Re: Bell's Vireo - Pinned location

Melani King
 

The continuing Bell’s Vireo was seen yesterday at approximately noon at the location pinned by John Blakelock. It was and moving around in the willows, alternately preening and vocalizing.

Heather Farm Park Walnut Creek Monday June 11

I saw Fred Safier before arriving to the park today.  He told me he found an Ash-throated Flycatcher on the west side of the large, mostly natural pond.  The bird then flew in the direction of the equestrian rings.  I thanked him and spent quite a bit of time searching there from my bike, pausing, listening and looking.  I could not re-locate this bird.

The city is starting to clean the pond, having the large pond skimmer machine brought in today.  This is an annual event, sometimes it happens a second time later in the summer.  On occasion, the machine seems to be abandoned near the gravel boat ramp for long periods of time.  They ususally work on the concrete pond too.

Continuing Bell’s Vireo on Bradford Island, CC County

Patricia Mahoney
 

I visited the Bell’s Vireo on Bradford Island in Oakley, CA, this afternoon from 1:30 - 4 pm. I parked on the road shoulder near the ferry dock and walked onboard (alternatively, you can drive on to the ferry and on Bradford Island). It’s a short hop and a fun ride from Jersey Island to Bradford Island. After a half-hour stroll on the flat road I reached the aforementioned dropped-pin spot (OK cell signal) and heard the Bell’s Vireo singing! From the road, I walked down the grassy slope (a narrow birders’ “goat path” and a magenta sock tied to some grass were helpful visual aides!) to the edge of the fennel patch that’s in front of the willows and stood next to the barbed wire fence (cows are on the other side). The vireo was actively moving around the willows but sang persistently which helped me find it- and get a few good scope views, too. In between vireo sightings: Common Yellowthroat, Hooded Oriole, Bullock’s Oriole, Western Kingbird, Blue Grosbeak, Chat (several sang along the road and one flew out of the fennel and into the willows), American Goldfinch, Brewer’s Blackbird, House Finch, Raven, and Barn, Cliff and Tree Swallows... and Great Egrets and Black-crowned Night Herons along the water’s edge. While I waited for the 5 pm ferry, a river otter swam by, a Caspian Tern flew over and a Northern Harrier soared overhead.

I bought a ferry ticket ($8) at Gas N Save (Valero) on E. Cypress Road. From E. Cypress Rd. take Jersey Island Rd. to its (northeast) end for the ferry dock. As Logan mentioned, the ferry is on the hour and the last one’s at 5 pm. The ferry’s dockhand asked me if I’d found The Rare Bird: Yes!

A big Thank You to Mark and Lucas for finding the special vireo- and thanks to everyone for sharing info! It was my first visit to Bradford Island and I look forward to returning.

Bradford Is. Bell's Vireo and access

Dave Weber
 

After some early morning birding in Amador County, I planned to make the 10 am ferry crossing to Bradford Island, but construction on Cypress Rd prevented that. While waiting for the 11 am ferry two vehicles with Bradford residents got in line. I asked one gentleman about the island. He gave a lot of info, including that the residents on Webb Island are not so tolerant of strangers. He was intrigued by the vireo and apparently was unaware that birders had been visiting. No one said anything about Bradford being non-accessible, not even the Sherriff who was also there or the ferry deck hand or the guy at the Valero who sold me the ticket. At noon I found the Bell’s Vireo. It was almost exactly 8/10s of a mile from the ferry. A barbed-wire fence pointing downhill and a black pipe parallel to it point almost exactly to the vireo spot. I got in line for the 1 pm ferry back. One of the vehicles from earlier pulled up and a woman who was friendly wanted to know if I was DFW. Just birding I told her and said that birders had been informed that being on the island was OK. She said it was not, and that they pay a huge assessment to the county for their privacy. I totally agreed with her and said I would pass it on. Me… I won’t go back.  Thanks to those who found the bird… but just wondering who besides residents are actually allowed on the island? I could ask a lot more questions but won’t.

Since this is a threatened species in Calif. it's probably not a great idea for hoards to descend on it.

