Malibu Lagoon turning to autumn, 24 Sep. 2023

September 29, 2023

[By Chuck Almdale]

Mirroring Malibu Lagoon (Ray Juncosa 9/24/23)

The day started off nice and cool at 58°F. Three hours later it was 74° with very little wind as you can see by the mirrorlike lagoon above. So what season is it?

As you can see below, we had a good mixture of shorebirds and gulls on the east side of the lagoon near Adamson House. We’ll go through some of them farther down.

Seven Marbled Godwits, three Willets, but who’s counting?

Which Whimbrel is real, which is illusion? (Ray Juncosa 9/24/23)

This was one of those days of the lunar month when the tide doesn’t fluctuate much; from the high at 7:39 am to the low at 11:53 am it only dropped .74 feet, or 9 inches. The tidepool rocks, never entirely covered, became slightly more exposed and those shorebirds inclined to do so, explored the shore.

This Black Oystercatcher seems to have exceptionally fat toes.

Oystercatchers are definitely easier to find at Malibu when the tidal rocks are exposed, although occasionally we’ll see them on the large outer offshore rocks.

…and a Black-bellied Plover about as far into basic (non-breeding) plumage as they can get, wandering away from the crowd (Grace Murayama 9/20/23)

Elsewhere around the lagoon and its edges, there were butterflies.

Butterfly (Ray Juncosa 9/24/23)

[Addendum]: I originally identified the above butterfly as Monarch (Daneus plexippus), although I was only 98% certain and Lillian much less so, as she suspected it was a Queen (Daneus gilippus). I soon received separate comments with varying levels of certainty from two readers, Jeri Edwards in San Luis Obispo and Ruth Dewar, with the same opinion, that it was actually a Queen, the closely-related and ridiculously-similar congener. [Jeri, by the way, ran the outhouse roof vent owl poo-poo project a few years back which SMBAS supported.] I examined the photos again and decided Jeri and Ruth were probably right, although I’d still like to hear an expert chime in with exactly why it’s a Queen. Anyway….grumble, grumble….Jeri kindly sent Ray’s three photos to iNaturalist. They officially identified it in their iNaturalistically way as a Queen Butterfly Danaus gilippus (Cramer, 1776), and it’s now got it’s own iNaturalist page, preserved until the End of Days. Like the Monarch, they also lay their eggs on milkweed, and now I’m wondering if all the Monarchs I’ve seen in SoCal are actually Queens. Here’s a map from it’s page:

I also sent the photo to NABA (North American Butterfly Association) of Orange County (L.A. County doesn’t have a chapter I could find), and Lee Shoemaker wrote back: “This is a female Queen. They are not common near the coast and are most common in California in our deserts. Great find.

…and at least three Green Herons scattered in various locations. They don’t often gather in groups. Wondering where the green is?

Green Heron (Chris Tosdevin 9/24/23)

I finally laid eyes on a Nuttall’s Woodpecker at the lagoon, although Femi Faminu seems to either see or hear them almost every trip. This one was, to my great surprise, in a palm tree in the back of the colony, not in a hardwood sycamore or oak as I (perhaps I’m the only one who thinks this) would expect. It was just below the base of the fronds, poking – and I suppose pecking – around the large bulge encircling the top of the trunk where the older fronds have been trimmed away. Alas, no photos – it was very dark under those fronds.

A Pied-billed Grebe, just after surfacing. Based on the bill and throat colors, I’d say this is a juvenile bird, born this year.

We should call these confusing fall Red-winged Blackbirds. I think they get mistaken for Rusty Blackbirds every now and then.

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 Ray Juncosa, Chris Lord, Chris Tosdevin, Ruth Tosdevin and others for their contributions to this month’s checklist.

The species lists below is irregularly re-sequenced to agree with the California Bird Records Committee Official California Checklist. If part of the chart’s right side is hidden, there’s a slider button at the bottom of the list.

    Thanks for sending this each time! Not to be grouchy, but the Monarch butterfly shown here is actually a Queen Butterfly (Danaus gilippus). You could look it up. Cheers Ruth Dewar

      I did look it up, both before and after writing the blog. You’re the second to observe this. It’s now noted on the blog it might be a Queen, and after further study I’m leaning towards Queen. I’m not good on butterflies, and I’m waiting for someone to say WHY (definitive field marks) it’s a Queen and not a Monarch. It seems to have characteristics of both.
