Birds special–birds returning: Malibu Lagoon, 24 July 2022

August 6, 2022

[By Chuck Almdale]

Boot-toe island in the channel. You need an aerial view to see the boot or the toe. (L. Johnson 7-24-22)

We don’t have “July Gloom” because it doesn’t rhyme, so it’s always “June Gloom” whether it’s March or June or October. For November through February it’s “winter low clouds.” So if the sky looks gray and cloudy in our photos, it’s still “June Gloom.” Remember that. There will be a test.

Snowy Egret, feeling plumish (C. Tosdevin 7/24/22)

The clouds kept temperatures quite pleasant: 70-73°F. I suppose those on the sand, lying, trying to get a nice “healthy glow” as we used to say before our skin cracked and and flaked and fell off, leaving us scarred and saggy — they would prefer that the sun shown in the summer as it is contractually obligated to do, but those of us who know better…well, we know better. They’ll be grateful in 40 years.

The Winter Ramp-Summer Clock, mostly dry, but wet at the far end and the curvy part of the sidewalk was under water. Those seemingly-yellowish rectangles along the left side are the water level markers.

Speaking of things to remember, there is that weird-looking curving sidewalk that is sometimes under water and has numbers along it. It was installed about a decade ago during the 2012-13 reconfiguration of the lagoon. It’s called the “Winter Ramp-Summer Clock.” There’s been a page on our blog [we also have permanent pages, not merely blog postings] for only nine years, devoted entirely to it and detailing the construction process, so it’s understandable that you might have missed it.

It was specifically designed to be “sometimes under water” as it measures the water level in the lagoon. (It’s really tough to measure water level without something being under water at least part of the time.) I don’t know if this piece of civic architecture satisfies a great public need other than giving people something to complain about. “What idiot designed this thing? It’s under water!” I cannot say how many times I’ve heard this. No one notices the colored tile plaques marking water level. That’s partially because the paving and plaques gets covered with slimy muck (aka algae) when the water is high.

The previously wet 8-foot 0.8-inch marker tile. At the time of our visit the sidewalk was wet to the 7-foot 7.8-inch level.

The numbers then become covered with muck, and the muck is ugly and slippery and then no one in their right mind walks down the summer clock sidewalk because sometimes it’s also underwater! So, for what’s it’s worth, that’s what it’s called and that’s what it does. This will not be on the test because although I know it has a name, I can never remember what it is. Despite all the foregoing, I still think it’s kind of cool.

Plovers: Black-bellied, Semipalmated & Western Snowy
(Left+Center: C. Tosdevin 7/24/22, Right: L. Loeher 7/29/22)

That aside, we had a few good birds today. (Of course, all these birds always think they’re good.) Species numbers jumped from our typical low month for the year – June’s 35 species – to a respectable 51 in July (see chart at bottom). Birds were returning from the north: Semipalmated Plover, Marbled Godwit, Ruddy Turnstone, Long-billed Dowitcher, Willet, Glaucous-winged Gull, Forster’s Tern.

Barn Swallow feeding frenzy (C. Tosdevin 7/24/22)

Plus a few local passerines were out and about after springtime’s busy breeding season ended: Oak Titmouse, Red-winged Blackbird, Common Yellowthroat. Barn Swallows, if they’re here, are always flying around and sitting in highly visible places. The Yellowthroats breed at the lagoon (I believe – I’ve never seen their nest, and I’d be shocked it I did – but they’re nearly always here) but we’ve missed them for the past few months.

Barn Swallow taking some “me time.” (R. Juncosa 7/24/22)

There were also a few especially good birds. Such as the Reddish Egret.

Reddish Egret (Chris Tosdevin 7/24/22)

It’s not that the the Reddish Egret (Egretta rufescens) is terrifically rare in SoCal. They’ve been around for over three decades. The first one I ever saw was in Del Mar (San Diego County) in 1986, jumping around in San Dieguito Creek. If you’re used to the slow and sedate feeding style of most herons/egrets, they’re not like that at all; they jump and dance and chase fish around in the shallow water. They’re a lot of fun to watch. The only heron/egret that’s more fun to watch is the Black Heron (Egretta ardesiaca) of sub-Saharan Africa and Madagascar, which can be easily mistaken for a black umbrella some fool left standing up in the pond. (Notice that genus Egretta has both egret and heron members).

