Look up everyone

Aaron Maizlish
 

There are dozens and dozens of White-throated Swifts and a few Vaux’s Swift flying with the swallows around Berkeley Meadow. With this low cloud cover this morning in the middle of migration, the swifts are low. It might be our best chance to find a Black Swift in migration. I haven’t found one yet but please look up everybody if you’re on the eastshore.

Bald Eagle 680 near Stoneridge My first Bay Area sighting

Marcus
 

After 64 years,/10 months and 4 days I finally get to see a Bald Eagle in the Bay Area. I have seen them elsewhere from Lassen to Coco Beach, FL where they are as ubiquitous as the local night herons in Oakland hanging at KFC.. Had just gotten onto 680 from the Stoneridge on ramp (just after 6:25pm) and by the grove of Eucalyptus trees there were up to a dozen turkey vultures flying around and over the freeway which is pretty unusual, so I looked around and on my left over the canal I spotted a small bird harassing a larger one, thinking it might have been another vulture except it was moving around a lot, then I noticed the lighter head and then the white tail. YaYYYYY!! I wish I could have pulled over, was very tempted, but drove on. The smaller bird was really letting the Bald Eagle have it. My gf works in the area and thinks that she has seen it around as well. Finally!!!!

Cormorant Nests at Lake Merritt

Hilary Powers
 

The Double-crested Cormorants are back! This morning the nests on the bare trees all had cormorants sitting in them or beside them or arranging new sticks that others were bringing in.

Dunno why this year's breeding season had a hole in it....

Rose-breasted Grosbeak

Kay Loughman
 

For the *tenth* year since 1997, we've had a Rose-breasted Grosbeak visit our feeders!  Likely some of the sightings, as in consecutive years, were of the same bird - no way to know.  Mostly it's been males, but in at least two years there was also a female. Our yard has for decades been "grosbeak central", and we have several pairs of Black-headed Grosbeaks visiting our feeders again this year.  This morning's special guest was here only briefly before he was chased off by one of our highly territorial scrub-jays.    Fortunately, my camera was close by.  See a few photos <http://www.nhwildlife.net/album/New/slides/RBGR-8010c-72.html> here.

Re: Chabot Regional Park--Clyde Woolridge Entrance

Derek
 

Taking Judith's recommendation, I went up to try out this route and
the resulting attached trip report #41 added Northern Pygmy-Owl to
species seen there. Thanks Judith for suggesting this spot as I was
really surprised how interesting it was. Before this hike I made
fairly quick stops at Elsie Roemer (no shorebirds, no Brant) and
Arrowhead Marsh (2 White-faced Ibises, 3 Red-necked Phalaropes and a
single Western Wood-Pewee.

The Pygmy-Owl had a dead bird in it's grasp. I'd be interested to hear
opinions on what species folks think it might be.

I stumbled upon another spot in the East Bay hills with little eBird coverage. The Clyde Woolridge Staging Area of Anthony Chabot Regional Park had only 39 checklists over all years. Lydia Huang and I made it 40 this morning with our 5.8-mile hike.

We started at the staging area where Skyline Boulevard meets Grass Valley Road. From there we went down Jackson Grade to the Cascade Trail, which we took all the way to the northern arm of the lake. The habitat is diverse, typical of Chabot: grassland, oak woodland, and bay trees and dense vegetation filling the canyon through which Grass Valley Creek flows.

Our FOS species were SWAINSON'S THRUSH and CASSIN'S VIREO. Birdsong was continuous: Black-headed Grosbeak, Wilson's Warbler, Warbling Vireo. The bonus was a nice selection of wildflowers, including a number of globe lilies.

New family in town

While sitting upstairs after returning from Heather Farm Park in Walnut Creek, I heard the quiet sound of a baby bird in our patio.  We have been having the baby Juncos come to collect seeds, and I thought this was what I might be hearing. 

But I went downstairs anyway to look out the window.  We had three California Towhees, not the occasional two, and one was being fed.  The fledgling has very faint streaks on the breast, but looks mostly like an adult.  Not a first for us, but still exciting and fun to see.

Odd weather event--heads up for vagrant shorebirds!
Hi Everyone,

We're about to experience a fairly odd weather pattern with 2-3 significant
fronts stacked up very late in the season. It could be nothing, but it
bears keeping our thoughts and eyes open for trans-oceanic shorebirds that
could be affected on their way north. Species such as Bar-tailed Godwit and
Bristle-thighed Curlew come to mind. I wasn't living in California in 1998,
but I did manage to see the Kehoe Beach Bristle-thighed Curlew. The timing
here is similar. There was a lot of discussion then around the fallout of
BTCU from California north through Washington due to odd weather. A
subsequent paper is here:

http://www.meteo.psu.edu/~sbf1/papers/Mlodinow_Feldstein_Tweit_1999.pdf

In any case, it'll be an interesting week. Double-check those Whimbrel on
your local beaches!

