White-tailed Kites nesting in Walnut Creek

pheagy2002
 

I live on a cul-de-sac on Mendota Ct in Walnut Creek, near the intersection of Pleasant Hill Rd, Geary Rd. and Camino Verde.  We have had a lot of nesting activity this year, and today I finally figured out that the squawking noise I was hearing were at least 2 fledgling White-tailed Kites. There are a lot of tall pine trees in the neighborhood, and they were flying from tree to tree.  I believe they may have nested in the Pines between Mendota Ct and Camino Verde.

The Yellow Billed Loon was NOT seen between 715-1020. I walked half down the north side without seeing the loon. Was able to scope the NE corner. Maybe in SE corner?

Subject: [EBB_Sightings] Possible The yellow-billed loon (Gavia adamsii) in Contra Costa Co.

 

 Yesterday, 5/23/2014 conducting observations on Clifton Court Forebay I found a possible Yellow-billed Loon, however please be noted id is not yet confirmed. This and other observations from this location in the eBird checklist (including pictures of the loon). Most local rarity I've seen in the eastern part of the Forebay, however, the loon was seen in the northern part. For those who are not familiar with this area, please refer to the map included in the eBird checklist, enter the Clifton Court Forebay from Clifton Court Rd. off Byron Hwy. 

Good birding,

Albert,
I checked the photos and can state that the bird is a Yellow-billed Loon.  Very nice find and only the second record for the entire Central Valley.  I'll plan on looking for it tomorrow.  If you are unsure of an ID, you can always contact me directly with photos to review in a timely fashion.  I drove near that location yesterday on my way home and if I had known about it then, I would have been able to stop and see it.

congrats again on a great record....keep it up!

This week the Mt. Diablo Audubon Society conducted its annual "No Child Left Inside" field trips to Contra Loma R. P. in Antioch. On Tuesday, 5/20. and today the fifth grade students had the opportunities to observe a total of 43 species over the two days.

Highlights included:

a female Great Horned Owl guarding two nearby fledglings
a Red-shouldered Hawk nest with 3 chicks and parent birds bringing food
a Golden Eagle that was being harassed by a Red-tailed Hawk
American White Pelican
Green Heron
Belted Kingfisher
Bushtit nest with parent birds attending
Swainson's Thrush
4 warbler species: Orange-crowned, Yellow, Wilson's and Common Yellowthroat
Warbling Vireo
Bullock's Oriole
nesting Western Bluebirds and Tree Swallows

In addition, volunteer Maury Stern, found a very docile gopher snake and delighted young and old with his herpetology lesson and hands-on experience.

Some of the students and volunteers were surprised by a nearby striped skunk that was working its way down the lake shore.

A big thanks to the fourteen MDAS volunteers for all of their contributions!

Good birding,

Magpie at Mt. View Cemetery??!

debbie viess
 

I headed up to the top of Piedmont Ave. yesterday, to check out the late afternoon bird life, prior to hitting my fave Piedmont Ave. Vietnamese restaurant, Xyclo, for my supper.


Lots of birdlife was already having their supper. 


As I drove along the upper reaches above the Olmsted reflecting ponds, heading for the southern side of the cemetery and those now almost dry holding ponds, I saw a big bird flying over the oaks at the top of the dry hills to the east … it had a very long tail, and a contrasting white breast. By the time I grabbed my binocs to glass it, it had disappeared into the greenery.


Other than a magpie, what else could it have been??!


Color me surprised.