Reddish Egret, searching, searching (Chris Tosdevin 7/24/22)

But there aren’t many Reddish Egrets around and Malibu Lagoon is not at all a reliable place to look for them. I’ve birded at Malibu Lagoon since 1979 and this was the first I’ve seen here. And it was a treat. eBird records the first Reddish Egret at Malibu Lagoon on 1 May 2014, and maybe 95 sightings since then, but most of those sightings are of the same few birds, probably under half a dozen (if anyone knows how many different Reddish Egrets have been at the lagoon, let me know). Birders tend to flock to see this bird, especially if they want to see it in L.A. County. Out of the 313 (or 314, but who’s counting) species on eBird records at the lagoon, the Reddish Egret was #293 in order of date.

Reddish Egret (L – Larry Loeher, R – Grace Murayama 7/29/22)

The Reddish Egret was still there five days later, when Grace and Larry took these photos. As I said, they jump and run around and wave their wings. They do get more reddish than this bird, but mostly on the neck.

Long-billed Dowitcher, 3.5″ shorter than Willet and far less bulky (Ray Juncosa 7/24/22)

The other relatively good bird was the Long-billed Dowitcher. Now, we get them every year at the lagoon, but never in large numbers and not for very long, and this one was in especially colorful plumage, thus nice to see. We could even figure out that it was a Long-billed rather than a Short-billed Dowitcher, which can be far from simple except for birders better than me. [It’s not a “dowager,” as on Downton Abbey. The name used to be dowitchee, doewitch or dowitch, corruptions of Deutsher (German) or Duitsch (Dutch). In England it is (or used to be) called the Red-breasted Snipe. With that long straight bill, they look a lot like snipe.]

Long-billed Dowitcher (Chris Tosdevin 7/24/22)

According to Jon Dunn & Kimball Garrett’s Birds of Southern California: Status and Distribution (1981), along the SoCal coast:
Long-billed presence: Common to abundant late Aug to late Apr; fairly common late Apr to early May & late Jul to late Aug; uncommon early-to-late July; casual or rare individuals early May to early July.

Short-billed presence: Common to abundant mid-to-late Apr & mid-July to mid-Sept; fairly common mid-Mar to mid-Apr, early-to-mid May, late June to mid-July, and mid-to-late Sept; uncommon Oct thru mid-Mar & mid-Mar thru June. They also winter along the coast at a few large marshes such as San Diego Bay and Seal Beach NWS.

For our trips at Malibu Lagoon for 301 trip dates, the sightings are almost even, but the Long-billed outnumber the Short-billed:
Long-billed: 34 visits, 208 birds.
Short-billed: 29 visits, 120 birds.
Here’s a “cheat-sheet” of dowitcher characteristics. Download/print here.
Pretend that you didn’t already know which species it is, and see if you can use it to figure out.

Check the bill-tip on the right-hand bird below.

Long-billed Dowitcher (Chris Tosdevin 7/24/22)

That’s how they grab invertebrates when they shove their bill into the sand or mud. Controllable flexi-tip.

Our last “special bird” was the juvenile Yellow-crowned Night-Heron. It had been reported earlier in the week and we were on the lookout for it all morning, with two adults and six juveniles constantly shifting positions to repeatedly comb through. Finally, lurking on the shore by the Adamson House fence, disappearing and reappearing as it walked between and through the bushes overhanging the water we found it. Chris and Lu went over to see it close-up, instead of from 200 yards away, and Chris got a photo.

Juvenile Black-crowned Night Heron. From a distance we thought/hoped it was the Yellow-crowned. (C. Tosdevin 7/24/22)

No, it’s definitely not a Black-crowned, but it sure looked like one much farther away, when you could only see the top of the bill and a direct frontal view made the bill look short and we could not see the back. (Reasons, not excuses! Reasons!) The breast-streaks did look a little too reddish and wide. So it goes, as famous birder Kurt Vonnegut once wrote.