Stellar's Jay near Pleasanton, plus some area populations seem lower than last year, and my Nutall's

Marcus
 

Saw a Stellar's on the road side and stopped for a bit. It seemed rather animated and moving around on the ground.  Location - Pleasanton - Sunol Road just south of Verona

For some of you this may be a rather common sighting but for me there are much fewer sightings than 40 years ago, similar to the California Quail that used to be more ubiquitous in the SF Bay Area when I was growing up. Maybe I have bad luck but I haven't seen a Stellar's Jay for years despite my hiking around.

On another note, my partner and I have noticed a marked decline in the number of swifts this season around the Thermo Fisher Campus, and a similar decline of Cliff Swallows a bit south where they nest. [ I can pinpoint the location if you like. Just send an email. ]    We were wondering if anyone else has seen similar declines in their local birds. The winter was a bit prolonged and perhaps had a negative effect despite the fact that as someone who grew up in the area, the winter seemed normal for 50 years ago.  On yet another note, the Thermo Fisher campus Canadian geese are now shepherding 9 goslings this year around the grounds, mostly the pond area.

My Laurel neighborhood Nutall's last month seemed to have abandoned their nest, perhaps for another location. We saw this happen a few years back when the male started on a nest across the street from my house, then abandoned it and started a new nest on the same tree. I do hope they come back next year.

Re: Phainopeplas at Lime Ridge, Walnut Creek

alanbade@...
 

I thought I'd add to the Lime Ridge sightings; we had three Phainopeplas while helping with Save Mt Diablo's Lime Ridge Mangini BioBlitz on May 4th, on SMD's Mangini property. They were fairly vocal. I'm just now getting our lists entered into iNat (SMD prefers iNat for their data over eBird). We also had a Nashville warbler, a Hermit, several Townsend's, Orange crowned, and Wilson's, along with many Ash-throated Flycatchers. Common Poorwill and a Western Screech owl during an evening effort. I attached the ebird checklists here if folks are interested. We were fortunate to have some very experienced birders helping, and it was a lot of fun.

I saw Phainopepla twice in the past few days, once at Don Castro Regional Park in Fairview and again in Palomares Hills (sitting on a light pole on Villareal).

I wonder if we are having an irruption as I have only rarely seen them around.

Castle Rock/Pine Canyon, this morning, 5/12/19

tracy_farrington
 

A morning walk in Castle Rock Regional Park (Walnut Creek), and further up into Pine Canyon,
produced some pleasant Springtime rewards. The setting, as is so often the case this time of year, was
positively bucolic: clear skies, mild temperatures, and just enough breeze to gently deliver the redolence
of our oak woodlands.
As I stepped from my car, I was greeted by a singing WILSON'S WARBLER. Shortly thereafter, at the outset
of my walk, I heard the first, of what would become several, ASH-THROATED FLYCATCHERS. West of the
swimming pool and adjacent to the basketball court, sits is a stand of Locust trees. As I expected, there
was a nesting pair of BULLOCK'S ORIOLES; what I did not expect, however, was to also find a nesting pair
of WESTERN KINGBIRDS. A kingbird nest, specifically in these trees, is a first for me.
WESTERN BLUEBIRDS were fairly abundant, and several of the bird boxes provided were occupied by them.
After leaving the recreation area, and ~200 ft. before getting to the first cattle gate, I heard quite a lot of
activity on the right (west side) of the trail. At about this point, there's an old wooden fence post that shares the
space with some short snags. To the left there's a good sized oak right next to the fence. In that one tree I found
two pair of Bullock's Orioles, each tending to a nest; another Western Kingbird nest; a pair of nesting
Western Bluebirds, and a couple of LARK SPARROWS, anxiously courting. The under-story was being defended
by a HOUSE WREN. In the nearby small, broken oak closest to the trail, a pair of MOURNING DOVES were
tending to their nestlings.
A bit further along, near the junction with Shell Ridge Loop trail, I first heard, then finally sighted, a LAZULI BUNTING.
I'm hoping for a successful nest, here. It's been at least three years since I've found any
sign of nest activity for this species, in this particular location.
The stretch of trail beyond, where the canyon narrows and becomes quite wooded, can be very attractive.
Several pair of AMERICAN ROBINS were found nesting, and a female BLACK-HEADED GROSBEAK was gathering
what appeared to be nesting material. In the distance a male was singing, non-stop. Moving on, another grosbeak was
heard, along with ORANGE-CROWNED WARBLERS (2), and a WARBLING VIREO.
Where the trail opens up, I climbed to the bench at the top of the berm, and found another nesting pair of House
Wrens. They were using the small wooden bird box in the oak just to the left of the bench. A BROWN CREEPER, was
singing, almost continuously, and by the looks of several dead branches supporting loose bark, I suspected a nest was nearby.
The face of the Castle Rocks to the north was backdrop for dozens of WHITE-THROATED SWIFTS, and VIOLET-GREEN SWALLOWS.
One pair of swallows was seen inspecting a couple of cavities in the large oak at the foot of the berm.
At times during my walk, I could hear the collective "laughter" of WILD TURKEYS serving as an occasional chorus, of sorts.
For more than twenty years I've had the good fortune, and the privilege, to live but five minutes from this wonderful and
accessible habitat.

