Black Rock Campground Birding, May 2, 2026

May 16, 2026

[By Jean Garrett, additional comments by Chuck Almdale , photos by Chuck Almdale & Ray Juncosa]

Greater Roadrunner (Ray Juncosa 5/2/26)
One of the things “they” say is “Any day with a roadrunner in it is a good day.”

We arrived at 3:00 PM to a quiet scene at the campground. Again, a Say’s Phoebe family had their nest by the door of the nature preserve station. It must be a safe place!

Nearby, a Bewick’s Wren led us to his nest where we could hear the young ones chirping. A California Thrasher perched conveniently for us while we were looking at a male & female Ladderback Woodpecker accompanied by the sound of Black-throated Sparrows.

 Little did we know that we would be seeing the Black-throated sparrows everywhere we went in the campground.

Although Black-throated Sparrows are highly-adapted to arid deserts, they will drink water when they can get it. But during the long, dry desert summers they can survive for long periods without it, getting necessary moisture from their diet of insects, succulent vegetation, and seeds.

Another sound we could hear (besides House Finches) was the Gambel’s Quail whose call sounds so close to the California Quail’s “chi-ca-go”. But after settling the debate on the sound, the sentinel Gambel’s Quail finally showed itself. 

The very best sighting for the day was a Roadrunner (photo at the top) standing on a rock and letting us see him for at least five minutes. All that was missing was to hear him sing. 

California Scrub Jay (Ray Juncosa 5/2/26)

Scrub Jays bounded through the Joshua trees and Eurasian Collared-Doves gave background songs. 

Unlike the introduced Eurasian Collared Dove, the White-winged Dove is a native to southeastern California deserts. It seemed to be more common this year than in prior years, and we had them not only in the town of Yucca Valley, but also at Black Rock and at the Morongo Valley Reserve. (Ray Juncosa 5/2/26)

Looking up at the sky offered a glimpse of a Turkey Vulture and a Red-tailed Hawk. We finished our list with an American Kestrel and a couple of Cactus Wren nests but no bird. Judging by the lack of flowers and the maturity of the seed pods on the Joshua Trees, it seemed like spring had come early.

Black Rock campground is a great place to visit if you want to see what Joshua Tree National Park looks like, but are too thrifty or pinched for time to drive into the main park. It’s part of the National Park, but you don’t have to pay admission, you can park by the camp HQ and walk anywhere you want. You can camp (now $35!, reservation needed), it’s only a few miles to the town of Yucca Valley, and the habitat is much the same as the main park with lots of cactus you can admire at an appropriate distance. Many of the cholla cacti harbor old nests of Cactus Wrens. We stayed at a town motel, and can recommend Las Palmas Mexican Cuisine for dinner.

We then drove through the campground, past the rangers’ offices and left up the dirt road that leads to the Hi-View Trailhead, perhaps a mile up-canyon. As you can see on the map below, trails branch out in all directions. Wear appropriate shoes, or better, thick soled boots. Cholla cactus thorns are long and strong, very tough to pull out of your boot or ankle and they hide on the ground when the cactus joint falls off.

At the parking lot we found a large lizard sunning itself on a fence post. The dark mark on the neck identified it as a Desert Spiny Lizard, Sceloporus magister.

Desert Spiny Lizard, Sceloporus magister has a really long tail. (Chuck Almdale 5/2/26)

The Peterson Field Guide to Western Reptiles & Amphibians says this lizard is 3.5-5.5″ long, from snout to the vent by the rear legs. As the tail is definitely longer than the body, this makes it about a foot long.

Note the blue-green throat.

The altitude here is slightly higher than in the campground and the trail we had just walked, and there were more short bushy juniper trees than there had been down slope.

Black Rock side canyon landscape (Chuck Almdale 5/2/26)

The trees became increasingly more numerous as we walked upslope. We hoped for Pinyon Jays to pass overhead as this is the edge of their Pinyon-Juniper habitat, and we often see them in the general Black Rock vicinity. Once, in the early morning, about 100 of them invaded the campground, perching on yuccas, joshua trees, poles, wires and picnic tables everywhere. But no such luck today.

