Black Diamond Mines 4/19

Mount Diablo Audubon Society had a field trip to Black Diamond Mines Reg Park today; 58 species were identified.  A couple more were seen by some on the way out after the trip was over.  An Ash-throated Flycatcher was heard and seen across the canyon from the upper picnic area.  Higher up the hill an Olive-sided Flycatcher was also seen.  While climbing the canyon above the Hazel Atlas Portal, we had Blue-gray Gnatcatcher, two Hermit Warblers, a Wilson's Warbler, and both Audubon's and Myrtle Warblers.  Higher up we heard and saw a wonderful Canyon Wren.  A number of swallows of various species flew overhead, but we never saw or heard White-throated Swifts.

We had lunch at the visitor center adjacent to the entry kiosk, where we had Phainopepla, American Kestrel and California Quail.  House Wrens sang in various places, Turkey Vultures, Red-tailed Hawks, Ravens and at least one Cooper's Hawk were overhead.

spring migrants--Western Tanager in Piedmont

Bruce Mast
 

Good morning birders,
I heard a Western Tanager this morning on my morning walk through Piedmont Park. I take that as a sign that we experienced a pulse of migrants last night. In past years, I've been lucky enough to catch some migrant pulses in the high country on Mount Diablo and above Lake Del Valle. I've observed large flocks of Tanagers and Hermit Warblers moving through the canopy in oak savannah habitat. Sitting here at my desk, I imagine the same thing is happening right now. Get out and bird if you can.

Black-throated Gray Warbler in Walnut Creek April 18

rosita94598
 

Henry Wadsworth Longfellow is on my mind today, but a Black-throated Gray Warbler was in my binoculars at Heather Farm Park this morning.  It was high in the eucalyptus tree next to the gravel boat ramp at the south end of the large, mostly natural pond.  One male Ring-necked Duck is still hanging out on the island.  Lots of swallows of 4 species flying around today too.


As Judi Sierra mentioned, she had two Nashville Warblers as she returned to the parking lot early from the Mount Diablo Audubon field trip in Pine Canyon yesterday.   We had a total of 54 species seen or heard by the group; not too bad for a day which saw starting temperatures in the 40s.  Other birds of note for that trip: 
Bullock's Oriole, Western Kingbird, Rufous-crowned Sparrow, House Wren, the three western Vireos, Brown Creeper, Black-headed Grosbeak.  Even a Wrentit allowed itself to be seen.

Just to add two Nashville warblers were seen by me as I returned alone to my car. They were on the creekside in 2 different spots well vegeated of the trail midway between the first meadow and the dam

A day which started with a temperature in the
40s became a wonderfully
beautiful day by the time we reached
the Castle Rocks. A number of
wildflowers were blooming, including
the Mt. Diablo Fairy Lanterns, but
of course we were rally paying
attention to the birds.  A total of 54
species were identified, the famous
Peregrine Falcons making themselves
hard to miss.  Other birds for which
we hoped were also seen or heard by
most of he 15 participants: Bullock's
Oriole, Western Kingbird,
Rufous-crowned Sparrow, House Wren, the
three western Vireos, Brown
Creeper, Black-headed Grosbeak.  Even
a Wrentit allowed itself to be seen.

Ruddy Turnstone, Ferry Point/Miller Knox, Richmond

Sheila Dickie
 

The previously reported Ruddy Turnstone was observed today, April 17, from 3-3:30 p.m. in the company of a small flock of about 10 Black Turnstones near Ferry Point (Miller Knox Regional Shoreline Park) Richmond. Location: Walking toward Ferry Point from Miller Knox on the west side of the park where the RR tracks are, the turnstones were observed foraging along the rocky shoreline just before you get to the abandoned building and near the chain link fence with three "Restricted Area" signs posted. If one of the turnstones had not moved, I might have missed them as they were so well camouflaged among the rocks. Tide seemed to be going out. I did not see any Surf Birds.

Two Caspian Terns put on a diving display, and looking out to the left from Ferry Point toward the breakwater there were three Red-throated Loons swimming near some snoozing large grebes.

