Male Barrow’s Goldeneye at Riverbanks WTP

Jim Rowoth
 

While checking some under-birded locales, i found a male Barrow’s Goldeneye at the Riverbanks WTP, which is adjacent to and N of Jacob Meyers Park. (The town is in Stanislaus Co, but the park & WTP are in San Joaquin). The bird is in the very first pond to the W of the office with coots, Common Goldeneyes & Buffleheads.

Thanksgiving Day Backyard Birds

k foley
 

Sixteen species of birds graced our yard with their presence on this windy but incredibly (if not ridiculously) beautiful day. These included Orange-crowned warbler, Bushtit, Cedar waxwing, Red-breasted nuthatch, Lesser goldfinch, Dark-eyed junco, Yellow-rumped warbler, Ruby-crowned kinglet and (yes, Jim) House finch.

I hope you all enjoy your Thanksgiving this year even if, like ours, it is smaller this year.

Four-Eagle morning at Flood & Waverly

Susan Schneider
 

Little did I think, when I watched eagles fighting over a carcass on PBS Nature last night, that I'd be enjoying the same spectacle in person this morning.  Flood & Waverly continues to have orchards replacing grassland, but there's still good habitat for our wintering raptors.

I started out at Rt 4 and south Waverly, and fairly quickly flushed a Prairie Falcon (which obligingly showed its dark axillaries) and then admired a foraging Ferruginous Hawk. Redtails and one Kestrel were also already active;at 35 degrees when I first arrived, I was rather surprised to see this much activity from the get-go.

As I headed closer to the intersection with Flood, I found another Prairie Falcon (another adult), and another Ferrugi.  Then, on Flood, I noticed a large eagle-like bird in the distance to the north.  Getting out of the car, I flushed a Burrowing Owl I hadn't noticed.  And indeed, to the north I was pleased to spot four Bald Eagles: one juvenile, one third-year, and two adults.  They were taking turns and squabbling with each other, and with a large number of Ravens, at what appeared to be a cow carcass. 

On my way east on Flood, a bird on a low fencepost turned out to be a very blotchy juvenile Prairie Falcon, my third of the morning.  In the car, I was able to get within 30 feet for marvelous views.  (Unfortunately, while I'd remembered to bring my camera, the battery was dead.  Hey, nothing's perfect.)  I also enjoyed a briskly trotting Coyote around this time. 

The final raptor highlight came when I was heading north again on Waverly:  The juvenile eagle flew over and displaced a Ferruginous Hawk from a fencepost.  Ferruginous Hawks are big, but the eagle made it look small!

Happy Thanksgiving,
Susan

Folks (as our Pres-Elect would say),

 

I was just looking at the Illustrated Checklist of birds for San Joaquin Co (https://ebird.org/region/US-CA-077/media?yr=all&m=), I found the following species do not have a photo attached.  Many of these are historical one-time records.  However, I am sure there are photographs of some of these birds out there.  Remember, eBird does not require that photos be “gallery quality”—as long as they show enough to ID the bird, that is sufficient.  

 

Thus, I am requesting, if any of you out there have photos of any of these species, that you attach one (or more) photo(s) of these birds to your existing eBird report or that you submit a list in eBird showing that species in San Joaquin Co.  Remember, checklists can be either “complete” or “incomplete” as far as species composition is concerned, and that, in addition to Traveling and Stationary, you can submit an Incidental or Historical report.

 

Thanks in advance for your help in plugging some of these holes!

Stockton Rural Cemetery

Jim Rowoth
 

I spent a pleasant morning at the old Stockton Rural Cemetery today, (eBird list https://ebird.org/checklist/S76052130).  Not a great variety of species, but lots of individuals.  Early on, I had an apparent family group of three coyotes trot by me among the tombstones.  During the 3 hours I was there, I saw at least one about every half hour.  I‘ve seen singletons before, but never 3!

It is always a good idea to keep your eyes open for leaky spigots here, and this morning there were multiple leakers.  Given the overall dry, dry, dry conditions locally, these spigots attract a lot of birds and other wildlife.  Almost every one had some activity.  

I spent the entire morning look for Red-breasted Sapsucker, but didn’t see one until I was in my car driving out—in a pepper tree, as expected.

Lodi Lake today

Pat Paternostro
 

All 
I birded LL this morning on a cool and breezy day. 
Highlights included:  A seemingly lost Snow Goose, following domestic white geese on the lake.  Townsend’s and Black-throated grey Warblers on Laurel Ave.  I heard a couple Varied Thrush and finally watched an Osprey catch and eat a Crappie. 
44 species in total. 
Lastly, there’s a couple days left to bird at the lake in preparation for our DIY follow-up.

