Date   

The Buena Vista Audubon Pelagic is SUNDAY Sept. 19th.

David Povey
 

Hello all Seabirders,
The Sept. 19th. Buena Vista Audubon sponsored pelagic is this Sunday ..
This trip is booked full and has a waiting list.
Those of you booked on this trip, please arrive between 6:00 and 6:20 a.m  at Seaforth Sportfishing Landing in Mission Bay.
 I would expect crowds even though the day boats will have departed, as a number of overnight fishing boats will be arriving.
Parking is free in front of the landing and on the street. 
**WARNING**, the parking lots on either side of the landing have become aggressive about towing unauthorized vehicles in their lots. Please be careful that you are parking in Seaforth Sportfishing Landings lot. This is marked off by a white line and sportfishing lot lettering on the pavement to the west and a berm to the east. Do not park in the Conference Centers parking to the east, or any of the parking to the west i.e. Seaforth Boat rentals lot and others. All the street parking is available, and spots should open up in the main lot, as boats arrive that morning. You may wish to carpool, or be dropped off to speed up the process.
Once parked, please check in at the Seaforth Sportfishing office. The office requires masks to be worn and social distancing in line.
Next, find our group outside on the patio area, to sign in on the boat's manifest. We likely will be over by the cafe's seating area to stay clear of the returning fisher folks.
Both the office check in  and manifest must be done and matched before we can depart, so it's important that both be done as quickly as possible !
Paul Lehman will start a brief orientation about 6:20, and we will board about 6;40-6;45. So again we will need to move right along.
The boat is the 80ft. Legacy There are three heads (toilets) on board. The Legacy has abundant seating to store your gear. Seating is available both topside, and on the main deck. Please do not store gear in the bow, or outside stern area. 
There are limited snacks and drinks for purchase.  I recommend bringing your lunch. I suggest a light windbreaker, hat, sunglasses, and sunscreen. I would recommend  applying sunscreen even if we are under overcast. Then it is also a good idea to stay hydrated. Motion meds should be taken prior to boarding if you need them
We will be offshore for between 10 to 12 hrs. We will plan on returning no later than 7p.m.
The weather and seas forecast is very nice at this morning's posting.
Those of you who are on the waiting list, and would really like to go, You may wish to come down to the landing early that morning. I usually run a couple of spots that cancel at the last minute, or no-show. 
No promises, but if you are there, ready to go, and a spot opens up. I'll get you on. Of course in the order you're on the waitlist. See me (Dave Povey, old tall guy, gray beard, and a red ball cap) at the landing's patio that morning. This offer is limited to wait list folks only!
Again as with all covid precautions if you feel sick, or show any symptoms before the trip, do not go!

Anyone want to do a quick 3 day birding trip for Xantu's?

Roger Uzun
 

I was wondering if anyone would want to share driving duties on a 3-4 day road trip to photograph Xantu's Hummingbirds down in San Ignacio, Baja California Sur.  It's about an 11.5 hour drive each way from San Diego.  There are feeders in the town and it's the common hummingbird in that area.

I plan on leaving Monday Oct 4th and returning either Weds Oct 6th or Thursday Oct 7th. 

Email me if you would want to go along to help with driving and gas.

Kumeyaay Lake - Harmful Algae

Andrew N
 

Just a heads up, the Parks Dept has posted signs at the East and West sections of the lake where you cross over warning of harmful algae in the water. The lake trail is still open so I'm not sure the severity of the problem but something to keep in mind.

Orchard Oriole, very early Pine Siskin, Tricolored H., Baird's & Pecs

lehman.paul@verizon.net
 

On Weds the 15th, there was a female-type Orchard Oriole in the TRV community gardens, starting out in weeds with House Finches. Be aware that there are also still 3 Hooded Orioles present in the gardens, two of which are juvenile birds with clean yellow underparts and a smallish bill. Also in the gardens today was an extremely early Pine Siskin. The earliest lowland arrival date for the county involve two records from 9 Sep from over 25 years ago. Also a female/imm Yellow-headed Blackbird at both the community gardens and at the Sunset ball fields. A Baird's Sandpiper was along the east edge of salt works Pond 22, off the end of 13th Street in Imperial Beach.

Also today, Dave Povey reports the continuing Tricolored Heron and 2 Pectoral Sandpipers at the upper end of Lower Otay Lake.

Harris's Hawk at Borrego

Nancy Christensen
 

Hello all, I made my weekly round of “oasis” spots in the desert this morning. Handfuls of migrants are showing up, but few in number and nothing exciting. Best bird today was a Harris Hawk at the Borrego Springs settling ponds. It flushed from the ground and flew off towards Ram’s Hill where I lost sight of it. It was not chaseable, so I did not get the word out right away,

 

Many areas of the desert received rain during our recent monsoon flows. There are large areas with leafed-out ocotillos, with small areas of flowers. Many of the Desert Willows are blooming along the washes. Hopefully the greenery will start attract some migrating birds!

We were there from about 8 to 10:15 and did not find it.  There were about 8 or so other people who came and went, checking around the rest of the park as well with no luck that we heard of.