Contra Costa county 5/15/14 and 5/18/14

Logan Kahle
 

Hi all,
On Thursday (5/15), after finding out about the Laughing Gull (which, for those who care, is just the second county record!), I decided to bird the Richmond bayside. I was also hoping to run into the three Red Knots reported in previous days, but those had apparently left too. At a bout 8:30, an unusual honking from behind lead me to a lone ROSS'S GOOSE flying north over Meeker Slough before it turned around and headed south. Aaron Maizlish and I were both able to get good photos as it flew right by us. This may represent the latest county record for this species (anyone have later dates?) and was totally unexpected.
Highlights in the first three or so hours of sunrise were (aside from the goose):
Black-crowned Night-Heron-5
Whimbrel-7
Long-billed Curlew-9
Willit-1
Marbled Godwit-20
Dunlin-2
RED-NECKED PHALAROPE-1 (heard calling at Pt. Isabel but could not locate the caller)
White-throated Swift-1


On Sunday (5/18), Cedric Duhalde and I got to the bayside before sunrise. Our best birding during our hour-long bayside tour was at Miller/Knox (Pt. Isabel yielded only two Whimbrel). At Miller/Knox, the highlights were:
American White Pelican-5
Osprey-1
Western Tanager-1

After that, we helped Denise Wight lead a Mount Diablo Audubon Society young birder club field trip to Inspiration Point. We stayed along the east side in the EMBUD area to avoid the swarms of people and the blasting west winds. Highlights included:
Acorn Woodpecker-1
Hairy Woodpecker-2
Olive-sided Flycatcher-1
Red-breasted Nuthatch-1
Pygmy Nuthatch-10
Townsend's Warbler-1
MacGillivray's Warbler-1 (a singing male that displayed very nicely for the entire group)

Cedric and I then headed east. We first stopped at Waterbird Regional Preserve. As expected at this time of year, if was very slow, and the only highlights were:
Cinnamon Teal-1
Northern Shoveler
COMMON GOLDENEYE-1 lingering bird
Great-tailed Grackle-6

At Iron House Sanitary District, we found:
American Wigeon-3 late birds
Cinnamon Teal-1
Forster's Tern-3
Black-chinned Hummingbird-2
Western Kingbird-2
Yellow Warbler-4
Townsend's Warbler-1
Western Tanager-1
Hooded Oriole-1

On to Bethel Island, we found a few birds of interest, mostly more valley specialties:
Ring-necked Pheasant-1
Cattle Egret-5 flybys in groups of 2 and 3 at Piper Slough. Apparently somewhat rare here.
Swainson's Hawk-2
Western Wood-Pewee-1
Yellow Warbler-1
Black-headed Grosbeak-1
CALIFORNIA TOWHEE-1 calling bird from Piper Slough. Per Steve Glover, this species used to be an exceedingly rare bird in East County, but I believe its range has expanded eastward in recent years. I had one at Big Break last fall, too.
Hooded Oriole-4

At the Holland Tract, we found:
Ring-necked Pheasant-1
Swainson's Hawk-1
Blue Grosbeak-1

We went on to the Byron Airport Preserver, which was totally windblown. Nonetheless, we managed to find:
Loggerhead Shrike-1
Horned Lark-1
Tricolored Blackbird-3

Clifton Court forebay was dead, but the Byron WTP was a little better:
Bufflehead-1 straggler
California Quail-1

We wrapped up at Dow Wetlands Preserve with:
Green Heron-1
Northern Harrier-1
Cedar Waxwing-10
Great-tailed Grackle-4

A final tally for the raptors that we kept track of:
Swainson's Hawk-14
American Kestrel-16
Northern Harrier-1


Another fun day in Contra Costa.


Good birding,

Piedmont White-tailed Kite

In the winds that swirled near sunset, a White-tailed Kite landed on top of a tall pine near Dracena Park in Piedmont.

For me, it was rare to see them this far from their regular grounds.

Mt.Diablo Burn Zone Alive, Alive-O!

debbie viess
 

Last Friday, my husband David and I drove up onto Diablo to see the post-burn wildflowers, and managed to see plenty of bird-life, too! As one would expect, there were plenty of woodpeckers working the burn and the surrounding, unburned trees: a Hairy, Nuttalls and plenty of those industrious and sociable Acorns.


We saw Ash Throated flycatchers, and heard Pacific Slope and various other Empids. The undergrowth was lousy with Swainson's Thrushes, with their distinctive buffy eye rings and over-all rufous backs. Western bluebirds brightened up the day, Scrub Jays scolded and I heard that high-pitched zeeeeeeing of Gnatcatchers.