Least Sandpiper (Grace Murayama 7/29/22)
Western & Least Sandpipers – which is which? (Grace Murayama 7/29/22)

The Snowy Plovers are definitely back, hanging around the southeastern corner of the lagoon. I saw five hunkered down in little hollows in the sand; Chris Tosdevin saw thirteen, and Grace & Larry saw sixteen five days later.

Ruddy Turnstone still in bright breeding plumage. (C. Tosdevin 7/24/22)

By the way, if you see a large, older man drawing on a pad of paper in the meeting area or at the nearby picnic tables, his name is Real. If you’re polite he might show you some of his artwork. His style reminds me of the multidirectional point-of-view (that’s my term for it) work of the First Americans of the Pacific Northwest and the Inuit, blended with the somewhat similar style but far more colorful work of the Australian Aboriginal artists. (I like those artistic traditions, so I’m predisposed to like Real’s work.) He’s very good. Perhaps a local Malibu gallery might be interested in showing it. (Hint, hint.)

Pied-billed Grebe (C. Tosdevin 7/24/22)

Malibu Lagoon on eBird as of 8-04-22: 5981 lists, 313 species.
A question for those of you who use eBird: Is there some way to get sighting dates for a particular species at a particular Hot Spot – say, Reddish Egret at Malibu Lagoon? I can’t figure out how to do it. Their line graphs are useless as far as I’m concerned.

Birds new for the season: Semipalmated Plover, Marbled Godwit, Ruddy Turnstone, Long-billed Dowitcher, Willet, Glaucous-winged Gull, Forster’s Tern, Reddish Egret, Oak Titmouse, Red-winged Blackbird, Common Yellowthroat.

Snag in water is almost submerged (L. Johnson 7-24-22)

Upcoming SMBAS scheduled field trips: Our next trip will be Malibu Lagoon on August 28. This, and any other trip we announce for the foreseeable future will be dependent upon the expected status of the Covid pandemic at trip time. Any trip announced may be canceled shortly before trip date if it seems necessary. By now any other comments should be superfluous.

The next SMBAS program: Zoom Evening Meeting, Tuesday, 4 October 2022, 7:30 p.m. We will continue to Zoom our programs for a while.

The SMBAS 10 a.m. Parent’s & Kids Birdwalk is currently under discussion concerning resumption.

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 Lillian Johnson, Chris Lord, Chris Tosdevin and others for their contributions to this month’s checklist.

The list below now includes a column on the left side with numbers 1-9, keyed to the nine categories of birds at the bottom. The species are re-sequenced to agree with the California Bird Records Committee Official California Checklist, updated 15 Jan 2022. I generally do this sequence update at the start of each year.

Birds & Dinosaurs – Joined at the Hip | Yale News

More evidence that those friendly feathered animals living around, above, even below us, are the direct descendants of those toothy cold-blooded killers who used to rule the world (not counting bacteria).

Birds & Dinosaurs — Joined at the Hip
Yale News | Jim Shelton | July 27, 2022 | 5 minute read

From the article:

All baby birds have a moment prior to hatching when their hip bone is a tiny replica of a dinosaur’s pelvis. That’s one of the findings in a new, Yale-led study in the journal Nature that explores the evolutionary underpinnings of the avian hip bone. It is also a modern-day nod to the dramatic transformation that led from dinosaurs to birds over tens of millions of years.

Link to list of publications by co-author and lab director Bhart-Anjan S. Bhullar
Sample title: The early origin of a birdlike inner ear and the evolution of dinosaurian movement and vocalization. Science 372(6542): 601-609. Hanson M*, Hoffman EA, Norell MA, Bhullar B-AS. (2021).