Good Spring, and happy birding.

Del Puerto Canyon / San Antonio Valley / Mines (PAAS trip report)

Matthew Dodder
 

I led the second half of my Palo Alto Adult School birding class through Del Puerto Canyon, San Antonio Valley, and Mines Roads yesterday. Conditions were sunny and mild with increasing wind in the afternoon. Again we were unable to locate Blue Grosbeak or Costa’s Hummingbird at our usual spots, but we had many highlights nevertheless.

STANISLAUS:
Grasshopper Sparrow (1, on hillside just before cattle grate in grassland section)
Cassin’s Kingbird (3-4, on power towers near only surviving orchard in grassland section)
Rufous-crowned Sparrow (hard to miss in cottonwood grove and Graffiti Rock areas)
Lark Sparrow (several, in cottonwood grove)
Rock Wren (several, various rocky areas along road)
White-throated Swift (several nesting at Graffiti Rock)
Phainopepla (hard to miss in oak savannah areas)
Bell’s Sparrow (1, chamise across from playground on hillside at Frank Raines. During rare, but short-lived silence of ATVs)
Lawrence’s Goldfinch (2 at Creek Crossing, 2 at Frank Raines campground)
Canyon Wren (2, from overlook before Frank Rains picnic area, and in quarry just before Adobe Springs)

(Incidentally, the Odonata at Adobe Springs were wonderful. We had American Rubyspot, Flame Skimmer and Grappletail, and Painted Ladies were also abundant and seen throughout the day)

SANTA CLARA:
Tricolored Blackbird (200-300, at traditional pond near Junction)
Western Tanager (1 at Tricolored colony)
Lewis’s Woodpecker (4, in two areas along San Antonio Valley, south of Junction
Lawrence’s Goldfinch (1-2 south of large shallow pond on San Antonio Valley)

ALAMEDA:
Northern Pygmy-Owl (heard and seen in pine-oak woodland habitat near MP 18)
Golden Eagle (2 on Mines Road near MP 5)

(We also had a close encounter with a 3.5 foot California King Snake (around MP 5). A beautiful individual was sunning in the middle of the road. We pulled off and made sure it moved safely away from the traffic.

Green Heron in Glen Echo Creek, Oakland, 5/10/19

Kate Hoffman
 

I've been walking past the mouth of Glen Echo Creek for 5 years on the way to/from work, and I often see snowy egrets or black-crowned night-herons fishing in it. This is the stretch next to the Veterans Building where the creek is channeled (near the busy Harrison/Grand intersection) just before the creek empties into Lake Merritt. This week I spotted a green heron in the open--two days ago at the mouth of the creek and this morning fishing in the creek itself. The closest I've ever seen a green heron to this location is the islands near the Rotary Nature Center--not far as the heron flies, but this stretch of creek is extremely urban (there are homeless tents adjacent to it). Kind of amazing for such a normally cautious species.

White-crowned Sparrow coastal race in my parking lot

Patricia Bacchetti
 

HI all,


I work in El Sobrante, about 2.5 miles from the bay as the crow flies. Earlier this week, I heard a White-crowned Sparrow singing in the parking lot and thought that it was a late migrant. I went out to find the bird in a butterfly bush in the parking lot and was able to approach close enough to record the song-it was the nuttalli subspecies that's a resident and breeds along the bayfront. The song matched several that are archived on Zeno-canto https://www.xeno-canto.org/. https://www.xeno-canto.org/

This is a species that is known for breeding right along the bay, though the Contra Costa Breeding Bird Atlas discusses historical records that had it breeding as far east as Lafayette. They seem to like the fog belt and scrubby habitat, and several breeding pairs were discovered in suburban neighborhoods and the edges of golf courses. I've worked here for 28 years and have never seen a White-crown in the summer months, and because I'm interested in these subspecies I was particularly pleased.


Appearance-wise, nuttalli has a yellow bill, brown body, tan and black scapular stripes, and a short primary projection (it doesn't migrate). It looks alot like the wintering White-crowns that we see, the pugentensis subspecies, that breeds along the NW coast of Canada and Alaska. They can be differentiated by their song.


Another exciting recent discovery is Old San Pablo trail along the SE edge of San Pablo Dam reservoir. A turnout lane on San Pablo Dam Road, just past Bear Valley Road, takes you through 1.6 wooded miles to the boat launch area. The road is free-I thought that you had to pay at either end. It parallels the EBMUD Orinda Connector Trail, but if you don't have time to hike it you can drive through wonderful habitat. Even at 3:00 PM, I recorded 37 species-the highlight was a calling WESTERN WOOD PEWEE.


Good birding,


Pat Bacchetti
