Shell Ridge Ash-throated Flycatcher, Golden-crowned kinglet, warblers, Lazuli bunting

Alan Bade <alanbade@...>
 

Yesterday we went for a midday hike in Walnut Creek's Shell Ridge open space, starting at Borges Ranch (lower parking lot open, no problem social distancing). We looped around to Twin Ponds and Bullfrog pond and back. At Twin ponds, there's a small stream (water is getting low) that feeds the two ponds from the southeast with brush and trees on both sides. Here we saw; Ash-throated FC, Wilson's warbler, Orange-crowned warbler, Black-throated gray warbler, Nashville, Townsend's, a Cassin's vireo and a male Lazuli bunting. I think the Twin Ponds are a little tree-lined oasis in the grass covered hilltops of Shell ridge. While we ate lunch at Twin Ponds, a Golden-crowned Kinglet worked the oak above us. Later, near Bullfrog pond we saw another Lazuli bunting. At the start of our hike we ran into Dan Bylin (park ranger) who told us he had seen a Lazuli, so we were happy to also see them.

At Twin Ponds, we almost thought the Nashville was a MacGillivary's. We had seen MacGillivary's a lot in the eastern Sierras, so when we saw a gray headed, yellow bellied warbler with a standout white eye ring, we thought of MacGillivary's. I thought the gray hood went all around the throat and seemed a little darker than a Nashville's. But I don't know if MacGillivary's even come here or if so, much later. So I counted it as a Nashville and tricks of the understory lighting. Maybe it was a female or immature and so didn't have the fuller yellow throat. It was a pretty quick, though still full glance at the bird. Maybe I am after-the-fact imagining, but I thought the eyering was broken. Unfortunately, no photo of that bird.

List and mediocre photos here, I need a longer lens; https://ebird.org/checklist/S67338213

Has anyone seen MacGillivary's around here? Is it a later season arrival, if so? As someone whose enthusiasm exceeds my birding skills, I appreciate what I learn (and corrections) from this Sightings list!

Thanks, Alan Bade

Horned Grebe

 


I don’t think Horned Grebe has ever been noted breeding anywhere in California. They are expected in the Bay November through April.

Also, for sightings in San Francisco please use SFBIRDS @groups.io

EBB is for Alameda and Contra Costa.

Re: Roadrunner in Oakland

Alan Howe
 

Hi, all.

I went looking for said roadrunner this afternoon around 2:30 or so. Walked & biked all over the area, but no bird. (I thought I'd gotten an answer to my playing a rr sound on my phone, but it turned out to be a band-tailed dove in the distance.) There were plenty of house finches to be seen & heard, though, & a number of western bluebirds were hanging around the baseball backstop in Bushrod Pk. 

Stay healthy out there!

Walnut Creek local interest

This evening there was an Osprey feeding on a fish on a snag at the west side of the Heather Farm natural pond. One piscivore I have yet to see this spring at Heather Farm despite usually seeing one by mid April is Caspian Tern. No ebird reports either, though a couple have been reported recently to ebird for Ellis Lake in Concord.

A crisp white-striped White-throated Sparrow that I spotted on the creek trail in downtown Walnut Creek on 4/7 continues to be seen this week. Digibinned photos from 4/12 and more location details in here:

Northern Pygmy-Owl at the Tilden

Chris Carmichael
 

This morning I found a Northern Pygmy-Owl in the Tilden Nature Area, in a tree at the point where the two Packrat Trails take off just beyond the (empty) parking lot. Was alerted to the bird by the flock of small birds mobbing it. The owl was on a horizontal branch plucking feathers from a small bird it was holding. The rounded head and relatively long, banded tail were apparent. The mobbing birds included several hummingbirds, several Chestnut-backed Chickadees, a single Brown Creeper, several warblers and probably others. Eventually the bird flew off in the direction of Jewel Lake.

John Missing and I found Mitchell Canyon very active today from start to finish with high counts for Nashville Warbler (9), Hammond’s Flycatcher (17), Black-throated Gray (15) and Cassin’s Vireo (7). These counts are probably conservative as there was so much activity it was hard to keep track.  Other species seen included Western Tanager, Hermit Warbler and Ash-throated Flycatcher.  Little hummingbird activity (rumor has it they’re all hanging out at Garin Regional Park).  It’s actually very enjoyable in Mitchell Canyon now as there are few people willing to bridge the gap from the nearest parking .8 miles away to get in.

