North American Birds - Summer Season 2019

Guy McCaskie
 

County Coordinators/Contributors:

The Summer Season (1 June through 31 July 2019) is ended, and we solicit reports for inclusion in the Southern California Region of NORTH AMERICAN BIRDS. Reports should be arranged with species in the taxonomic order followed by the American Ornithologists Union (Check-List of North American Birds 1998 and all Supplements) and the American Birding Association (7th edition of the ABA Checklist, 2009 revised through 2018). Reports of species included on the California Bird Records Committee (CBRC) review list

http://www.californiabirds.org

must be accompanied by documentation (written description, photographs, etc.). Similar documentation should also accompany reports of species unusual for the location or season. Full names, with all initials, should be used in the reports (this reduces the potential for different observers having the same initials, and makes it simpler to acknowledge contributors) – John P. Doe in lieu of John Doe.

Reports should be sent to the appropriate County Coordinators (listed below) or directly to Guy McCaskie by 24 June 2019. NORTH AMERICAN BIRDS can not exist without your input.

buntings, murre, & miscellanea

lehman.paul@verizon.net
 

On Tues the 6th, at least one Indigo Bunting (the pale-bellied male) continues at the horse staging area parking lot just west of the B&B Garden in the TRV. It is in fairly heavy molt so is doubtfully going anywhere soon. A fall migrant arrival Lazuli Bunting was in the Tijuana River channel. At least one Burrowing Owl continues well ESE of the end of 13th Street.

There's been further expansion of the garden plots at the Community Gardens along Hollister Ave. in the TRV so that the acreage is now about triple what it used to be (both good and bad!). The habitat looks good now all the way to the westernmost plots.

On Monday the 5th, an early-morning seawatch at La Jolla produced 1 Common Murre, 2 Brown Boobies, 2 Cassin's Auklets, 1 Parasitic Jaeger, 800 Black-vented Shearwaters, and 25 Black Storm-Petrels. During the past several years, the rather unusual but recently annual July push of southbound murres has typically dried up during circa. the first half of August.

Encinitas White-winged Dove (8/7/19)

Jimmy McMorran
 

Hi Birders,
A surprise visit of a White-winged Dove was at my one of my back yard water features a little bit ago. It hasn’t returned, but haven't put much effort into waiting to see it again. It seems to now be an annual yard bird at this time of year. Anyway, they are moving.
Good Birding,

La Jolla Cove, 8/7/19: 4 species of storm-petrel

Stan Walens
 

In addition to my usual 2+ hours at the Cove nearly every morning, I usually go back for another 90 or so minutes in the afternoon.

The birds every morning have been pretty consistent in numbers and species, and in being mostly far offshore.
Others have reported those numbers, so I won’t reiterate them.

This morning’s seawatch turned up the usual stuff.
Yesterday, Mel Senac and I saw an Ashy Storm-Petrel working the kelp edge to the WNW of my bench. [Use your compass; the Cove is not aligned due north from my bench.]
This morning Paul Lehman and I had one in the same area; he later saw [another?] one further out.

Otherwise, it’s one Black Storm-Petrel after another.
Mostly in the 35-50 range this past week.

Also present this morning, the usual 500 or so Black-vented Shearwaters. Today, a small influx of Pink-footed Shearwaters, somewhere between 4–6.
No boobies.

This afternoon from 2:00–4:15 was really dull. Maybe 35 Black-vented Shearwaters total. No other tubenoses or boobies except the same 25+ Black Storm-Petrels weaving back and forth.

But at 4:10 a large pod of common dolphins came from the open part of the canyon to the NW into the close part of the canyon to the NNE of my bench, bringing with them an influx of other storm-petrels.
In addition to another 20 or so Black Storm-Petrels, there were 3 Leachs’ Storm-Petrels and 2 Least Storm-Petrels mixed in.
These are the first Least Storm-Petrels I’ve seen in maybe 3 months, since I saw 1 soon after the unprecedented influx of Black Storm-Petrels into the Cove began.


On a non-birding but essential topic:
As I predicted, the use of 8 porta-potties to serve the crowds at the Cove is a disaster.
They need 3 times that number and to have them emptied every day.
The only functioning toilet facilities are at Children’s Pool, and they are overburdened now, too.
So do not come to the Cove [for the next 3 years] if you think you might need to use a bathroom.

