throated Sparrow at Miller/Knox

katherine francone

I try to get out and take a walk around the lagoon at least 3 or 4 times a week.  Things appeared very quiet
today(4:30pm) until I hit the parking lot that is before the Ferry Point parking lot. At the entrance area to the lot
there was a flock of 100+ sparrows feeding on the grass and in the lot itself.  At one point they moved into
a picnic area entitled Sea Gull and were feeding on the ground.  In this group there was a Clay-colored sparrow,
a White-throated sparrow(white-striped) and a Slate-colored Junco.  I took a few bad photos of the birds and will try and send later.  Good Birding

Contra Costa county 12/1/13

Logan Kahle

Hi all,
Today Denise White and I birded various spots in Contra Costa county, primarily in the far western side and the far eastern side.

We started at West County Wastewater Treatment Plant, which was fairly inactive with the exception of a calling Orange-crowned Warbler in the low shrubs lining the plant.

We then proceeded on to Miller/Knox in hopes of adding Pacific Loon to Denise's Contra Costa list. Unfortunately, we could not refind the previously-reported bird, though there was a nice Red-throated Loon in its place. In the distance, we saw a flock of Red-breasted Mergansers, a late Heermann's Gull, and a handful of Pelagic Cormorants. On the pond, one male Eurasian Wigeon was among the Americans. A few shorebirds were scattered along the edge of the pond, including decent numbers of Black-bellied Plovers. In the nearby trees, we heard Red-breasted Nuthatch, House Wren, and Bewick's Wren. At Sandpiper Spit, we found a Townsend's Warbler and scoped a massive flock of Dunlin that contained some Sanderling among it.

We continued onto the Canal Blvd observation platform, where we got good views of Brook's Island. On the island, we found a feeding Peregrine Falcon and a feeding Osprey. Off to the south, we found another Red-throated Loon. There were several distant loons past the breakwater, though they were too far to identify to species. From Vincent Park we found and photographed the male Black Scoter, and found a Willet and a few Black Turnstones on the nearby riprap.

Mallard Reservoir was active as usual, with good numbers of shorebirds including a Semipalmated Plover, a single male Eurasian Wigeon, 350 Ring-necked Ducks, and four Horned Grebes. Unfortunately, we could not locate any Redheads.

We then drove along Marsh Creek rd where we found a single Prairie Falcon as well as a few Loggerhead Shrikes. Four Common Mergansers were on Marsh Creek Reservior. At the Walnut Trail at Los Vaqueros Reservior, we found four Lewis's Woodpeckers as well as a flock of Long-billed Curlews (in the field) and a White-breasted Nuthatch.

At the Byron WTP we found a Ferruginous Hawk and a Wilson's Snipe. Our trip to the Byron Airport Preserve was highlighted by two Golden Eagles, two Burrowing Owls, and a flyover Horned Lark.

Clifton Court Forebay was very inactive, as almost all of the ducks (there were thousands of scaup present, most of which appeared to be lessers) were too far to sort through. However, there was a second-cycle Western Gull on the edge of the reservoir, which I assume must be uncommon at this site.

At the Holland Tract, we found another Ferruginous Hawk, a distant flock of Sandhill Cranes, many Greater White-fronted Geese and a Ross's Goose.

At the Big Break observation platform, we found a group of Common Goldeneyes with a single female Barrow's Goldeneye mixed in. Both Sora and Virginia Rail called from the reeds. A massive flock of well over 100 Yellow-headed Blackbirds flew in overhead, likely roosting nearby. Four Great-tailed Grackles flew west.

At Iron House Sanitary District, the shallow pond was completely dead. There were only two Killdeer on the mudflats. I have never seen it so empty. The deep pond, however, was happening, with hundreds of Boneparte's Gulls, dozens of Common Goldeneye, and hundreds of Bufflehead present among other common duck species. At dusk, three female Hooded Mergansers flew out of the pond. Over the marsh, we saw many Northern Harriers and White-tailed Kites as well as some Great Horned Owls. Large numbers of Blackbirds came in to roost on the telephone wires, and among them was at least one Tricolored.

Overall, we saw 137 species for the day, which is not bad given that we weren't really trying to get a high total and did not enter high country at all (and consequently missed birds like Steller's Jay and Fox Sparrow along with dozens of other common upper-elevation residents and many other assorted ducks, chaparral birds and shorebirds.)

Good birding,
Logan Kahle
