FOS festival

wespey
 

Thursday I saw a FOS Double-crested cormorant at Lafayette Reservoir. Friday was a FOS Northern flicker in my yard. Saturday I had simultaneous FOS Golden-crowned sparrow, white-crowned sparrow, Hermit thrush and Oak Titmouse in my yard. The yard is in northeastern Lafayette, near Taylor and Withers.

Ardenwood Bay-breasted

Roy Carlson
 

The Warbler was still there at 2 PM today, in spite of the crowds and the fountain being turned off. There is still rancid, unappealing water in the base, and some in the broken figurine on top - both of which sources it visited while there. It also posed nicely a couple of times on top of the figurine. I saw none of the other recently reported birds in the 45 minutes I watched the fountain.
Ardenwood is closed on Mondays.

More Ardenwood Oct 8

Dave Weber
 

The Bay-breasted Warbler reappeared briefly at 11:20am at the fountain. At 12:30 in the dell, approximately eastish of the gazebo and southish of the house, there were a Tennessee Warbler and Nashville Warbler in the small trees with multi-colored fruits. There is a harvest festival continuing there today, with 1000 people, I estimate.

Tropical Kingbird - Heather Farm, Walnut Creek - 10/8

Paul Schorr
 

At 12:45, we had excellent views of the Tropical Kingbird when it perched on dead branches of a willow on the north side of the wooden railing which is located on the east side of the natural pond. We had seen the bird from the opposite side of the pond when it was perched, preening and fly-catching from a tall snag about 100+ yards north of the wooden railing. Our son from CO surprised us with a visit on Saturday and this was a life bird that we “promised” him. Whew!

Good birding,

Mike McClaskey and
I found a Lapland longspur at Ferry Park (just past Miller-Knox Regional Park, Pt RichMond) that was present until flushed by  a dog at 11:10 this am. It was feeding in the intertidal to the right of the remaining buildings by the fishing dock or NE of restricted area sign on fence. Bird flew towards dock and we haven’t refound it yet.

Update on the Avian Pox situation at Ardenwood fountain. 

I contacted the park administrator and naturalist yesterday about the issue and they have decided to take the immediate action to drain the fountain this (10/8/2017) to stop more birds getting infected by drinking from the contaminated water.

So please be aware the fountain situation if you are going to find the recent rarities at Ardenwood today or in the near future.  Also be aware It will be extremely crowded again today due to the Harvest Festival and there is a $10 fee regardless you are an EBRPD member or not.

Happy Birding,

Alan,

Thanks for leading the bird walk today.  Interesting topics covered today, as always.  Here are my photos from the walk:

The Green Heron did put on a good show today. Only additional bird I found looking at the photos was an American Robin.

Golden Gate Audubon Society First Friday Bird Walk, October 6, 2017, Tilden Nature Area, to Jewel Lake via the boardwalk and back by the road.

Friends!

Our theme today was Vultures, the Cathartidae family. As with hummingbirds, this now exclusively Western Hemisphere family did have members in Europe in the Eocene period, about 40 million years ago. California has three vultures, the Turkey Vulture (we had three today!), Black Vulture (seen in Marin and Sonoma counties in 2014, 2015, 2016 and 2017 but no East Bay records at eBird), and California Condor (the probably last wild one in the Bay Area was seen on the Stanford campus in January,1971). There are about 170 California Condors captive in the San Diego and Los Angeles Zoos, and about 270 out in the wild in California, Mexico and Arizona/Utah.

"Bird" o' the Day may have been two Ospreys that flew over the parking lot at the end of the walk: Bell Boeing V-22 VTOL aircraft, probably in town for Flight Week this weekend. Best Bird was the Green Heron at Jewel Lake, who posed for us for a long time. And the Red-breasted Sapsucker at the parking lot picnic table has possibly returned for the third year; this bird, photographed last year by Lee F., is featured in the Golden Gate Audubon Society calendar for 2018.