During a mid-day walk at Contra Loma R. P., I needed to retie my shoe.  When I raised my foot onto a bench, a bird flew within a few feet of my head, caught an insect and peeled off and landed on a nearby branch.  I was very surprised to see my FOS Ash-throated Flycatcher.  It remained perched and Nancy also had very good views.  As I studied the bird, I noticed movement in some branches behind the flycatcher and it turned out to be a FOS Wilson’s Warbler.  This activity was in the willows on the left side of the boat ramp.  

As we had made our way down the road toward the boat ramp, we saw as many as three pairs of Bullock’s Orioles.  One female was collecting nest material.

Heather Farm Park, Walnut Creek

For the past several days swallows have been particularly abundant over and around
the natural pond at Heather Farm Park. This morning was no exception. I would reckon the 
number to have exceed 100 birds, without fear of exaggeration. Most were Northern Rough-winged and
Violet Green Swallows. There were a few Barn Swallows and Tree Swallows in the mix.

Heather Farm is finally catching up with Spring. In the medium oaks on the west side of the pond,
between the canal and equestrian paddock, I found a Cassin's Vireo, Warbling Vireo, Black-throated Gray
Warbler, Orange-crowned Warbler, Wilson's Warbler, two bright Yellow-rumped (both Audubon), and a Common
Yellow-throat. On the east side, in willows near the viewing platform, there was a very bright ad well streaked
Yellow Warbler. I that same vicinity there was a Lincoln's Sparrow, and a Fox Sparrow

A great deal of Lesser Goldfinch twitter topped off my visit.

Good birding, good health,

new yard bird - calliope hummingbird

Jerry Britten
 

I staked out a hotlips salvia in our yard hoping for a rufous hummingbird to come by - a couple did, briefly, but then a calliope hummingbird made a few lengthy visits, offering a chance for some decent photos.  First time we've ever seen one here!

I also saw at least two male Calliope Hummingbirds, very likely at least one female Calliope, also, as well as good numbers of Rufous, Allen's, and Anna's.

Five different species definitely made this my best day ever for hummingbird watching in Alameda County.

Swifts

Rosemary Johnson
 

On March 27, I saw one lone swift flying above Pinole Ridge.  I was fairly sure that's what it was but not used to seeing them and since I only sighted one I put a question mark in my notes.

However, yesterday at Crockett Hills and today at Hilltop Lake I saw four swifts flying overhead at each location.  I believe these were all Vaux's swifts but, as I say, not used to seeing them.

Black-headed Grosbeaks back in force at Tilden Nature Area

Lee Friedman
 

Yesterday at the Tilden Nature Area Black-headed Grosbeaks were singing loudly from multiple places, but especially by Wildcat Creek Trail in the vicinity of Jewel Lake. When they arrive they have to work fast to establish their territories and secure their mates.
There was also other interesting activity. There was one new Mallard duckling on Jewel Lake (being guarded by its mother from two river otters also present). I stumbled upon a Red-breasted Nuthatch nest, and photographed the male bringing an insect to the female in the nest and their exchange of it. It took one second for the insect to go from the male's mouth to the females, shown in three photographs on my eBird report. 
 

Stay healthy, and good birding at a good distance from others.

Garin Regional, Calliope and other migrants

Philip Georgakakos
 

Hi East Bay Birders,

Today I followed up on Juli and Bob’s report and checked out Garin Regional and the Pride of Madeira flower patch outside of the entrance. 

I perused the flower patch before and after walking around Garin and got lots many Rufous, Allen’s, Anna’s and one definite Calliope hummingbird.  Also, two female Selasphorus birds which and could also have been Calliope.
Checklists:
I parked on Skylark Ct. and walked downhill to cover the Pride of Madeira. Bob and Juli reported parking on Clearbrook Cir. Both streets have no parking signs, has anyone had any issues with this or know of a safe spot to stow you ride and check out the hummingbirds here?

In the park I got great looks at a Grasshopper Sparrow, many Bullock’s Orioles, and two FOS Western Kingbirds. 

Beautiful morning with lots of activity and song throughout. Hope folks are getting out and enjoying the spring. 

Phil Georgakakos,
Oakland