Link to the paper: The developing bird pelvis passes through ancestral dinosaurian conditions

Living birds (Aves) have bodies substantially modified from the ancestral reptilian condition. The avian pelvis in particular experienced major changes during the transition from early archosaurs to living birds. This stepwise transformation is well documented by an excellent fossil record; however, the ontogenetic alterations that underly it are less well understood. We used embryological imaging techniques to examine the morphogenesis of avian pelvic tissues in three dimensions, allowing direct comparison with the fossil record. Many ancestral dinosaurian features (for example, a forward-facing pubis, short ilium and pubic ‘boot’) are transiently present in the early morphogenesis of birds and arrive at their typical ‘avian’ form after transitioning through a prenatal developmental sequence that mirrors the phylogenetic sequence of character acquisition. We demonstrate quantitatively that avian pelvic ontogeny parallels the non-avian dinosaur-to-bird transition and provide evidence for phenotypic covariance within the pelvis that is conserved across Archosauria. The presence of ancestral states in avian embryos may stem from this conserved covariant relationship. In sum, our data provide evidence that the avian pelvis, whose early development has been little studied, evolved through terminal addition—a mechanism whereby new apomorphic states are added to the end of a developmental sequence, resulting in expression of ancestral character states earlier in that sequence. The phenotypic integration we detected suggests a previously unrecognized mechanism for terminal addition and hints that retention of ancestral states in development is common during evolutionary transitions.

Malibu Lagoon trip is a go, slight rule change: Sunday, 24 July 2022

July 18, 2022

Link to prior announcement here.


  • Bring your mask. You may want to wear it at least during the first 30-45 minutes when the group is a bit compact and crowded. Covid-19 BA.5 variant – the most infectious variant to date (cue Jaws music) – is on the rise, L.A. County has the highest rate in the nation (or so I’ve recently read in the L.A. Times) and L.A. County will probably soon institute mandatory indoor mask mandate.
  • If you feel sick, stay home and isolate.
  • If you have been around anyone who has tested positive for Covid-19, or who is experiencing Covid-19 symptoms, please be considerate of others, and stay home.

High temperature predictions: 70°, 73°, 74°, 74°, 93° (whaaaat?).
(Middlin’) high tide of 3.35 ft. is at 9:09 am!
Dilly-dallying / shilly-shallying? We still have a few openings.

To reiterate a few rules:

  • If I checked your Covid card last month, I won’t check it again.
  • For all others, bring your covid vax card. Yes, I have a list.
  • Trip has a few openings. Send me an email if you want to be on it.
  • Email to Chuck:
  • Masks are not required but are appreciated.
  • Temperature likely to be in mid-to-high 70’s.
  • It will be, as one birder succinctly commented last July: “A trewloue of turtuldowẏs!” 

The prior rules, still in force

  • Registration required, max. 30 people. No drop-ins, please.
  • Bring your Covid-19 Vaccination Record Card and a photo ID card. They will be checked. If you do not have two shots and a booster (preferably three boosters) recorded on your card, you must wear a mask while you are with the group.
  • If we checked your Covid card last month, we won’t check it this month.
  • Bring your own binoculars.
  • All Field Trips are designed to maximize your safety, while also enjoying birds. CDC Guidelines are followed. Participants are encouraged to observe safe distancing, and face coverings are required for those who are not fully vaccinated (2 shots + booster) for Covid-19.
  • Participation in social activities, such as field trips, comes with an inherent risk of exposure to infectious disease. Prospective participants should self-evaluate or discuss with their doctor if their participation merits this risk. If you’re sick or experiencing any symptoms that indicate you might be sick, STAY HOME.
  • The 10am Children & Parents Walk is NOT reinstated. Not yet, anyway.
  • For general questions or help registering, contact Chuck:
  • Additional information on our permanent Covid-19 blog page:

Rebound for bird on edge of extinction |

Plains Wanderer ( | Photo: Owen Lishmund)

A recent survey in northern Victoria uncovered a record number of Plains Wanderers—small, quail-like birds that live only in eastern Australia grasslands, and represent an ancient lineage of birds that evolved in Gondwana more than 100 million years ago.