Hutton's Vireo Nest

Anne Krysiak
 

A pair of Hutton's Vireos built a nest on the crossbeam under my patio roof. We first noticed the birds working on the nest in early May. On May 25, the mama began sitting on the nest full-time. The male bird was hanging around. When he would call, she would leave the nest. This past Saturday, I noticed feeding behavior for the first time. It looks like both birds are feeding the chicks although only the mom sits on the nest. There were three eggs that I could see, but I have only seen two heads sticking up from the nest. 


I have pictures to share but am not certain how to upload them. 

Bradford Island access notes

Logan Kahle
 

Hi all,

With the recent discussion about Bradford birder access, I thought it would be relevant to chime in what I know about the topic.

As I am currently in the field, I am not able to research this as thoroughly as I would like. However, I still believe there is useful information here that would be of interest to potential visitors.

According to Department Engineer for the Delta Water District that Bradford is part of, the island ferry and the main levee road are entirely public property. I am still researching whether or not the roads through the middle of the island are public as well. As long as one does not trespass on private land on the island, which is not necessary to view the vireo or most other birds present, there should be no issues. As Dave mentioned, there are a couple specific individuals who do not take too kindly to visitors, but visiting the island is entirely legal granted one does not trespass.

As for the birds, it is of great import in my opinion to keep close tabs on this/these vireo(s). This is a state and nationally listed taxa, and as such breeding evidence could have a large number of conservation implications for the island. I visited the site on 6/9 and also had a Willow Flycatcher at the same location as the vireo. While almost certainly a migrant, Southwestern Willow Flycatchers, another listed taxa, once bred all the way up to Stockton (per Grinnell and Miller) in the 1940s. Should there be a Willow Flycatcher at this site in a week, it is very much worth keeping an eye out for any nesting activity (may be a bit of optimistic thinking on my end but heck, it is at the exact same spot as a Bell's Vireo...)

Anyway, I just hope none are too disheartened by a couple sour apples on the island. Landowners often, very reasonably, do not like people in the vicinity of their land, but in this case I feel the importance of keeping tabs on and documenting one of the most ecologically and conversationally important species in the Bay Area right now outweighs these concerns of privacy. The levee road is entirely public and any issues the neighbors have are personal and not legal matters. As such it seems reasonable to me that overall conscientiousness and respect towards the residents of the islands should be all that is needed. That said, this argument is moot if people are trespassing or otherwise exhibiting bad behavior, so please stay on the levee when on the island.

In any case, I hope many others get to visit the island in coming months. I was told that if being accosted by landowners ever becomes an issue, this is an problem that should be brought to the board of directors of the island to address. Please do mention if you have any issues with landowners. It would be great to make this situation as pleasant for the birders and residents alike. Ultimately, I believe this location is likely one of the top five or so  birding locations in the county and it would be a shame if people did not visit this under-covered gem out of fear of legal ambiguity. Good luck out there!

Good birding,

Rose-breasted Grosbeak

Kay Loughman
 

For the ninth time in the last twenty years, we've had a male Rose-breasted Grosbeak visiting our feeders.  This year it showed up on June 13, was not seen on June 14; but reappeared today (June 15).  Regrettably, this feeder is visible only from inside the house, and I have not been able to see where the bird goes when the scrub-jays assert themselves - (possibly Garber Park).  See  pictures on my website.

Bradford Island access issues, June 15th

Jeff Hoppes
 

 I birded Bradford Island this morning (Friday, June 15) in search of the Bell's Vireo. The vireo was singing at the previously noted location between 9:30 and 11. Shortly after 11 I and another birder were asked to leave by an island resident who told us that the willow patch with the vireo was his family's property, and that birding was not permitted at that location (even from the road), as the road itself was also private property. I don't have the expertise to evaluate the accuracy of that claim, but thought it was worth passing along to this list for the information of birders considering future visits to the island.

