I forgot to mention previously was a WILSON'S PHALAROPE in a large pond east of the radio tower hills and west of a large warehouse now being built. It is best seen from the last bend in the road before the parking lot. I have other April records, most mid-late April bu a few in early April.

Kennedy Grove Regional Rec Area--Overlooked Park?

Judith Dunham
 

After my friend Pam Peck and I hiked Kennedy Grove in El Sobrante this morning, I was surprised to see that the park has only 45 checklists on eBird covering all years. Then I had to kick myself: this morning's hike was my first visit ever to the park.

All the human action was in the large picnic area, where families were setting up for Easter. We hit the trail at 8:30 and did a 3-mile loop through woodland and chaparral over less than 3 hours, and ended with 32 species. Among the sightings: OLIVE-SIDED FLYCATCHER, WARBLING VIERO, WILSON'S WARBLER, and BLACK-HEADED GROSBEAK. The highlight was a visible pair of CALIFORNIA THRASHERS on a hillside engaged in a duet. We encountered birdsong at every turn. The many wildflowers and butterflies were a bonus. The upper trails are narrow with good elevation gain.

We only ran into four other people on the trails. My eBird list describes our route: https://ebird.org/view/checklist/S55221297

Re: Kennedy Grove Regional Rec Area--Overlooked Park?

Logan Kahle
 

Thanks for bringing this place to light, Judith,

This park is severely under-covered, but in my just two visits in the past couple years has proved very lucrative.

The park has a large diversity of trees, with large flowering bluegum eucs, old live oaks, a smattering of willow riparian, and a few patches of chaparral. It has had several good birds in the past, most notably a wintering Tennessee Warbler back in the '80s. The place has awesome potential, mostly in migration but also winter, if anyone is looking for a Berkeley Hills patch....

Good birding,

Logan

4/22/19: Mitchell Canyon

Patricia Mahoney
 

4/22/19, Mitchell Canyon: 9:30 AM, a White-throated Sparrow was low in some shrubs south of Mitchell Canyon Trail (fire road), just past the first trail intersection after the gate. White-striped morph, scope view.

Up on Black Point Trail near the trail marker with the no-bikes symbol, 6 Vaux’s Swifts chattered as they flew north. An Allen’s Hummingbird chased an Ash-throated Flycatcher across the hilltop before returning to perch in an oak for excellent scope views! Blue-gray Gnatcatchers sang and moved about in the chamise. I got buzzed by a few hummingbirds who shall remain unidentified.

2 silent Swainson’s Thrushes were observed: one in the creek bed north of Mitchell Canyon Trail and another farther back on the trail, moving around in the oaks.

Today’s singing warblers: Yellow-rumped (including at least one Myrtle), Wilson’s and Orange-crowned.

Golden Eagle flying above Hercules

Susana dT
 

Seen yesterday, Sunday 21st at 12:45 PM. I think immature Golden Eagle. I was surprised to see it flying above downtown Hercules while chased by a Red-tailed hawk. Then it flew east, over our yard, possibly to Fernandez Ranch Park. Bad video good enough for ID here (I had to use slow motion due to too much camera shaking):

Hammond’s Flycatcher, Canyon, Pinehurst Road

Patricia Bacchetti
 

Taking advantage of the beautiful weather Sunday, I birded Pinehurst Road from Oakland to the EBMUD Valle Vista Staging Area. Just before Canyon, a Western Tanger was singing in front of a residence. I couldn’t get a visual on it, but it was close by. In a deep patch of redwoods just past Canyon School, I heard and saw a Hammond’s Flycatcher. It took a minute for my ear to recognize the call because I hadn’t heard one since last year, but there it was. It was fly catching from a redwood branch and it called continuously. At the same spot, 3 Wilson’s Warblers were flitting around together, Warbling Vireos were singing, and several Pacific Slope Flycatchers were calling. Valle Vista had 2 Blue-gray Gnatcatchers, initially seen on the northwestern, or Redwood Trail, going right from the entry gate. They were in the chaparral just before the Redwood Trail goes steeply uphill, and they were flying back and forth from the chaparral to the conifers on the opposite side of the trail. Later I found a pair in the oak trees and willows adjacent to the parking lot and Canyon Road. I’m presuming that they’re the same birds because they weren’t being seen at the original location. An Ash-throated Flycatcher was singing and visible in the parking area. There wasn’t an Easter Bunny in sight, though it was a good day for other migrants.