[LACoBirds] White-eye confusion

Justyn Stahl
 

See below for an email from Kimball Garrett regarding updated eBird treatment of white-eyes in Southern California. In short, records of Japanese White-eye in San Diego (mainly the Encinitas area) have been converted to Swinhoe's White-eye, and will be replaced as such on the filter.

Birders,

The [ongoing] taxonomic update in eBird includes some changes not already familiar to many birders (i.e., not adopted by the AOS, whose annual published updates are familiar to most of you).

Especially relevant to Los Angeles, Orange and San Diego counties [feel free to cross post to those listserves] is the new treatment of white-eyes.  eBird/Clements has adopted the conclusions of Lim et al ["Molecular evidence suggests radical revision of species limits in the great speciator white-eye genus Zosterops," Journal of Ornithology 160:1-16, 2019].  The upshot is:

"Our" birds are considered to be Swinhoe's White-eyes, Zosterops simplex.  I hasten to add that this is VERY TENTATIVE -- we still have no firm proof that this is what the southern California birds are, but it is the current best guess.  This taxon was formerly considered a mainland China and se. Asia subspecies group of the Japanese White-eye, Z. japonicus, but has now been split from that species.  eBird has automatically changed all previous entries for "Japanese White-eye" in southern California to Swinhoe's White-eye.

"Japanese White-eye" has gone away.  Zosterops japonicus is now called the "Warbling White-eye" and includes populations from the Japanese archipelago (mostly nominate japonicus, also introduced to and abundant in the Hawaiian Islands) as well as various subspecies in the Philippines and Indonesia which were formerly considered the Mountain White-eye, Z. montanus (which has also gone away).  So if you were used to entering white-eyes from southern California into eBird as "Japanese White-eye," this is no longer the correct option (and, in fact is not even an incorrect option as the name Japanese White-eye has been retired in favor of Warbling White-eye).

Also, the "Oriental White-eye," Z. palpebrosus, is on a few old eBird lists since it was established in the San Diego area back in the 1970s to early 1980s.  Because of the recent taxonomic revisions, that species is now largely restricted to the Indian subcontinent and has been rechristened "Indian White-eye."  

So my recommendation is to enter white-eyes here as Swinhoe's (Z. simplex) in your eBird lists, although you certainly still have the more conservative option of "white-eye, sp. (Zosterops, sp.). "  L. A. County [and San Diego] filters have been set at "0" for white-eyes -- hence, all entries are flagged and you need to "Show Rare Species" or use the "Add Species" function to find them on the checklist. We've done this to make certain there is a clear pattern of establishment before we stop requiring documentation.  We emphasize that there is still little indication of colonization of the inland portion of the L. A. Basin and the valleys [or the majority of San Diego], so reports from those area should always include documentation.

White-eye ID, and some other bird news

lehman.paul@verizon.net
 

Also, FWIW, some Chestnut-flanked White-eyes have very faint chestnut/buff flanks. Telling Oriental (now Indian) from Japanese/Chinese (now Swinhoe's) White-eyes requires good, careful looks, and probably many birders did not do so in the past. The yellow vent stripe present in Oriental/Indian but lacking in Japanese/Chinese/Swinhoe's is often a character that is difficult to assess in the field without very good views.

In other news, there was a Lesser Yellowlegs this morning, Aug 9th, at the saltworks, but it was last seen flying off well to the south. Yesterday morning, there was a Belted Kingfisher I first picked up a half mile offshore, but which flew straight to shore, at La Jolla. Presumably a migrant.

La Jolla road closure

Justyn Stahl
 

Please be advised: The City today will begin an emergency construction project to stabilize a zone of weakness in a local sea cave located underneath Coast Blvd. Sections of Cave St. and Coast Blvd. will be closed temporarily to all traffic for about 6 weeks.”


That would appear to close all the parking from the Cave Store to La Jolla Cove.