Our local Woodpecker hybrid: Ladderbacked x Nuttall’s

Ladderbacked Woodpeckers are resident in the arid deserts from SE California east to SE Colorado, West Oklahoma, the western half of Texas and nearly all of Mexico. Nuttall’s Woodpecker is the western damp riparian habitat version, resident from northern California to northern Baja California, from the ocean to the montaine forest of the Sierras and Cascades. These two are very similar in appearance, and for at least 20 years if not far longer, their hybridizing has been noted, particularly in this area near Joshua Tree National Park, and especially at Morongo Valley Preserve, which we visited the following day. Here all sorts of hybridization mixtures have appeared, as backcrosses have created what can be called a “wobbly (or ill-formed) spectrum” of variation, although there’s probably an official scientific term for what appears, when “good” types of Nuttall’s or Ladderbacked breed with one another, then with various hybrid offspring, and hybrids breed with one another until all sorts of genetic mixtures result in a mélange of plumage appearances.

I believe this bird is the first hybrid I’ve seen outside of the Morongo Valley Reserve and next-door-neighbor Covington Park, and it was on a pole near the Black Rock Campground HQ building. The pole wasn’t performing any function, but looked as if it once had a crossbar or something else placed on it. The hole (see photo below) may have held a long bolt to keep the crossbar in place.

The face pattern of this individual looks much like that of the juvenile Nuttall’s with the large white streak beginning over the eye and widening out as it descends onto the shoulder. But there is no red forecrown which juvenile Nuttall’s possess. The black face pattern also connects onto the black shoulder, as with Nuttall’s. The nasal feathers are very light brownish. Ladderbacked and female Nuttall’s can have brownish nasal feathers (or tuft), but the pattern here looks more like Ladderbacked..

Woodpecker hybrid Ladderbacked X Nuttall’s (Ray Juncosa 5/2/26)

The black area at the top of the shoulder is not only narrow, as with Ladderbacked, but is irregular, possibly a result of gene mixture. The amount of black here looks almost intermediate between the two species. The pale areas on face and front are quite white, as with Nuttall’s. except for the previously mentioned nasal tuft, part of the neck and part of the upper breast, which have a brownish wash like that of the Ladderbacked. The back and wing streaks/spots seem more like Ladderbacked.

Woodpecker hybrid Ladderbacked X Nuttall’s (Ray Juncosa 5/2/26)

In the photo below, note the slight brownish wash, most noticeable above the bill, lighter on upper breast and very light on the neck. The black face pattern connects to the shoulder, and the black bar at the top of the striped back is moderately thin and irregular.

Woodpecker hybrid Ladderbacked X Nuttall’s (Ray Juncosa 5/2/26)

It seems that the results of this hybridization are moving out beyond their Morongo Valley Preserve homeland. Although I do conclude that this is a hybrid, we’ve previously seen more convincing hybrids at the preserve than this one.

Woodpecker hybrid Ladderbacked x Nuttall’s Woodpecker (Chuck Almdale 5/2/26)

The primary definition of species is the Biological Species Concept, which defines a species as a group of organisms that can successfully interbreed in nature and produce fertile offspring. Ladderbacked and Nuttall’s Woodpeckers are doing this, and the blended plumages of their fertile offspring are carrying the evidence. These species will probably be lumped in the not-too-distant future.

Unfortunately we didn’t post any reports or keep a checklist for our trips between 2015 and 2026. We had many noticeable misses on this trip, particularly flycatchers, Cactus and other wrens, sparrows, Scott’s Oriole and warblers. Again, as was noted with the absence of wildflowers and the emptiness of Cactus Wren nests, perhaps spring arrived early here this year.

Evolution in Urban Dark-eyed Juncos, with Dr. Pamela Yeh and her graduate students Mars Walters, Sierra Glassman, Prasheetha Karthikeyan, & Joey Di Liberto

The Yeh Lab is excited to be giving a talk on evolution in urban dark-eyed juncos (Junco hyemalis). Dr. Pamela Yeh, Associate Professor at UCLA, will start by discussing some of the history of the lab’s work on the juncos and providing an overview of the work being done in her lab. PhD student Mars Walters will talk about a long-term behavioral shift in UCLA’s dark-eyed juncos induced by the COVID-19 lockdown. PhD student Sierra Glassman will talk about her in-progress research on urban genomic evolution of juncos across California. MS student Prasheetha Karthikeyan will discuss her ongoing research on the flocking behavior of urban dark eyed juncos on the UCLA campus during their nonbreeding season. Lastly, another PhD student, Joey Di Liberto, will present new research on how female juncos adjust the volume of their eggs across their nests as well as over the breeding season; and what this means for how birds manage reproductive investment in changing conditions.