Pileated woodpecker in Montclair hills

Wendy Parfrey
 

I just heard the loud, resonant call of a pileated woodpecker at my house and was able to locate it near the top of a redwood tree on Heartwood. It just flew south toward Shepard Canyon so if you live nearby open your windows and listen a bit.

A new yard bird for me, although it's the third one I've seen in northern CA.

Enjoy, Wendy

White-throated Sparrow, Richmond

Sheila Dickie
 

A White-throated Sparrow has been seen in my back garden twice in the past week, previously seen a few weeks ago, and before that end of last year. The White-crowned and Golden-crowned Sparrows seem to have left the premises. Location Richmond, 600 Block of 29th Street.

Oakland Tanager

I was delighted to have a male and 2 female Western Tanagers land in my Oakland flats yard this afternoon for a brief time. Not to happy the other day to have a eurasian collared dove on the the ground in my yard last week. All the yard Golden-crowned sparrows seemed to have departed last week also.

Pleasant Hill Grayson Creek birding

Alan Bade
 

In today's Grayson Creek bird survey (a monthly project with Friends of Pleasant Hill Creeks), highlights were two Western Tanagers (one male and female) in the trees along the creek near the new PH Library site. Also two Hooded Orioles (both males), a Wrentit, and one of the Red-Shouldered hawk pair we observed mating last month. At the second site near the new Carmax store, highlights are two Red-Shouldered hawks are both back in the same nest they used last year in the sycamores along Chilpancingo Parkway, north of the new CarMax store. Cliff swallows are gathering mud from the banks of Grayson Creek and building nests under the small bridge that crosses the creek halfway between Golf Club Rd bridge and Chilpancingo bridge. You can get a good view of them gathering their mud.
We are now up to 72 species recorded during the 18 months of the survey along two stretches of Grayson Creek.
Good birding, Alan Bade

Nesting Ash-throated flycatchers and other birds

Jerry Britten
 

For the first time, ash-throated flycatchers are building a nest in one of
the boxes on my property. Also, at least two more are occupied by western
bluebirds, one is being used to raise white-breasted nuthatch chicks, and
oak titmouse have already fledged from another. No house wrens this year
which is puzzling as there have been as many as 3 pairs at once some
years. Hopefully, violet-green swallows will start nesting soon in one of
them, as they often do. Elsewhere on the property I know of red-shouldered
hawks, turkey vultures, black phoebes and scrub jays nesting. I'm sure
there are more I haven't found.

Mt. Diablo south gate to summit April 30

rosita94598
 

Today was the Mt. Diablo Audubon Society field trip up South Gate Road to the summit of Mt. Diablo.  While it was not the birdiest of trips, we had some really nice birds.  The hillside just outside the south kiosk was not particular productive, though we heard a Wrentit and a Lazuli Bunting was seen.  After driving to Rock City, our first bird was an Olive-sided Flycatcher practically in front of our parked cars.  It had large white flank patches, but it never sang.  In Rock City we also had Black-headed Grosbeaks, Ash-throated Flycatchers, Blue-gray Gnatcatchers and Western Tanagers.
The Junction Campground had Western Bluebirds and another Gnatcatcher.  Blue Oak and Pioneer each had California Thrashers.  Pioneer also had Spotted Towhee, Wrentit, another Grosbeak and a Hairy Woodpecker.  Only three warblers all day, one each of a Wilson's, Audubon's and Townsend's Warbler.
It was 44 species for the group of 8 participants.

I forgot about the Chipping Sparrow we saw at the Junction today.  It was at the upper part of the campground, maybe the second site around the loop.

