SANTA MONICA BAY AUDUBON SOCIETY BLOG

[By Chuck Almdale]

After eight months in a row of high tides, it was nice to see it low. Sand, mud, pools, puddles, rocks, tide pools, peeps running around, actual beach upon which one can walk. High tides can be exciting with the beach disappearing before your eyes, water rushing in and out the channel, all the birds bunched up on what few square feet of sand remain, the perpetual wondering if all the Malibu Colony houses will make it through “this one” — but everything gets old after a while. Low tide renews the beach, or at least one’s view of it.

Our first surprise of the day were the Black Skimmers sitting with the pelicans and cormorants. We don’t get a lot of Black Skimmers. Every now and then a few drop in: 227 birds in 26 sightings, or 12% of visits out of the past ten years. They need an expanse of calm water in order to catch fish by skimming the surface and snapping whatever they bump into. Malibu Lagoon is a bit small for them and the ocean has far too many waves; they much prefer Upper Newport Bay in the winter, or Bolsa Chica and San Diego Bay where they breed. When they sleep on the sand with their heads and enormous bills lolling to the side, they look dead. If you see this, don’t panic.

There was another surprise in the lagoon-edge line of Brown Pelicans and Double-crested Cormorants.

White Pelicans are even more uncommon. I was certain we’d seen one at the lagoon within the past year or two, but it must have been on a non-census day, as the last one I recorded were two birds on 22 Oct. 2017. Like the skimmers, they prefer calm waters where they can work as a team herding fish into a team. It’s tough to work as a team when there’s only one of you. I don’t know if this bird caught anything. When they’re swimming or resting on the sand their plumage is completely white, but when the get up and fly and all those black feathers appear, it’s a bit of a surprise if you’re not expecting it.

There were ducks, of course; eleven species in fact. Green-winged Teals are expected this time of year, and this is the fifth month in a row for them. I like Ray’s photo above as it show why it’s a “Green-winged” Teal. It’s hard to capture this in a photo as the green speculum is usually hidden when wings are folded. On the Northern Shoveler, like this male below, the baby-blue forewing patch is also hard to see, except in flight. Look closely.

You may be shocked to hear we also had gulls; 324 gulls in 9 species, 73% of them California Gulls. Out of the 5 February months during 2018-2022, three had almost the same total gulls in the mid-300s, while two had more than double that. So it goes, as Kurt Vonnegut wrote more than once.

The Herring and Glaucous-winged Gulls are regular winter visitors in low numbers at the lagoon. [Their relative size above is a photographic illusion. The right-hand Glaucous-winged is actually an inch longer than the Herring.] The both have pale gray backs. The Herring wingtips are black with white mirrors while the Glaucous-winged wingtips are pale gray, about the same shade as the mantle. Herring has a lot of speckling on the neck and a light eye; Glaucous-winged has little speckling and a dark eye. Both have pink legs, a large yellow bill with a prominent gonydeal bump and red gonys spot on lower bill. Most of the Glaucous-winged gulls we get at the lagoon are 1st-year birds, I don’t know how the Herrings that show up there fall out on age.

We also had a few of their cousins, the Royal Terns. These three below show that they can be the same age at the same time of year and still look different.

Our last unusual bird of the day was the Short-billed Gull, which we used to call the Mew Gull after the sound of its call. For centuries it was considered to be the same species as the Common Gull of Europe. In 2021 it was split off and for reasons unknown to me it was named “Short-bill” rather than the perfectly good “Mew.” I suspect that many British Isles people still call their “Common” Gull the “Mew” as that ancient name dates back to Old English. But people would become confused with their unofficial Mew and our official Mew being different species. The British maintain their sense of history and are reluctant to toss out willy-nilly perfectly good names on the basis of a frivolous fad or implausible plaint. They can still call their bird the Mew and everyone there knows what they referring to.

Whatever we call it, it still has a mewing call and a distinctive thin, short bill. This distinctiveness doesn’t stop birders from thinking the occasional skinny-billed Ring-billed Gull is really a Mew. [I know a few such people, myself included.] We don’t get many Mews … er, Short-bills … at the lagoon. They seem to really like sewage outfalls, so I suppose their absence is a Good Thing for Malibu. Ventura, up the coast, has a water treatment facility by their harbor. Behind a chain-link fence near the road they had several large round structures filled with charcoal or some filtration material, and a central arm would slowly rotate dribbling water down onto the charcoal. The Mew Gulls loved those arms with a deep and abiding passion and would sit on them by the hundreds for hours, going slowly around in a circle. If you wanted to see a Mew Gull for some obscure reason, it was an utterly reliable location. Then the facility covered over the top of these structures, preventing gull access (and birder viewing), and another prime birding spot bit the dust. The best local spot I know of now for them is on Dockweiler Beach in front of the Hyperion water treatment facility south of Marina del Rey. Coincidence? I think not.

The swallows are returning. (Don’t tell the people at San Juan Capistrano this, lest they become apoplectic with rage or envy. They think swallows return on March 25 every year, no matter what.) The SJC swallows are Cliff Swallows, like these below. They build nests of mouthfuls of mud, globbed (a technical term) onto a wall or underside of a bridge and the like, one glob at a time. The resulting cup of mud globs holds the chicks. They used to nest in great numbers on the outside of the stone walls of the San Juan Capistrano Mission church. But the people who run the church did some … ahem … improvements … a few years back and the swallows didn’t like the results and for the most part stopped nesting there. I don’t know the swallow situation at the church these days. Maybe they forgave the church Fathers and nest there again. Maybe not.

About 20-30 years ago we had a big El Nino winter and so much water came down Malibu Creek carrying logs and rocks and whatnot that the Pacific Coast Highway bridge was dangerously damaged. The highway crews re-built most of it, but whatever process they used to make the walls of the supports was very swallow-unfriendly. Too smooth perhaps. The nests used to be abundant there; now there are few-to-none during nesting season. What Cliff Swallows we still have nesting in Malibu now use the Civic Center and shopping center walls. Think about that next time you built a bridge in Cliff Swallow Country (like the entire central valley of California), road engineers, OK? Leave the walls a little rough for the nest’s mud to adhere. Bugs bite people, especially movie people (everyone knows that!); swallows eat bugs; win-win (except for the biting bugs, who lose).

Birds new for the Season: Cinnamon Teal, Northern Shoveler, Mourning Dove, Short-billed Gull, Black Skimmer, Brandt’s Cormorant, American White Pelican, White-faced Ibis, Cooper’s Hawk, Say’s Phoebe, Northern Rough-winged Swallow, Cliff Swallow.

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 Chris & Ruth Tosdevin, Ray Juncosa, Chris Lord 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, which was updated 4 Feb 2023. If part of the chart’s right side is hidden, there’s a slider button at the bottom.