Dr. Pamela Yeh

Dr. Pamela Yeh is an Associate Professor in the Department of Ecology and Evolutionary Biology at UCLA.  She studies how human activities affect the evolution of species, focusing on the evolution of birds in urban environments and the evolution of drug­ resistant bacteria in urban and agricultural areas. She is also interested in the role biology plays in public health, and how biological data and insights can both inform public health research as well as public health policy.She received her PhD in Evolutionary Biology from UC San Diego and has conducted post-­doctoral work in the Center for Genomics Research and the Systems Biology Department, both at Harvard University. She has been at UCLA since 2013. Dr. Yeh is also an External Faculty at Santa Fe Institute.


Mars Walters is a Ph.D. student in the Yeh Lab at UCLA. They are studying the evolutionary mechanisms shaping urban phenotypes in the dark-eyed junco, from behavior to genomics. They earned an MS in from the Yeh Lab in 2022 and a BS from the University of Georgia in 2013. Mars has worked as a field ornithologist and researcher for USGS, the Audubon Society, and the Smithsonian Institute in diverse ecosystems across the United States.


Sierra Glassman is a National Science Foundation Graduate Research Fellow and a second-year PhD student in the UCLA Ecology & Evolutionary Biology program in Dr. Pamela Yeh’s Lab. She is interested in birds’ responses to human-induced environmental change. She researches the morphology, behavior and genomics of urban adaptation in Dark-eyed Juncos. She graduated from UC Berkeley with a BA in Integrative Biology in 2024, where she researched the vocal and foraging behavior of Anna’s Hummingbirds. She also has worked as an assistant for the UC Berkeley Schell Lab, where she aided urban mammal cognition and biodiversity research.


Prasheetha Karthikeyan is a first year M.S. student in the Yeh Lab, studying the social and antipredator behavior of dark-eyed juncos. She earned her B.S. in Environmental Science from UCLA, where she discovered a passion for urban ecology and joined the Yeh Lab initially as an undergraduate research assistant During this time, she also worked in positions focused on conserving Threatened and Endangered Species, with an emphasis on wildlife impacted by urbanization.


Joey Di Liberto is a graduate student in the Yeh Lab at UCLA. Using the model system of Dark-eyed Juncos across the state of California, he is examining how animals may be adapting to urban pressures across individuals, populations, and subspecies levels. Prior to beginning work at UCLA, Joey obtained his BS from UC San Diego, and his MS at the College of William and Mary and throughout has worked to study behavioral ecology and conservation in a variety of avian species.

Franklin Canyon Spring Bird Walk reminder: 8:30am, Sat. May 9, 2026

May 7, 2026
Franklin Canyon park in the fall.

[By Lu Plauzoles, posted by Chuck Almdale]

We plan to meet at 8:30AM at the parking lot below the Sooky Goldman Nature Center. (restrooms there) I believe most navigation systems will recognize that site.

I will try to scout the area two days before the walk to ascertain the correct route and post any changes on the blog. However, expect to be taking N. Beverly Drive north past the Beverly Hills Hotel from Sunset Blvd. Left at the fork (tri-light) with Coldwater Canyon and then the very narrow Franklin Canyon Drive.

A line of Mallards and Wigeons.

The north entrance from Mulholland Drive and the Tree People site IS STILL CLOSED because of road damage from rainstorms four years ago.

From Santa Monica, please allow 35-40 minutes travel due to early-morning traffic.

Please exercise extreme caution in respecting stop signs on the park road. Intersections are camera-controlled and since this is National Park Service land, photo-enforcement is serious and enforceable. (Like, $300-worth!) Do not expect cellphone reception in this narrow canyon.

We expect to walk down the length of the canyon and come back to the parking structure via the same route. Total approximately 1.75 miles walking. Approximately 2 hours with good looks at lingering warblers and wrens in classic southern California riparian/chaparral habitat, as well as the occasional waterfowl in the reservoir. Let’s see if the Common rAvens still own the real estate. The prize bird if we can spot one is the Hutton’s Vireo!