Justyn Stahl

La Jolla road access and current Birds

lehman.paul@verizon.net
 

While the steep one-way road down the hill at La Jolla past the Cave Store is indeed now closed, all one needs to do is continue past that on Prospect to Girard and then turn right and go down the little hill and you come into La Jolla Cove just at the east end of the regular parking stretch, the same road you normally leave on, so all the parking that one normally uses for La Jolla Cove is still currently accessible and usable.

So far this morning (Saturday) I have had an ashy storm-petrel present off and on for a half hour and one southbound Common Murre.

Yellow-crowned Night Herons at Batiquitos Lagoon

Paula Theobald
 

Three Yellow-crowned Night Herons, two adults and a juvenile, were observed this morning at the lagoon at two locations.  All three were seen at the same time spread out along the reedy shoreline along the I5, south of the I5 bridge. One adult and the juvenile flew across the lagoon and into a small tree/large bush on the trail that leads from the Gabbiano Lane parking area towards the I5. We didn’t see any of the three under the bridge as others have observed.

REMINDER: Tuesday, 13 August, SDFO meeting - - one week early this month!

Barbara
 

Our meeting this month will be held on Tuesday, August 13, at 6:00 PM, in the Hoffman Room of the San Diego Foundation Building, 2508 Historic Decatur Rd. NOTE THAT THIS IS A WEEK EARLIER THAN USUAL because of room availability. 

Our program this month features Susan Farabaugh, Ph.D., Associate Director, Recovery Ecology, San Diego Zoo Institute for Conservation Research. She will present “Of Aga and ‘Alalā—Conserving Endangered Corvids on Pacific Islands”. San Diego Zoo Global’s Hawaiian Endangered Bird Conservation Program (HEBCP) has been active in conservation breeding of critically endangered Hawaiian birds since the mid-1990’s.  

Susan Farabaugh grew up in Southern California and was first introduced to the fascination of birds at Occidental College under Dr. Luis Baptista. She obtained her PhD from the University of Maryland College Park studying dueting behavior of tropical Thryothorus wrens in Panama and Venezuela. As a postdoc, she worked on song sharing in group-living Australian Magpies in New Zealand and Australia. It is worth noting that on the way to New Zealand, she stopped in Hawaii to visit a friend who had recently been hired to manage the small breeding colony of ‘Alala, then located at Pohakuloa on the slopes of Mauna Kea. While analyzing magpie song back in Maryland, she became involved in research of perception and neurobiology of vocal learning in birds. This led to a postdoc on neural control of learned vocalization in parrots and songbirds at Auckland University in New Zealand. On her return to the USA in 1997, she took what she thought was a short-term job with the San Diego Zoo assisting the HEBCP with behavioral monitoring of breeding of ‘Alala. This proved to be a major change of direction, and she joined the permanent effort of conservation breeding of the San Clemente Loggerhead Shrike in 1999 and has been managing the shrike program since 2006. In 2015, she became an Associate Director and now manages both shrikes and the HEBCP. 

Next month’s meeting is on Tuesday, September 17. Charlene Glacy will tell us what it is like to count albatrosses on Midway Island.

Miscellanea

lehman.paul@verizon.net
 

Today, Monday, there was a fall arrival Blue-wing Teal with several cinnamon teal at the main Dairy Mart pond, where also a couple least bitterns, and a coastal arrival Prairie Falcon bordering the salt works. The family group of nesting burrowing owls continues well eastsoutheast of the north end of 13th Street. Similar to the last couple years in August, multiple barn owls have been hunting in daylight over the Tijuana River channel weeds visible from the Dairy Mart Road bridge during overcast mornings.

Saturday morning at La Jolla, in addition to the previously reported ashy storm-petrel and common murre, there was a good count for August of 2000 Black-vented shearwaters and the usual 50 or 60 black storm-petrels, plus one brown booby.

Laguna - fall arrivals

Nancy Christensen
 

This morning (Monday Aug 12) I visited the Agua Dulce area in the Laguna Mountains. Hummingbirds were numerous, with Rufous/Allens being the most common type. All were hatch year young birds. I assume they were probably Rufous, but cannot absolutely confirm that. Warblers were present in fair numbers for the mountains: Hermits, Wilson’s, Black-throated Grays, Orange-crowns  and MacGillivray’s were all seen.

 

The Twilight Zone portion of the walk involved a SORA perched in a sapling Black Oak tree about ½ mile from the nearest water. When I saw this bird, it was not immediately obvious to me what it was because it was blocked by foliage. Eventually I got looks at enough parts that I could ID it, and get some record photos. It was about 3 feet off the ground, awkwardly walking along the branch picking something off the leaves. This totally unexpected encounter teaches me that birds don’t always do what you think they should do!

Off-topic: ordering Steve Howell's new Oceanic Birds of the World at a discount

Stan Walens
 

I am about to order a copy of Steve Howell’s new book, _Oceanic Birds of the World: A Photo Guide_, published by Princeton University Press.
Since my first book was published by PUP, I can order their books at a discount.

As I’ve done before with PUP books, I am willing to order copies for others in the SD birding community at that discount.
The book lists at $35 + tax. Amazon is selling it at $28.50 + tax.

My total cost is a little bit shy of $25/copy, including tax and shipping [exact amount depends on how many copies I order, but that’s the ballpark figure].

If you’re interested, contact me off-list.
I’d like to place the order in the next day or two, since I’m eager to start reading it.

Re: Laguna - fall arrivals

Nancy Christensen
 

A correction – I believe the two birds I listed as Nashville Warblers were actually hatch year female-type MacGillivray’s. Both had complete gray collars, just paler under chin, not split collars as a Nashville would have. Sorry!

Migrant Wilson's Warbler in Vista

Terence Brashear
 

Was pleasantly surprised to see an adult Wilson's Warbler bathing on the shrubbery that had been recently watered late today.  First one I have seen in the area so assuming it is a migrant.

Not earth-shattering, but a nice sighting.

Sunday Aug. 18, 2019 Buena Vista Audubon and Grande pelagic

David Povey
 

Just a reminder that the BVAS and Grande 12 hr. trip is this Sunday. 
Parking will be very tight.
Fishing is exceptionally good right now, several construction projects have cut into the local street parking, and to top it all off the America's Finest City Half Marathon will close off portions of Scott St., and North Harbor Dr. 
I highly recommend an early arrival to find parking, and check in at the H&M Landing office by 
6 a.m. the marathon starts at 6:15 a.m. out at Cabrillo. N.M.
I do plan to get the boat away from the dock on time  !
See you there,

Hornblower Aug 16 & La Jolla Cove, Aug 17: Black-vented shearwaters and a Franklin's gull

Stan Walens
 

Was out on the Hornblower yesterday. It was a mono-species day. Somewhere between 2000-2500 black-vented shearwaters. Hard to count because the boat turns in circles as it follows the one whale it finds. But one raft of black-vents was over 1000 birds. There were so many shearwaters circling the boat that even the Whalers were astonished. No other species of shearwater, no storm-petrels, no alcids [even though conditions were great for seeing them if there’d been any].

Almost the same today at the Cove except even more black-vents. I counted 120/minute streaming north into the canyon for close to an hour.
Probably somewhere around 5000 total, possibly more.
No other tubenoses. No boobies. No alcids.
Hundreds and hundreds of common dolphins everywhere, with swarms of shearwaters following them.

A first-winter Franklin’s gull was roosting on the rocks beneath my bench when I got there, but was almost immediately chased off by tourists trying to see how close they could get to the sea lions.
The gull flew deeper into the Cove and may have landed on the cliffs or headed to the beach at La Jolla Shores, but I was distracted by the multitudes of shearwaters and hoping for something besides a black-vent, and didn’t feel like chasing it.

Lesser Yellowlegs, Reddish Egret, N. Red Bishop

Justyn Stahl
 

The highlights from various locations in the TRV and the San Diego River today, 17 August included:

REDDISH EGRET continuing at J St.

A male NORTHERN RED BISHOP (ooh ahh) was at the mostly overgrown “stick pond” at Dairy Mart, where perhaps more notable was an adult LEAST TERN circling.

The sod farm actually had green irrigated sod but it was totally devoid of any birds.

An adult COMMON TERN was at the Robb Field stretch of the San Diego River, and up stream just east of the 2nd bridge (Old Sea World Drive), were three LESSER YELLOWLEGS.