Flycatcher and Sparrow, Pt Pinole, Richmond

Sheila Dickie
 

Yesterday, April 15, there was an Ash-throated Flycatcher in the small copse on the corner of the Sobrante and Cook's Point Trails (near the new Atlas parking lot) at Pt Pinole Regional Shoreline Park, Richmond, just before 2 p.m. It was still there when I was on my way out of the park at 4 p.m. In the same spot there were several hummingbirds floating about in the under-story; one Selasphorus and a couple of Anna's. They looked like either females or young birds.

Round about 3:45 p.m. there was a spectacular adult Lark Sparrow foraging along the grassy edge of the Cook's Point Trail near the restrooms in the Atlas parking lot (opposite the large meadow).

Couple of notables at Miller-Knox

Michael Carnall
 

This morning I sighted what looks like a golden winged warbler in the trees west of the pond at Miller-Knox park.  It is the second time I've seen it in the last week or so.  Definitely  had bright yellow crown and wing panels.  Hopefully others can confirm.

Also noted four Eurasian collared doves in the same area.

Hello all,

If you want a fix of seabirds this weekend, we are on for a Half Moon
Bay pelagic on Saturday. Weather is looking good right now, so we are ready
to go. Lots of possibilities, arriving shearwaters, breeding plumaged
alcids. Great chance for Laysan Albatross in with Black-footed Albatross.
Marbled and Ancient Murrelets are possible. Migrant phalaropes should be out
there, and migratory flocks of Bonaparte's Gulls, migrant Grey Whales and
more.

If you are interested, you can contact me or book directly here:

take care all, and we are so looking forward to this seabird season!

This afternoon we had a FOS Orange-crowned Warbler at our bird bath. I am sure that it would have stayed longer, but an American Robin scared it off.

Castle Rock Park/Diablo Foothills Regional Park, Walnut Creek

tracy_farrington
 

A fairly short (~1/2 mile) mid-morning walk along the main trail through the Castle Rock Recreation area, and then beyond the first closed cattle gate and into Diablo Foothills Regional Park, was quite birdy, producing a nice assortment of species. On the park boundary fence just west of the first picnic area I had a single CHIPPING SPARROW singing quite vigorously. In the same general area, the WESTERN BLUEBIRDS were abundant and nearly all of the nest boxes were occupied or being inspected. In the large Valley Oaks surrounding the pool area, a WILSON'S WARBLER was seen; two others heard. South, beyond the ball field, I saw the first of ten actively singing HOUSE WRENS that I would find. Just short of the closed cattle gate, I located one female LAWRENCE'S GOLDFINCH and a WESTERN KINGBIRD. Many YELLOW-RUMPED WARBLERS seemed to be just a few feathers short of alternate plumage. I did not see any Myrtles among them. Further south, from the old flood control dam to the first slope with the viewing bench, I had a single BLACK-THROATED GRAY WARBLER, three WARBLING VIREOS, several more Wilson's Warblers, one PACIFIC SLOPE FLYCATCHER, and a PEREGRINE FALCON roosting on the Castle Rocks. There were modest numbers of VIOLET-GREEN SWALLOWS, as well. In addition, I saw six actively singing BEWICK'S WRENS over the course of my walk. Things will only get better and more promising in the coming weeks. 


Good Spring birding,

A Black-headed Grosbeak (my FOS) was singing nicely near Jewel Lake (between the Nature Center and the Lake) in Tilden Park this morning.

Black-headed Grosbeaks - Lafayette - 4/9

Paul Schorr
 

Yesterday (4/9) we birded some of the trails from Lafayette Community Center. Black-headed Grosbeaks were clearly abundant and we estimated that we encountered at least six, both male and female. Their melodious songs were widespread.

In addition, we spotted a male Myrtle’s Warbler in stunning breeding plumage.

We had five woodpecker species including: Hairy, Downy, Nuttall’s and Acorn Woodpecker, along with Northern Flicker.

Lafayette Community Center is located at 500 St. Mary’s Road.

Good birding,

Pine Siskins Lingering

Elizabeth Leite <e.leite@...>
 

This morning , while observing for FeederWatch, I counted 6 Pine Siskins together at a feeder complex. Since this seemed late to me for siskins to still be in Central Contra Costa, I checked ten years of my FeederWatch records and only found one other year with a significant count during this last week of the program. I also checked eBird sightings for this time of year in my area going back ten years. I guess they are happy with the bounty here.

Additionally, yesterday morning a FOS Brown-headed Cowbird was singing in one of our oak trees around 8AM.

Happy Spring Birding.