I read this on The Guardian. A rational solution to the pollution of the water near Santa Monica Pier? It certainly doesn’t sound very expensive.

Lasers, hawks and even guns haven’t solved the UK’s pigeon problem. There is a better way

The Guardian: by Sydney Lobe, 4 May, 2026
The author has been spending time with the National Pigeon Advocacy Association (NPAA) and its president, Sue Joyce (AKA Sue the Pigeon Lady). Joyce has a vision of an avian utopia where the pigeon “problem” is solved for good.

Birds large & small: Malibu Lagoon: 26 April 2026

May 1, 2026

Most of our shorebirds have flown to points north. But the Elegant Terns have returned in force from the Sea of Cortez. An preliminary count shortly after I arrived at 8:15 am yielded about 150 terns and as many gulls. By the time I left three hours later, the gulls remained the same but the terns had exploded to almost 800 birds.

The tide was dropping from a high of +4.32 ft. at 6:24am to the low of +0.00 ft. at 1:06pm, so there was lots of damp mud and damp sand everywhere. In one of the slowly draining channels was a single female Pintail, probably the same lone female we saw last month in the same channel at the very same spot. We don’t get many Pintail: before last month the last Pintail was a single bird in October 2022. In fact we’ve had double-digit Pintail only three times: twice (12 and 10) in 1979, and 10 in January 2012. The wildlife refuges north of Sacramento during the winter have a lot more than Malibu Lagoon ever will.

A handful of Killdeer were out and about. They have nested in the sandy soil surrounding the lagoon since at least the 1990s when I recorded a nest with eggs for the L.A. County Breeding Bird Atlas. So of course we’d like to see one for the new California Bird Atlas. But we didn’t.

People often ask about the odd name, Killdeer. These birds have nothing against deer. It’s one of those onomatopoetic names, as the call it makes when alarmed or in flight sounded to so some ears – not mine in particular – as “kill-deer” or “kill-dee” or at least it did back in the 1730s. It has also been called the noisy plover or chattering plover.

Killdeer (Chris Tosdevin 4/26/26)

Brown Pelicans have an extended nesting season. West Anacapa Island and Santa Barbara Island are reportedly their only breeding location in the U.S.; most breed in Mexico. They have an “extended breeding season running from January to October. This is a bit misleading though, as most begin nesting in March or April, they incubate their 2-3 eggs for 4 weeks, the young begin to fly 5 weeks later, and they become independent of their parents not long thereafter. So each individual pair spend about 9 weeks nesting, but when they begin nesting is quite spread out. Malibu Lagoon is located 41 miles from both their SoCal breeding locations, and it is popular with them year-round. They are at the lagoon on all our trips in numbers ranging from a handful to 1500 birds. The last time they weren’t here was in July 2005; before that you have to go back to October 1983, when they were still having problems with DDT weakening their egg shells.

Western Grebes are still with us. There may still be a few with us in May, but I wouldn’t bet on it. Their presents peaks October to March. We had two Clark’s Grebes twice this winter, which is almost a record as in the winter of 2017-18 we had five. We’ve never had more than two at a time. In SoCal they prefer the fresh water of our reservoirs.

Western Sandpipers

Western Sandpiper presence at the lagoon is erratic. They’re mostly gone by late October and begin returning in March, disappearing again for May-June, returning again in July. The highest numbers are usually in March and April. In fact they can be seen in any month, but there might be only one or two of them. This visit started with one bird, which grew to nine, and just before I left another twenty flew in. Here’s a good look at Western Sandpipers in alternate (breeding) plumage, although some of them might develop a few more black spots or rusty tinges.

The 10-year comparison summaries created during the Lagoon Reconfiguration Project period, remain available—despite numerous complaints—on our Lagoon Project Bird Census Page. Very briefly summarized, the results unexpectedly indicate that avian species diversification and numbers improved slightly during the restoration period June’12-June’14.

Many thanks to Femi Faminu, Chris Lord, Armando Martinez, Emily Roth, Chris Tosdevin and others for contributions made to this month’s census counts.

The species list below was re-sequenced as of 12/31/25 to agree with the eBird sequence. If part of the right side of the chart below is hidden, there’s a slider button inconveniently located at the bottom end of the list. The numbers 1-9 left of the species names are keyed to the nine categories of birds at the bottom. Updated lagoon bird check lists can be downloaded here.