But the botanists ruled. No matter how sad it is for us to see our landscapes burn, we need to remember that fire is a natural part of things, and those chaparral environments are designed to thrive after a fire. That was certainly the case on Devil's Mt., where all of the burned trees (live oak and bay) and shrubs (manzanita and chemise)  were sprouting new basal growth, and the ground was covered in post-burn wildflowers, some unseen for decades!


I heard an awful lot of muttered latin names along some of those trails, as giddy botanists argued over what they were seeing. Shades of mushroom geeks! Way too late and dry for any fungal activity in that burn, though.


I would recommend getting up high on that mountain and seeing all of the renewed life for yourself. It is quite heartening. And the same is true for the otherwise tragic Yosemite Rim fire. Not just our coveted Black-Backed Woodpeckers are drawn to those burn zones.

Pacific Commons (5/16) - Yellow-headed and Tricolored Blackbird

Jerry Ting
 

This (5/16/2014) afternoon I birded Pacific Commons Linear Park from 6:15-7:45PM.  Highlights include:
 
Yellow-headed Blackbird (1) - adult female seen perched on the fence along the paved trail (in front of 2 benches) southeast of the small pond (pic Yellow-headed Blackbird (female))
Tricolored Blackbird (1) - adult male seen perched on the fence south of the small pond (pic Tricolored Blackbird (male))
Green Heron (1) - adult seen on the northeast corner of the large pond.
 
No signs of Burrowing Owl, White-faced Ibis and American Bittern though.
 
Happy Birding,

SFBBO Bird Sound workshop - late June.

Alvaro Jaramillo
 

Hi folks,

 

  June 25, 26 and 29 I will be teaching a workshop (in Redwood Shores) dealing with bird song, how to learn bird voices as well as understanding its ecology and function. We will be using spectrograms to learn sounds, facilitating visualization of bird song. The workshop will also touch on how to learn sounds at home, resources that are available and how to use them. In the field we will learn about bird recording as a way to learn songs, in addition to good old focus and listening to learn bird sounds. Please visit the SFBBO website to obtain more details on how to sign up.

Laughing Gull (leucophaeus atricilla) in Richmond, Contra Costa Co.

albertlinkowski
 

Dear friends in birds,  two days ago while on observations in Meeker Slough area (Richmond, Contra Costa County), unexpectedly, I was rewarded with an unusual finding, there was a adult Laughing Gull (leucophaeus atricilla) in alternate plumage, and this is quite a rare bird in California, as you may know (except perhaps the Salton See) not to mention Contra Costa County. I enclose eBird checklist with pictures, when you open a link in any of the attached ones, you can access more photos of this species from this observation. For potential searchers, I suggests to look for the bird in the area between Richmond Marina and Point Isabel Regional Shoreline

Good luck in finding the bird,

Coyote Hills Regional Park, 5/15/14, Hammond's Flycatcher

Robert Furrow
 

This morning I birded the area around the visitor center and Hoot Hollow at Coyote Hills RP, from 9:50am until a bit after 11am.


My big highlight was a Hammond's Flycatcher at Hoot Hollow.  It gave easy viewing, showing a small bill, gray head with shaggy crest and teardrop eye-ring, gray-green back, and long primary projection combined with moderately short tail to give a short-tailed impression.  Other migrants in the area were 5 Wilson's Warblers, 1 Orange-crowned Warbler, 3 Yellow Warbler, 3 Warbling Vireo, 1 Western Wood-Pewee, 7 Swainson's Thrush, 1 Western Tanager, 1 Black-headed Grosbeak, 1 Lazuli Bunting, and 1 flyover Hooded Oriole.  Nearly all of these were around Hoot Hollow, and a Great Horned Owl even shared a single hooting phrase!  The full list is here: http://ebird.org/ebird/view/checklist?subID=S18403592


One of these days I need to get out there earlier in the morning!


Happy birding,
