Thanks to Judi Sierra and Pat Mahoney for perfect
descriptions of where

to locate the bird. This afternoon Dal and I got excellent
views and

photos of the bird beginning within minutes of our arrival
at 1:30 and

continuing until we eventually decided to take a walk. I
was intrigued

with its relationship to this very old non-native
cotoneaster which was

indeed riddled with sap wells suggesting it has been used by

of sapsuckers as well as fruit eaters for the berries.

please, I beg you, don't play recordings for Mitchell Canyon poorwills

Maureen Lahiff

...or anyone else in breeding season!

We all know it is the height of selfishness to stress out birds by playing recordings.

Especially in breeding season.

Especially in heavily-visited areas like Mitchell Canyon.

We're not researchers doing science or careful censusing,
we are, at best, lovers of birds and conservers of birds.

Mitchell Canyon Poorwill and Cassin's Kingbird Question


Made a trip to Mitchell Canyon recently and I am pleased to announce that Common Poorwills are currently calling vigorously. The best places to hear and see them were on Red Road, specifically here (37°54'24.6"N 121°57'15.0"W). A small note, playing a tape of the birds will set them off calling at a much greater frequency if you are not having much luck. Other birds of notice were 2 Hammond's Flycatchers, Lazuli Buntings galore, Gnatcatchers, several Nashville warblers, and an early Olive-sided flycatcher here (37°54'55.7"N 121°56'55.9"W). Good luck!

On another note, it's 2018, and the pair of Cassin's Kingbirds have been sighted on Tesla Rd. again. I was wondering if anyone knew how to find these birds as I was going to try and find them this year. If you have any info please email z.querula@.... Thanks!

Mitchell Canyon to Deer Flat, Mt Diablo Apr 24

Dave Weber

After reading Jim Chiropolos’s report yesterday I decided to hike the Mitchell Canyon Fire Road today, the goal being Deer Flat where Jim had a Dusky Flycatcher. The gate to Mitchell Canyon was already open at 7:15 am. At the Black Point connector trail I took the Globe Lily Trail (Jim’s suggestion and a good one). On it I saw a Hammond’s Flycatcher and a Nashville Warbler. Back on the main road not far up from White Canyon there was a Hermit Warbler high in an oak and a heard-only MacGillivray’s Warbler along the creek. A Canyon Wren could be heard on the rocky slopes of Eagle Peak. After 3.6 miles and 1500 ft I reached Deer Flat. I spent about 1.5 hrs in the area. There were no mass quantities of Hermit Warblers as Jim saw, in fact none. At least three more Hammond’s were around along with some Pacific-slope FCs for a good study. At 11 am I found  a Dusky Flycatcher, maybe the one Jim saw – slim empid, smaller rounder head, small bill, Hammond’s-like eyering but not as bulged front and back, relatively short primary projection compared to Hammond’s. Heading down, the Canyon Wren was singing more loudly. About 12:30 pm back down in the canyon a Nashville Warbler was with four other warbler species along the creek, all bathing and preening.


Dave Weber,


Mitchell Canyon Warbler Wave + Chat


Mitchell Canyon (Mt. Diablo) was jumping with migrants this morning - I had 47 individual warblers of 7 species all through the canyon, with an especially big group at the junction of the main canyon trail with the Blackpoint Trail.  Other migrants included Western Wood-Pewee, Hammond's Flycatcher, Swainson's Thrush, and Lazuli Bunting.  On the way out, there was a Yellow-breasted Chat singing by the creek (heard only) about 200 yards upstream from the trailhead.

Full checklist here:

Happy birding,

European Finch

Margaret Strubel

I was shocked to see a European Finch on the thistle feeder in my backyard in Albany - very healthy individual.  At first, it was shooing away the Lesser Goldfinches, but after the 3rd day there is cooperation at the feeder.  Has a pink band on its leg.  I only see one.  Any idea if this is an escapee and who to contact?  It's not afraid of me which leads me to believe it could be an escapee.  Thanks fellow birders!

Birding Mitchell Canyon/Mt. Diablo

Jim Chiropolos

I birded Mt. Diablo and Mitchell Canyon Saturday and Sunday. Areas birded included Mitchell Canyon, Deer Flat (over three miles from the Mitchell Canyon entrance station up 1,500 feet of steep trails), Pine Canyon and North Gate Road.  

Mitchell Canyon and  Deer Flat were the best birding with Deer Flat being the best birding with migrant flycatchers and warblers literally in every tree. I saw more warblers in 30 minutes at the non-prime birding time of noon compared to 2 hours birding the Globe Lily and White Canyon Trail hotspots beginning at 8:30 am of lower Mitchell Canyon. It was like birding in the east during a warbler fallout.

The ebird lists for the two areas are included below for comparison:

I was very fortunate to get some really great looks at the more uncommon birds 15 feet away or closer in one of those rare birding days where the species you hope to see are very cooperative. Highlights included a singing Bells Sparrow 10 feet off the White Canyon Trail (!!!), a MacGillivrays warbler singing in the shrub 3 feet away from the sign at the Black Point trail intersection to the White Canyon Trail (!), a singing Canyon Wren in the slog up to Deer Flat, at least 12 Hermit Warblers at Deer Flat (Hermit warblers are high elevation migrants - they are common high and rare low....) and a posing Dusky Flycatcher at Deer Flat. Pine Canyon and North Gate Road held orioles and kingbirds in comparison with Mitchell Canyon, but very few warblers.

No one saw any Calliope Hummingbirds that I knew of on Saturday, and hummingbird numbers were very low. 

I wonder how many rare birds pass by unnoticed high up on Diablo at an area like Deer Flat - my favorite area to bird on Diablo .

Good Birding,

Jim Chiropolos

FOS Olive Sided Flycatcher


4/22 in upper Strawberry Canyon Berkeley. I have 4-22-17 as last year's date too. A nice edition to Earth Day.

Claremont Canyon local interest, Saturday 4/21

Bruce Mast

Hey birders,
I spent 3 hours yesterday morning hiking and birding in Claremont Canyon, from the fire road trailhead at Stonewall Road (behind the Claremont Hotel) up to the end of Panoramic Way. I spent most of my time standing around watching the hummingbirds visiting the bee garden surrounding the last house on Panoramic Way. Best hummers were an adult male RUFOUS  and a couple female-type RUFOUS/ALLEN'S HUMMINGBIRDS. No other Selasphorous hummers were in evidence but it wasn't for lack of effort.

Other good birds in the Canyon included an Acorn Woodpecker, a distant calling Olive-side Flycatcher on the ridge, a couple singing California Thrashers, and my FOS Black-headed Grosbeak. Golden-crowned Sparrows are still hanging around.

Hoping your weekend was filled with sun and birds.

Bird on,

Bruce Mast

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


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

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

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.

Wildcat Canyon assortment

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).

Dusky Flycatcher


Heard early this morning 4/14 in Strawberry Canyon upper trail, Berkeley this morning. It gave a combined what Geoffrey Keller describes as brrrit whit but to my ears, pee whit, several times.

Yesterday my yard had a FOS Wilson's Warbler. I haven't seen the over wintering orange-crowned and townsend's warblers since mid-March and the Black-throated gray since 4/1.

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

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!

Spring migrants included:
Yellow Warbler
Wilson's Warbler
Orange-crowned Warbler
Western Tanager
Black-headed Grosbeak
Western-type flycatcher
House Wren
Blue-gray Gnatcatcher