California and Black-tailed Gnatcatchers at Oak Grove

Philip Unitt
 

Dear friends,

 

From 31 August to 2 September 2021, Lori Hargrove and I completed our first round of bird surveys of the California Department of Fish and Wildlife’s Oak Grove Wildlife Area. Acquired a few years ago, the area includes much of the floor of Oak Grove Valley in north-central San Diego County, including all of the wash of Chihuahua Creek, and some of the surrounding slopes.  Our most notable discovery: a new site for the California Gnatcatcher, at an elevation of 2800 to 3050 feet, higher than previously known. We observed two pairs along the wash of Chihuahua Creek and heard the species’ diagnostic calls at two other sites. I got a recording of the calls of one pair with my cell phone. So evidently there is a population, not just a wandering individual.

 

Not only does Oak Grove represent a new site for the California Gnatcatcher, it’s also a new site of sympatry of the California and Black-tailed Gnatcatchers. At two spots, the two species of gnatcatchers were in adjacent territories. Basically, what we found was an extension of the desert fauna that Ken Weaver described just 3 to 5 miles to the northwest at Aguanga in Riverside County and in Dameron Valley, straddling the county line (https://archive.westernfieldornithologists.org/archive/V42/WB-V42-1-Weaver.pdf). That includes, among the birds, also good numbers of the Cactus Wren (presumably the desert subspecies anthonyi), Ladder-backed Woodpecker (here overlapping with Nuttall’s Woodpecker), and Black-throated Sparrow. All these are resident on the coastal slope: Chihuahua Creek drains into Temecula Creek, which ultimately becomes the Santa Margarita River.

 

Among mammals, we noted several white-tailed antelope squirrels and among reptiles numerous juvenile zebra-tailed lizards, plus Lori saw one leopard lizard, all characteristically desert species also representing isolated populations here on the coastal slope. So we have already noted most of the species that make this area of unusual biogeographical interest. In his article, Ken Weaver called attention to the piecemeal development eroding the habitat supporting these isolated populations around Aguanga, so it is good news to find that a significant chunk of it has been conserved by CDFW.

 

We also noted the comparative sterility of the former agricultural fields on the valley floor now grown largely to mustard. Since we could not find a single California ground squirrel, we were discouraged over the possibility of the Burrowing Owl. Nevertheless, active rodent burrows were evident in some parts of the valley floor, so the search for the possibility of Stephens’ and Merriam’s kangaroo rats will be high priority for Scott Tremor when he makes his surveys of the area for mammals. The use of this habitat at other seasons is something to be investigated as well, but there is an opportunity for restoration of grassland, and some kind of restoration is part of CDFW’s eventual plan.

 

We have one 3-day survey per season scheduled for the upcoming year, so next spring and summer we’ll also focus on the question of persistence of the Gray Vireo, found in the surrounding area during field work for the San Diego County Bird Atlas 1997-2001.

 

A couple of weeks ago there was a little discussion of the fall migration of the Violet-green Swallow. On 1 September I saw 6 in Oak Grove Valley. Five were circling over the valley foraging so could represent postbreeding dispersal from nearby Palomar Mountain, but one emerged from the hills to the north and flew in a beeline to the south.

 

CDFW’s Oak Grove area is closed to the public, so our surveys through the San Diego Natural History Museum on behalf of CDFW represent a rare opportunity to explore this area to which we did not have good access for the bird atlas.

 

Good birding,

Re: tipus and lerpy eucalyptus

Susan Smith
 

Paul et al. , Concerning the drop in lerp infestations in eucalyptus, I read in one study (Dahlsten et al 2005) which measured the decline in lerp densities  in Southern California after multiple releases  (1999 through July 2002) of the biological control (the parasitic wasp,   Psyllaphaegus bliteus from Australia). They  found lerp densities  had decreased as much as 78-79% after these releases.   This was published in 2005, so I would imagine the decline in lerp densities since then may be even more.    We have noticed a big decline in densities at the San Diego Botanic Garden, too.  Sue

Subject: [SanDiegoRegionBirding] tipus and lerpy eucalyptus

My impression while birding and otherwise checking quite a few areas of
south county for the past several weeks is that almost all tipu trees
are fairly dead, bird-wise. Some years they seem to attract reasonable
numbers of warblers, etc., already by latter September, but other years
they are not good until much later. Last year, they were very slow until
almost mid-November. This year seems to be following that same scenario,
so far. And while last year was good for many patches of birdy lerpy
eucalyptus, this year seems to have substantially fewer infected trees,
and few birds. I can find only a couple patches (e.g., in Tierrasanta)
with active, fresh lerps, whereas many of last year's patches are not in
use and mostly birdless. It would be very helpful to other birders if
folks who DO find active, bird-rich lerp areas, let others know!

Oops. Correction. The trip is September 19, and I’m really disappointed I can’t make it.
Thanks David for the correction.


Seaforth Sportfishing birding trip #'s

I was looking for someone who might be interested in trading their October birding reservation for a September 18 reservation. I had a family emergency in Massachusetts and will not be able to attend.
I talked to Sterling at Seaforth who gave me the ok