 Good birding,

Probably Costa's Hummingbird

Steve Huckabone
 

This morning while driving Mines Rd I stopped at a house that had 3 hummingbird feeders hanging from the second story patio. I pulled off the road the best I could and watched several hummingbirds coming and going. One looked good for an adult male Costa’s but could not get pic or good view. I got out of the car and walked along the shoulder to get a better vantage point and snapped a few pics of a sub-adult male. After I got home and looked at the pic’s I thought the one good pic showed a sub-adult male Costa’s. See eBird report https://ebird.org/view/checklist/S46615503. The interesting field mark is the gorget coming in at the corner of where the gorget will be eventually. I don’t have allot of experience with Costa’s but books and photos show this field mark and description for sub-adult male Costa’s.  The house is on the right side when traveling south from Livermore in the area where there is a small group of homes on both side of Arroyo Mocho creek. Sorry didn’t record mile marker. Feedback appreciated.

 

Good birding.

Marsh Creek and Big Break Trails--Good Raptors, Blue Grosbeak

Lee Friedman
 

Yesterday morning in Oakley I birded Marsh Creek Trail from E. Cypress Road north to the junction with Big Break Regional Trail and followed the latter west for 1 mile before returning. My realized hope was to see a Blue Grosbeak (along the Marsh Creek section), and I was pleasantly surprised by all of the raptor action in the large fallow area (former agricultural land) west of Marsh Creek and south of Big Break--3 American Kestrels, 1 Swainson's Hawk, 1 Red-Tailed Hawk, 1 Northern Harrier, and a coyote to boot. There was also a Cooper's Hawk on the Big Break side.

Osprey in the hood

Never seen one here in Maxwell Park, Oakland in 27 yrs. It was hauling something about the size of a squirrel down the street, stopped on a pole for a moment before a couple agitated crows chased it toward the flat lands - too quick for me to see its catch. Anybody missing a large carp?

Bradford Island

mskrentz
 

Four of us birded Bradford Island today arriving on the 9:00 AM ferry and leaving on the 1:00 PM ferry.
We heard the Bell's vireo singing on territory at the previously reported location. It also perched and return to the same perch on a bare branch fairly had in the willow. Seen well in a scope.

Unfortunately, it is no longer possible to drive the road in the middle of the island as on the southern side near the ferry landing, the gate on the road has been locked. On the northern side, there is a turn to the road near some houses; however about halfway down the island, another gate was locked and we had to turn around. The part that we did drive had high bushes on both sides so it was not that great for finding birds. It was much better on the levees.

We ran into the same person that Jeff Hoppes did and got the same message. The guy is about 60 years old and drives a red truck with a dog (border collie or Australian Shepherd type. He lives north of the vireo location past the other dock and his property is entirely enclosed with a wood fence on the right side of the road as you travel north with Eucalyptus trees near the fence. We ate lunch at that location and he drove up and said we would have to leave at first claiming the island was private. We mentioned that the levee road was public property and at first he said agreed but then claimed we were on his private property since he has an easement on the other side of the road. When I again mentioned that we had check with delta engineers, he said," Would you like to have me check that check that by me calling the sheriff." Tthat is really a idle threat as its an island and I doubt very much that the sheriff's department  are going to run out and take the ferry there to get someone off levee roads. However, to avoid further escalation we left while he stayed in his parked truck until we drove off.  He is a thoroughly unpleasant person who wants the island to be private. He mentioned that Webb Island didn't allow people to get off there and obviously wished his island was the same.

I had done some checking on the island before going. There are many parcels of land on the island, few houses and although they pay Contra Costa taxes on the properties  and a reclamation tax to keep the ferry open, this is one of the places that exists only because of tax payers keeping the levees repaired.

We also saw at least 5 Blue Grosbeaks and heard at least 4 chats.

The unpleasant person also has an old fire truck parked across the road from his house as well as a boat trailer I would suggest just not hanging out in that spot.

Also sorry about the typos; sent off too soon. To clarify the bird was fairly high in the willow.

WEST NILE VIRUS ACTIVITY INCREASING IN ALAMEDA COUNTY
The presence of both West Nile virus positive dead birds and mosquitoes in Union City warrants caution.
HAYWARD, CA - To date, Alameda County Mosquito Abatement District has detected 4 dead birds and 7 groups of mosquitoes which have tested positive for West Nile virus.  The birds were collected from Union City and Castro Valley. The mosquitoes were collected in Union City and Hayward.  Recent West Nile virus positive detections indicate heightened virus transmission in the Union City area west of Interstate 880.

Intensified efforts are focused on locating areas of standing water where the West Nile virus positive bird and mosquito were discovered. Residents are urged to be proactive by eliminating sources of water where mosquitoes can breed and protecting themselves from mosquito bites. If you come across a dead bird please report it by calling (877)WNV-BIRD or online at www.westnile.ca.gov.

"Infected mosquitoes in the area means there is is an increased risk for West Nile virus transmission to people," says Laboratory Director Eric Haas-Stapleton.  "Protect yourself and your family by applying mosquito repellent when spending time outdoors.  Containers of water in yards should be dumped and drained, or tightly covered to prevent mosquitoes from breeding in your neighborhood."

Mosquitoes may breed in almost any type of standing water including but not limited to catchbasins, stormdrain systems, and swimming pools. Neglected swimming pools continue to be a mosquito breeding issue in Alameda County.  If you or anyone you know has an unmaintained swimming pool please inform the District so the proper treatment can be made.
As of June 22nd, California has had 27 dead birds, over 30 mosquito samples, and 9 humans test positive for West Nile virus.  

Reduce the risk of contracting mosquito-borne diseases by following these guidelines:
  • DUMP/DRAIN standing water on your property because that is where mosquitoes develop.
  • DAWN/DUSK is when mosquito activity peaks, limit outdoor activities during this time.
  • DEFEND yourself from mosquito bites by wearing long pants and long-sleeved shirts and apply insect repellent containing EPA-registered active ingredients such as DEET, Picaridin, IR3535, or Oil of lemon eucalyptus.
  • DOOR/window screens should be in good repair with no tears or holes.
West Nile virus is transmitted to people and animals through the bite of an infected mosquito.  There is no cure for West Nile virus.  Approximately one in five people who are infected with West Nile virus will develop symptoms such as fever, headache, body aches, joint pains, vomiting, or rash.  Less than one percent will develop a serious neurological illness such as encephalitis or meningitis.  Adults over 50 years old and people with compromised immune systems are at increased risk of serious complications.  Anyone who develops symptoms should seek medical care immediately.

Horses are very susceptible to West Nile virus and vaccines are available.  Horse owners are advised to contact their veterinarians regarding timely vaccinations.

For information about mosquitoes, West Nile virus, or to request any of the District services visit www.mosquitoes.org or call (510) 783-7744. Residents can also request mosquitofish for their fish ponds, horse troughs, or neglected swimming pools at the the District office located in Hayward at 23187 Connecticut St.  For information concerning West Nile virus symptoms, prevention or testing please contact the Alameda County Public Health Department at (510) 267-8001.

A few Contra Costa birds Friday June 29

rosita94598
 

Heather Farm Park in Walnut Creek had three heron species this morning; 3 Green Herons, one of which appeared to be young, an adult Black-crowned Night-Heron and a Great Egret.  The Caspian Tern made an appearance between 7 and 7:30, also.  We saw three species of swallow, Barn, Violet-green and Cliff.

By 9:30, Rosita and I headed to the Orinda side of Briones Reg. Park to look for the eBird reported Indigo Bunting.  We arrived at the parking lot about 10 and started walking within a few minutes.  It is almost a one mile walk, slightly uphill, so maybe we were at the right spot by 10:30 or so.  Two birders from Fresno, Rick and George, had just seen it fairly close to the Abrigo Trail at the Maude Whalen Camp.  After 1-1/2 hours, it was finally re-located briefly by them and Rosita, but I was caught on the wrong side and missed it.

Maybe it will work for me another time.

Cooper's Hawk mobbed by hummers?

reintjesee@sbcglobal.net
 

On Sunday, a Cooper's Hawk flew past me about eye height in my backyard near Lafayette BART.  It was followed by three hummingbirds.  Does anyone know if hummers engage in mobbing behavior?  Or perhaps this was totally coincidental.  


Good birding