SJ Audubon Zoom Gen Meeting Tues Nov 10: "Birds, West Nile Virus and the Mosquito Connection"

England
 

TUESDAY, November 10, 7:00 p.m.

ZOOM MEETING LINK:

https://us02web.zoom.us/j/87650154751?pwd=eHIzU0RXaEE0c09ZWnF3RC93YlF3Zz09

 

Dr. Tara Thiemann

Birds, West Nile Virus, and the Mosquito Connection

 

West Nile virus was introduced to the United States in New York in 1999 and, by 2003, it had spread across the country and was detected in California. It has since remained endemic throughout the country and state.  West Nile virus is a mosquito-borne virus that primarily infects birds, sometimes decimating populations.  Additionally, with opportunistic feeding by mosquito vectors, the virus can be transmitted to mammals such as horses and humans. Host selection by these mosquito vectors is a crucial factor in the transmission of this virus and other pathogens. The goal of the current project was to characterize the feeding patterns of Cx. tarsalis, the Cx. pipiens complex, and other mosquito species according to habitat type in San Joaquin County. Over 600 bloodfed females were collected from different habitat types between August 2009 and November 2012. Over 80% of the bloodmeals were successfully identified. These bloodmeals represented 77 host species: 44% were mammalian and 56% were avian, with being collected from riparian and agricultural habitats. Overall, the most commonly fed upon species were cattle, house finches, and American robins. American crow, yellow-billed magpie, and California scrub-jay, species known to be highly impacted by West Nile virus, were also fed upon in this study.

 

Dr. Tara Thiemann is an Associate Professor of Biological Sciences at University of the Pacific. She was born and raised in Missouri, receiving her B.S. and M.S. in Biology at Truman State University in Kirksville, MO.

 

She then moved to California to pursue graduate work at University of California Davis. Dr. Thiemann graduated from UC Davis in 2011 with a Ph.D. in Entomology and a Designated Emphasis in the Biology of Vector-borne Diseases.  Her dissertation focused on the bloodfeeding patterns of the Culex pipiens complex and Culextarsalis, two primary vectors of West Nile virus in California.  At Pacific, Dr. Thiemann continues to study mosquitoes, while training both undergraduate and graduate students in her research lab.  Projects include continued exploration of the bloodfeeding patterns of California mosquitoes, studying the transmission of dog heartworm, and characterizing insecticide resistance in local populations.


Bear Creek bike trail

Susan Schneider
 

Nan Ballot and I enjoyed these highlights this morning:  about 160 each Sandhill Cranes and White Pelicans, a huge flock of 300 Long-billed Curlews, plus one small skein of Snow Geese.  The weather was beautiful and the air was clean.

Good birding,
Susan

Surf Scoter remains in NE pond (not NW pond). Don’t you hate it when people get their directions wrong!!!

I dropped by to see if anything of interest was blown in by today’s winds. The female Surf Scoter found by David Yee on 26 October continues in the NW pond (closest to birder parking area). It was loosely associating with Northern Shovelers. I saw one female scaup in the SW pond; it appeared to have a peaked shape to its head, so I am assuming it is the Lesser that others have reported here. No trace of any other scaups, but I was only there about 1/2 hour and only walked around the NW pond.

Ponds that are near full—NW, NE, SW. The SE pond is choked with weeds, with scattered puddling.

I had my FOS Varied Thrush and Pacific Wrens at Lodi Lake this morning. It was a beautiful morning for a walk around the nature area. A lot of other people thought so too...

Good birding,

Reminder: San Joaquin Audubon Do-It-Yourself Birding Meeting Thurs Oct 29

England
 

JOIN SAN JOAQUIN AUDUBON FOR A NEW KIND OF FIELD TRIP:  “DO IT YOURSELF (DIY) FIELD TRIP”

Here’s how it works: 
·      SESSION I (Virtual) (Thursday, October 29)  A Zoom meeting with the field trip leader.  For this first time out, Pat Paternostro will introduce a local birding site—Lodi Lake Nature Area—and the birds you’re likely to see there, such as  Wood Duck, Hermit Thrush, Coopers Hawk, Ruby-crowned Kinglet, Fox Sparrow and Yellow-rumped Warbler. (Birders of all levels are welcome).
·      SESSION 1+ is the DIY part:  before the next Zoom meeting, you visit the birding location, where you’ll look for the listed birds and other wildlife.  Take binoculars and a bird field guide if you have them and keep a list of your observations.  Please follow all COVID-19 precautions when you are in the field: wearing masks, observing social distancing and hand washing.
·      SESSION 2 (Virtual) Usually the third week after the first meeting,  participants join again on Zoom, sharing what they found, and there will be an introduction to the next DIY field trip location.

 Here’s the information for the first zoom meeting, Thursday, October 29:
