Re: FRNC Kentucky warbler

Carl Ebeling

I was there for about an hour starting about 7:15 am, and did not see or hear the Kentucky Warbler (the handful of birders already there when I arrived had not seen or heard it, either.).   I went off to check a few other nearby potential locations (also without luck), and afterwards (about 45 minutes later) went back to see if the KEWA had surfaced in the meantime.  It had not.

Indigo Bunting found Sunday AM Paso Picacho

Roger Uzun

I was able to find the Indigo Bunting at Paso Picacho Campground near Lake Cuyamaca.  The bird was never visible from the bathroom/shower area.  You could only see it from the footbridge as it was in a pine tree just past the footbridge that was obscured from the bathroom area.  The bird never came close to where we were, I only got fairly distant looks.

I arrived around 8 AM and did not see the bird until around 9 or 9:30.  Another Birder found it in the bushes under the Pine tree and it went from the bushes up to a mostly dead pine tree.  The pine tree it went up in was dead in the bottom/middle but had some green needles at about the top 10% of the tree.  If you are on the footbridge and looking at the bathrooms the pine tree is to your left.

I did get about 10 secs of video of the bird singing if that helps anyone.

Did not see anything else unusual.  ebird list here -

Here are some photos of the birds at Paso Picacho and some around the house before I left.  I had a Phainopepla pair at my home near Iron Mountain in Poway, first time I've seen those here.

I went to SE Arizona in early May and made a short video of the birds I saw there, including Elegant Trogon and Flame-Colored Tanager.  You can see it here -

Re: The putative Indigo Bunting at Paso Picacho

James Pike

Hi Chris,

Thanks for the tip about reading page 26 regarding hybrids in Pyle (1997). He does warn about the possibility of "pure individuals showing.......anomalous plumage coloration, which may coincidentally cause them to resemble a suspected hybrid with another species." I don't believe anyone is suggesting that might not be the case with this interesting individual, nor is anyone bandying about terms such as"incontrovertible proof" in regard to its provenance. I still believe it is a hybrid, and my impression is that you disagree. Cool. Spirited exchanges can be fun and edifying, right up until the point when that no longer is the case. I think we've reached that point. As for the photos I looked through online, I concluded that the vast majority of those male Indigos that look similar to this bird are immatures, which this bird is not. Thus, what is the likeliest explanation for the aberrant appearance of this bird: that it  is a hybrid, or that it is an oddball? In my opinion, the odds favor it being a hybrid, but it is possible that I'm wrong. 

regards, Jim

Pyle's 1-3/4 quarter pages covering Indigo Bunting for 1997 certainly doesn't benefit from the data gleaned out of the the last 21 years ( He mentions the need of more study of the species in that brief). While you have your Pyle out, consult page 26 regarding Hybrids. As for the presence of a white (or white-ish) on the vent tract area designating the bird as a Hybrid, what is your basis for that "...incontrovertible proof" ?? Specimens, photographs (any one of the "hundreds" stand out for you?), sonograms to reference would be nice. I'd rather see reference to photos of a confirmed hybrid that remotely resembles this bird IN THE FIELD than an obscure commentary about a Blue-winged warbler rejected by the CRBC. Anything other than speculation would be more relevant to this discussion rather than commentary about why the birds is not a first breeding season/Summer/ AHY bird. It would seem the burden of proof in this case falls on why IS it a hybrid? And that extends beyond a white vent patch, "extensive" or otherwise.
"So for me, the presence of such extensive a white belly on the Paso Picacho bird is incontrovertible proof of Lazuli Bunting ancestry and puts pure Indigo Bunting hors de combat." That doesn't really cut it. For me.
Xeno-Canto offers many variations of Indigo bunting songs to consult.
At the very least, let's discuss why with references rather than anecdotes.

Sunday June 10, 2018 pelagic

David Povey

The Sunday  June 10th. Buena Vista Audubon pelagic had a two white bodied Boobies. An adult Nazca Booby was well seen

close in on the water and in the air off Coronado/Silver strand. This bird had a bright orangey bill. Photos of this bird showed

the that the bird was banded and we could read a partial number. ( Oregon rescue bird ? ).

A sub/near adult Masked Booby few over the boat mid San Diego Trough ( south end ). This bird had a little dark shading to

the head and some scattered dark feathers in the upper wing coverts. Otherwise adult plumage. The bill color on this bird a

dull yellowish .

A Townsend's Storm-Petrel was seen and photo'd with a small group of "Chapman's" Leach's Storm-Petrels mid San Diego

Trough ( north end ). Based on smaller size, stubbier wings and bright white upper rump patch.

We also had a very distant mystery shearwater on the Thirty Mile Bank. Once we looked at photos on a bigger screen, and

no longer bouncing around the ocean We now believe that bird was  a Pink-footed Shearwater.

FRNC – "Western" Palm Warbler, June 11, 2018

Gary Nunn

I made a quick circuit of a few favorite spots at Fort Rosecrans National Cemetery this morning.

I found a spring migrant "Western" Palm Warbler feeding along the east fence line south of "The Wall" and eucalyptus trees.  Checking through eBird reports I could find only one other report of this species in California for May-June 2018 from Hi Sahara Oasis in San Bernadino County.

I assume that sooner or later photographers who were on the trip on June 10 will be posting their photos to eBird, etc.

But I am extremely eager to see photos of the distant shearwater that David said was concluded to be a pink-footed shearwater. If you have photos of that bird, could you please email them to me, or let me know when they’ve been uploaded to eBird or whatever?

Mountain chickadees in lowlands?

Joseph Parvin

Recently I have noticed some mountain chickadees in some Japanese Black Pines near my home in Escondido. I’ve heard of chickadees coming down to the lowlands during winter, but never during the summer. Any thoughts?

Re: Mountain chickadees in lowlands?

Greg Gillson

Mountain Chickadees are resident in small numbers in residential pines throughout Escondido, San Marcos, Vista.

Best eBird hotspot location for these lowland birds is probably Oak Hill Memorial Park in Escondido.

Post-breeding dispersal of young. Sometimes they overshoot typical habitat. Happens in all species.


Chickadee breeding was confirmed in atlas square G-8, more toward San Marcos than Escondido. A dispersant from there wouldn’t be much of a stretch.

Pt. La Jolla – distant black-and-white booby, June 14, 2018

Gary Nunn

I made a seawatch this morning from Pt. La Jolla just near the usual Bridge Club location.

A large number of Black-vented Shearwater there with several rafts of sitting birds and a large congregation over Common Dolphin about 1/2 mile north of the point.  I would estimate 3000 Black-vented Shearwater in total with solid line of movement north to south.  Also a handful of Sooty Shearwater investigating the dolphins.

About 8:15am I spotted a very distant white bodied booby flying south to north low over the water.  It banked a few times giving dorsal views and clearly white with black wing tips and trailing edge to wing.  I could not detect the tail color, or the extent of the black trailing edge on the inner wing, or really if it looked dark masked because of the distance.  I am assuming Masked/Nazca Booby given recent reports but honestly so distant I could not discount adult white morph Red-footed Booby.  It got close to some northbound Black-vented Shearwaters and did not seem as large as I expected but again these were very distant viewing conditions.

Anyways, something to continue looking out for locally!

Re: Pt. La Jolla – distant black-and-white booby, June 14, 2018

Stan Walens


Gary’s post reminded me that I wanted to note some minor observations from these past few weeks, when I’ve gone out about 4 mornings and 4 afternoons each week.
I am glad Gary reported 3000 black-vented shearwaters, because that’s about how many I’ve seen every day when I’ve gone out in the morning this past week [stayed home today].
Most eBird reports have had only numbers around 150.
I also find that the large numbers of black-venteds often dissipate or move far offshore by 7:00 or so in the morning. So getting there by 5:30-6:00 is de rigueur, even though it can be overcast and windless.

I’ve also found that the black-venteds are replaced by sooties in the afternoon. Yesterday from 3:00–4:00 pm I had maybe 60 black-venteds and about 750 sooties. There have been major feeding frenzies about 1-1/2 miles offshore; I can see thousands of terns and shearwaters, but they are specks in the distance. Light in the afternoons has been harsh.

Interestingly, this season I have yet to see a single storm-petrel from shore; usually by mid-June, black-storm petrels are working the edges of La Jolla Canyon.

Finally, there have ginormous pods of common dolphins near shore, especially in the early morning. On June 9, perhaps the most exciting day I’ve had in 36 years of birding the Cove, though not because of cetaceans, there were at least 2500 common dolphins in the Cove and offshore of the Point.

Re: The putative Indigo Bunting at Paso Picacho

James Pike

Hi Joe,

Your input is always appreciated. I know that the pool of birders still interested in this topic is rapidly drying up, so I’ll make it quick. I enjoyed the Kroodsma article on hybridization in buntings, but some of the assertions merit comment. For instance, he notes that 48% (76 of 158) of adult male Indigo Buntings (INBU) with “ragged brown margins” on one or more of the “proximal three pairs of secondaries” (ie, tertials) also had white feathers on the abdomen. He then concludes that these phenomena are correlated, and a consequence of a “delayed prenuptial molt,” (ie, prealternate molt, or PA), without benefit of proof. Pyle (1997) confirms that the PA molt is incomplete in adult INBU, with, for example, 1-3 tertials being replaced in 59% of birds, but his guide doesn’t bolster Kroodsma’s claim of a delay or lack of completion of the body molt. In turn, Rohwer (1986) concluded that the “PA molt of adult males (INBU) includes virtually all body feathers in most individuals.” Kroodsma doesn’t state that the white abdominal feathers looked more worn than the adjacent presumably fresher blue feathers of the breast on those 76 specimens. Thus, there isn’t evidence that the white abdominal feathers on some, many, or all 76 of these birds couldn’t have been acquired during PA. Based on Pyle (1997) and Rohwer (1986), that would be more expected. A consequence of Kroodsma’s conclusion that the white abdomens of adult males were due to a “delayed” PA molt is that he disregarded the possibility of these white feathers being associated with the introgression of Lazuli genes. Coincidentally, he also didn’t note the presence of backcrosses during his study.  

In any event, as seen in Eric Kallen’s photos, the tertials of the Paso Picacho bunting are black with blue margins and the bird best fits the 2% (2 of 90) of specimens examined by Kroodsma that possessed both relatively fresh tertials and white abdominal feathers. Apart from two dull tiny frayed feathers on the center of the breast, I don’t see evidence of a “delayed prenuptial molt” of the body, but perhaps someone with more experience can.

best regards, 

Jim Pike

I would not place too much weight on the song.  Individuals of both species

Origin & age of banded Nazca Booby in San Diego County waters June 10, 2018

Gary Nunn

On the last San Diego Pelagics trip this past Sunday June 10, 2018 we had the good fortune to find a subadult NAZCA BOOBY sitting on the water about 8:20am.  Per GPS readings the exact location 5.5NM west of Imperial Beach and 1.1NM from Mexican waters to our south.  The booby was spotted just as we motored up very close to it, maybe somehow it was hidden behind a swell, and we immediately stopped the boat and got very close looks at the bird.  The bird was so close in fact that when it took off flying, luckily towards us and along the starboard side in front of assembled photographers, from the many photos taken a metal band could be clearly seen on the right leg.  You have to marvel at modern camera sensors because images so detailed a partial band number could be read.


The information on the band appeared to show a number or alphanumeric either "734.." or "73A.." visible.  You can see the photos on our eBird checklist here


I checked in with Kimball Garrett about the rehabbed Nazca/Masked Booby that had been released at San Pedro, Los Angeles County on Oct 9, 2015 but should have read his original email to the LACOBIRDS listserv first since this bird banded with USGS metal band on left leg.  The San Diego bird, a subadult evidenced by some dark speckling on the white upperparts, also inconsistent considering age.  Kimball confirmed the band did not match that of the San Pedro released bird with USGS band (with number 1038-26057).


A second photo of the San Diego Nazca Booby then surfaced showing the band even more clearly and with an upper line possibly showing word "ANDER...".  I had a hunch about where the band may have come from and reached out to Professor Dave Anderson at Wake Forest University who has been studying Nazca Booby and other seabirds in the Galapagos for the past 35 years.


Sure enough, Dave confirmed the band originated from his lab and he could trace the partial number (734xx) of this Nazca Booby to an immature banded on Isla Espanola, Galapagos Islands, in the first half of 2017.  He estimates the bird's age at 1 3/4 years old at time of sighting here in San Diego.  He told me they have banded about 25,000 youngsters (Nazca Booby) and this is the 71st report of one of their banded birds but the most northerly by 7 degrees of latitude.  Dave noted that most band returns are of 1-2 year old birds from the Pacific coast of Central America.


The age estimate, 21 months, seems low perhaps.  You can see P7 or P8 growing, at least on the right wing, and this would seem to peg the bird, in 2nd-prebasic primary molt, in a 25–26 month age range using a Masked Booby molt pattern shown in Howell, 2010, Molt in North American Birds.  I looked in Howell et al. 2014, Rare Birds of North America, and it states, under Nazca Booby, pp. 117-119, 2nd-prebasic primary molt starting about 14 months after fledging, i.e. about 18 months of age.  Considering the six or seven visible grown primaries, at about a month apiece, this would get us to 24–25 months.  Maybe the discrepancy can be accounted for with individual variation or the original estimate is a bit lightweight.  I will have to look around for Nazca Booby molt publications to understand the variation and check on this again with Dave Anderson.


I will be submitting these complete details to the CBRC along with photographs showing the band number and plumage details of the booby. A credit due photographers Matthew Binns and Todd McGrath capturing images of the band.


We have three more pelagics out of San Diego planned for 2018.  Details can be found at the website and space is still available but August is filling up fast.  In addition to Nazca Booby last Sunday we also found the much sought-after TOWNSEND’S STORM-PETREL – photos here – our next trip in August a good opportunity for this species.

Pt. La Jolla seawatch – Pigeon Guillemot, Common Murre, June 16, 2018

Gary Nunn

I put in a four hour seawatch 6:30–10:30am this morning June 16, 2018 from Point La Jolla.  Actually I had to move a bit south the last hour or so because park rangers put up their public outreach canopy right next to me obscuring the view.

Hoped for a frigatebird maybe on these south winds but no luck with that.  An adult COMMON MURRE in alternate plumage flying south at 7:55am was too distant for photography.  Not the hoped for puffin but raised my pulse a bit.  I continued the vigil and nearly two hours later spotted a slow moving PIGEON GUILLEMOT going south at 9:50am flying into the stiff breeze.  This bird almost too distant for photography too, on the inside of outer kelp line, but I snapped a few frames anyways which can be seen in the eBird checklist below.  It is guillemot season here and I would say one seen about every 6-8 hours watch effort at the moment.  Sightings random and could be first or last five minutes you are out there though!  This bird my second of the "season" after one here on June 9. 

Also two Whimbrel flying south.

The massive bird congregation was very distant offshore this morning.  Looked to be far out over La Jolla Canyon a couple miles distant.  While watching the distant blurry specks of birds I did see a Humpback Whale go full breech a couple times followed by some impressive tail whacking of the ocean.  Amazing how far this large animal can stick its tail out the water!

Hi Catherine,

This is a juvenile tree swallow, some of which can show a blurry breast-band.
Overall color as well as shape and size of the breast-band are wrong for bank swallow..
Also, note the white patches in the sides of the rump, a mark for tree swallow.

Terrific photos.

*Tonight* SDFO Meeting June 18. Guy McCaskie and "Foundation, Functioning, and Accomplishments of the CBRC"

Justyn Stahl

Reminder: the SDFO meeting is tonight, MONDAY, June 18 at 6pm.


Program: Guy McCaskie presents "Foundation, Functioning, and Accomplishments of the California Bird Records Committee." From Rare Birds of California: " The California Bird Records Committee (hereafter the CBRC or Committee) was established in 1970 to help bridge the gap between scientific ornithology and recreational birding. Operating under the auspices of the California Field Ornithologists (later to become Western Field Ornithologists), it was the first committee formed in the Americas for the purpose of vetting records of vagrant and similarly rare bird species."

The Godfather of California birding, Guy McCaskie is the co-founder of both Western Field Ornithogists, serving as its first president, as well as the CBRC, serving as either a member or a non- voting secretary since its inception in 1970. Guy’s impact on birding in California cannot be overstated. A 1992 article in American Birds (46: 204-213) says it best: “McCaskie raised the status of observation of complex avian events to a highly sophisticated part of the scientific procedure. He discovered serendipitously the large-scale and frequent occurrence of vagrants in California and took the lead in systematically exploiting that boon. He recognized the densifying properties of desert oases and coastal sites...As a result, he found birds where no one before him dreamed of looking and set into motion the gears of change for the whole birding community through his leadership and example. He defined the leading edge for a generation of birding innovators by developing a method of critical field observation that was unique when he started and which, for many, is now the standard.”



Next month’s meeting: Tuesday, July 17, same time, same place. Brian Myers will discuss “Courtship, isolation, and a hybrid zone between Allen's (Selasphorus sasin) and Rufous (Selasphorus rufus) Hummingbird.”