Here are the 41 species seen by 43 observers:

Wild Turkey 
Great Blue Heron 
Green Heron 
Turkey Vulture makes it official, three birds from our theme family!
Sharp-shinned Hawk 
Cooper's Hawk 
Red-shouldered Hawk

Ardenwood Farm (10/6/17) - 9-Warbler + Plumbeous Vireo Day

Jerry Ting
 

It's a 9-Warbler (Bay-breasted, Tennessee, Nashville, Yellow, Yellow-rumped, Orange-crowned, Wilson's, Townsend's and Black-throated Gray) plus Plumbeous Vireo day at Ardenwood Farm!  More than 20 birders/photographers enjoyed watching the Bay-breasted Warbler routinely came to the fountain every 40 minutes between 10:15 am - 4:05 pm.  Here is a shot of the bird:

https://www.flickr.com/photos/jerryting/36832751424/in/photostream/

 

At around 1:30pm a Plumbeous Vireo and the continuing Tennessee Warbler showed up at the same time. The Plumbeous Vireo is all gray above and shows very fainted wash yellow on the flank.  Here is a profile shot of the bird: https://www.flickr.com/photos/jerryting/37511310172/in/dateposted/


Around 2:20 pm a Nashville Warbler flew into trees behind the fountain and Mark Rauzon got a couple of shots of it.


I noticed that most of the birds that came to the fountain today have developed some kind of disease on the beak which most likely is caused by the water,  The Bay-breasted and Tennessee Warbler image took by Rudy 3 days ago (10/3/2017) didn't show any lump but they are both infected today.  I will report the problem to the park administrator and ask them to fix the fountain ASAP.


Please note that Ardenwood will have a special event this weekend and there will be a $10 entrance fee regardless you are an EBRPD member or not.  The park is open from 10:00 am - 4:00 pm.


Here is my complete eBird report with more diagnosis photos of Bay-breasted warbler and Plumbeous Vireo:

Bay-breasted Warbler continues

Aaron Maizlish
 

The Bay-breasted Warbler has put on a good show this morning, coming to the fountain four times between 10 and 12:30, delighting about one dozen waiting birders.  This is at Ardenwood Farm in Fremont CA.

The bird was first photographed on Tuesday, but not correctly identified until yesterday. So this is its fourth day here.  First Alameda Co. sighting in 20+ years.

Wildcat Canyon Birding

Alan Krakauer
 

No real rarities, but it’s bustling. The picnic area at the bottom of the Wildcat Staging Area Parking lot is great right now. I had 5 species of woodpeckers from one spot this morning, including Red-breasted Sapsucker. There’s one, maybe two groups of Acorn Woodpeckers that are actively plucking acorns from small oaks. There’s a short loop that starts at the port-a-potties and goes up to overlook the parking lot. There are a few small fruit trees (cherry?) with a lot of fruit that are attracting some diversity (most interesing was Western Tanager). Great views of all the bustle.

I also walked the Belgum loop from the Wildcat Creek Trail back towards Monte Cresta and back down to the Parking Lot. Fly-over White-throated Swifts and Pipits were new for me there. Highlights were getting all three nuthatches in Johnson’s Trees (the pine/eucalyptus patch on the ridge above the old Belgum site) and great looks at coyotes.

Weirdly missed some common stuff today (bushtit, house finch, song sparrow, mockingbird), but still a pretty nice list.

More Lewis' Woodpeckers

Jeff Acuff
 

Today on the Blue Oak Trail in Briones Park (trailhead at end of Gloria Terrace, Lafayette) there was a LEWIS'S WOODPECKER and a BLACK-THROATED GRAY WARBLER both within the first quarter mail of the trail.

Then later, farther down the trail and on my return hike, 6 LEWIS"S WOODPECKERS flew over headed southeast.

In over 15 years of walking this trail, these are the first LEWIS'S WOODPECKERS I have encountered.  

Good Birding

Western Meadowlarks in Heather Farm Park Thursday

rosita94598
 

The string of good birding continued for us this morning, as I found first one and then two Western Meadowlarks on the north ball fields at Heather Farm Park in Walnut Creek.  I was able to find Walt Duncan, who said he had assured good birding by leaving his camera home. Walt was at the wooden railing on the east side of the large, mostly natural pond when I found him and we headed towards the north ball fields.  It was at our arrival that we realized a second W Meadowlark was on the grass with the first and two Starlings.  We attempted to call our fellow birders Tracy Farrington and Fred Safier.  Tracy made it to the park, but the two birds of interest had already flown high and off to the south.  This might have been a patch bird for Tracy, and it is only the second time I remember seeing W Meadowlarks in the park; the first was a number of years ago on the south ball field.

While I was first talking with Walt and another morning park person at the wooden railing, we noticed some birds in the little tree next to the lawn with the small reddish berries.  I forget the name of the tree, but the Tropical Kingbird was in the tree with other birds including a Nuttall's Woodpecker.  The Kingbird liked this tree several years ago, apparently supplementing its diet with the berries.  The Yellow-rumped Warblers also like it, along with the White-crowned Sparrows.

I forgot on my earlier post. It was seen from the San Leandro Marina over the bay. Seen from near the small rocky island.
