Re: GGAS Tilden Nature Area Outing 10/5

Lee Friedman
 

During Alan Kaplan’s GGAS walk by the Tilden Nature Area and Jewel Lake, there was also a juvenile Cedar Waxwing perched under the Pacific-Slope Flycatcher. Cedar Waxwings are somewhat unusual for this area (only four other October sightings since 1996 at either Jewel Lake or the Nature Center). A photograph of the Waxwing (along with a number of the other species) is included in the eBird checklist:

Good birding,

Golden Gate Audubon First Friday Birdwalk 10.05.18 Tilden Nature Area

Alan Kaplan
 

Friends!

Golden Gate Audubon Society First Friday Birdwalk, October 5, 2018. Tilden Nature Area, parking lot to Jewel Lake and back by way of the boardwalk.

Topic today was again feathers: Ptilochronology (the study of feathers through time), growth bars (the growth cycle of a feather is marked off each 24 hours by a dark [daylight-deposited] and light [night-time deposited] pair of bands), and is evidence of the nutritional status of the bird during the feather's development. The field is only 30 years old (Thomas Grubb's first paper using ptilochronology was published in 1989) but there is enough research that Grubb published Ptilochronology: Feather Time and the Biology of Birds (Oxford University Press), in 2006.

Here are the 34 species seen by 40 observers:

Canada Goose 2
Wild Turkey 3
Anna's Hummingbird 2
Great Egret 1
Turkey Vulture 1 makes it official!
Red-shouldered Hawk 2
Hairy Woodpecker 1
Northern Flicker 1
Pacific-slope Flycatcher 1
Black Phoebe 2
Hutton's Vireo 3
Warbling Vireo 4
Steller's Jay 1
California Scrub-Jay 1
Common Raven 2
Chestnut-backed Chickadee 2
Oak Titmouse 2
Red-breasted Nuthatch 3
Brown Creeper 4 Bird O'the Day: lots of singing!
Bewick's Wren 1
Wrentit 1
Varied Thrush 1
Hermit Thrush 1
American Robin 3
Lesser Goldfinch 5 feeding on thistles on the Jewel Lake sandbar
Fox Sparrow 1
Dark-eyed Junco 5
Song Sparrow 2
California Towhee 3
Spotted Towhee 1
Yellow-rumped Warbler 3
Black-throated Gray Warbler 1
Townsend's Warbler 1
Western Tanager 1

November’s theme is, of course, Wild Turkeys!

Best of Boids!

New yard bird - Black-throated Gray Warbler

Derek
 

I'm typically birding from my bike so I don't into the woods a lot to
find warblers, but this fall I have hit the woods and seen an
abundance of Black-throated Grays. And today, a minute after i took a
seat in my patio to do some work, i heard the chip note of one and
quickly rushed over to see it before it flew off into the neighbor's
yard.

New yard birds are not easy in this area so it's a nice start to the weekend.

I saw my first GCSP this morning at my feeder in Castro Valley. Nothing says "Autumn" in the Bay Area like the 3-note song of the GCSP!


Walnut Creek birds Wednesday Oct. 3

The Tropical Kingbird was seen by at least three of us this morning.  Rosalie, Tracy and I were under the large oak on the west side of the pond, when Tracy asked, "Isn't that the Tropical Kingbird?"  Across the large, mostly natural pond and in a leafless tree above the wooden railing, sat our bird.  I raced around the pond on my bike to see it better.  It was gone by the time the other two arrived.

While it seemed much quieter in the park today, we still found plenty of Yellow-rumped Warblers, and at least one Yellow and one Orange-crowned Warbler.

Re: Fw: The sound of the Great Horned Owl LOCATION - Oakland Laurel 10:20PM to after 11PM

We are at Kansas near Maple and I heard her last night and three nights ago she sounded like she was in our backyard. We have a tall redwood.  I wonder where she roosts in the daytime?  We sure have a lot for her to eat in our yard with young skunks, raccoons, opossums, squirrels, rats, but they are my friends!!!

I have lived in my Oakland neighborhood since 1995. I think this is the first time I have ever heard an owl. This is the call of the Great Horned Owl. Repeated 3 times over the waveform.

A group of 21 Sandhill Crane in v-formation overflew the project area in the north Livermore Valley.

Its been 15 years since I last saw them in Alameda County. That was a flyover in spring at Lake Del Valle.

Pt. Pinole, Sunday, September 30

Sheila Dickie
 

Yesterday, September 30, early afternoon in the old parking lot I talked to a group of birders from Sacramento who had just finished birding the Point Pinole Regional Shoreline Park and had either 57 or 59 species including a Barn Owl flying near the Dotson Family Marsh.

I birded all afternoon: did not quite catch up to that number and did not see the owl. Brief summary of species follows:

At the pond off Owl Alley: 5 sparrows: Fox, Song, Lincoln's, White-crowned and Golden Crowned. Also Willow Flycatcher and Hermit Thrush.

Elsewhere: Two White-tailed Kites flying above the marsh opposite the pond on the Bay Side. One Osprey flying above them and one Osprey at the pier, sitting on the osprey nest. It took off toward Marin, and I lost sight of it. Throughout the park a few Yellow-rumped Warblers, White-crowned and Golden-crowned sparrows.

One Say's Phoebe in the rough meadow adjacent to the new Atlas Parking Lot the lawn/mulch area of which is a magnet for Western Bluebirds, House Finches, Lesser Goldfinches and Yellow-rumped Warblers.

Not in Moraga though, which is why this is exciting, for those of us in Oakland, Berkeley, Alameda, etc.

These are fairly common out here in San Ramon and Livermore.  I see them often