Black-chinned Hummingbirds, Pleasant Hill, Lafayette, etc. (and Blue Grosbeaks Bethel)

Ethan Monk <z.querula@...>
 

Hi All,

It has become better known in recent years that Black-chinned Hummingbird populations exist in small numbers off Happy Valley Road in Lafayette and over a slightly larger area in West Pleasant Hill. The Contra Costa Breeding Bird Atlas ('98-'02) never documented any birds of this species in the general area, possibly either because of the species' extreme locality in the area/lack of coverage or a recent range expansion into these locales. Presumably the former is true, considering a year or so back, I had a conversation with a lifelong birder who spent his childhood years (the '80s, I believe) in Pleasant Hill (he now lives out of state) who mentioned recording Black-chinned Hummingbirds at his feeder multiple times a summer. I tried to refind the emails I exchanged with him to find a more precise location, that way I could check and see if they still summer and/or breed close by (I'm sure Black-chinned Hummingbirds still breed somewhere in the general vicinity) but could not recover the emails. Maybe I deleted them? Whatever the case, I was wondering if anyone who reads this has a) observed breeding evidence of this species in either Lafayette or Pleasant Hill or b) if anyone knows where I can find these birds without walking into private backyards so that I can attempt to confirm breeding, myself.

On another note, since I would like this thread to remain on EBB-Sightings so that it is visible to more people and not removed to EBB-Discussion (it seems rather superfluous to have two separate email groups that both discuss birds in the East Bay... We are the only listserve in the Bay Area--and possibly all of California--that actually segregates bird messages into different groups based on their subject matter) So, here are some bird sightings...

Sunday afternoon, I checked Bethel Island for any signs of migrant or breeder activity for a short hour or so. A quick report:
--On the West side of Bethel Road in the field immediately before the first willows shore up to the side of the road, there is a cooperative breeding pair of Blue Grosbeaks, countercalling. The male probably sings in the morning.
--The fields on the East side of Bethel Island Road that are flooded in winter remain flooded, although few shorebirds are currently using them. 3 Least Sands, 3 Killdeer, 3 Stilt and 9 Avocet.
--The bottlebrush at the end of Bethel Island road was productive as always hosting 5 Bullock's and 1 Hooded Oriole (no Black-chinned Hummingbirds to be seen).
--Piper Slough Willows were entirely devoid of migrant activity (probably partially due to the time of day) save Yellowthroats and one lingering basic plumaged Audubon's Warbler.

Good birding,
Ethan Monk

Mitchell Canyon trip report, 5-4-2019

Bruce Mast
 

Hello East Bay Birders,
Yesterday (Saturday), I led an enthusiastic group from Marin Audubon
Society on a 4 hour walk through lower Mitchell Canyon. We followed the
Globe Lily Trail on the way in and the main road on the way out. We birded
only as far as Red Road.

Migrant activity was as good as I've seen it. In the flycatcher department,
we had an Olive-sided, Dusky, Hammond's and Pacific-Slope, along with
numerous Ash-throated Flys.

In the warbler category, we saw and/or heard multiple Townsend's,
Orange-crowned, and Wilson's Warblers and we go pretty good looks at a
Hermit Warbler.

A pair of Western Tanagers was a nice treat as was a returning Lazuli
Bunting. A calling Swainson's Thrush was a personal first-of-season for me.

We got a brief look at a Selasphorous Hummingbird, probably female.

We got to observe behavioral differences of territorial versus migrating
Black-headed Grosbeaks. The territorial birds were, as one might expect, in
the tops of trees along the creek, singing their hearts out. A flock of 5
migrants, meanwhile, were upslope, foraging hungrily near ground level and
moving across the slope as a loose group.

Hutton's and Warbling Vireos were active but we didn't detect any Cassin's.
I suspect we needed to go further up-canyon.

Thank you to our photographers who contributed photo-documentation to our
outing. A complete checklist with photos can be accessed at
https://ebird.org/view/checklist/S55797005

Mitchell Canyon is part of Mount Diablo State Park. It drains the north
slope of the mountain and can be accessed via Clayton, in Contra Costa
County. There's a $6/car entrance fee. Gates officially open at 8 am but,
in the spring, the docent often opens it earlier. I arrived yesterday
around 7:40 and the gate was open and a half dozen cars were already in the
parking lot. Early morning birding is best.

Bird on,

Chabot Regional Park--Clyde Woolridge Entrance

Judith Dunham
 

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.
