Oystercatchers at Malibu Lagoon, 22 February 2021

February 28, 2021

The weather really was perfect. The temperature started at 65°F at 9am, rising to 74°F by 11:30. A slight breeze rose as the day warmed, keeping it very pleasant. We never needed to add or shed clothing. While descending Malibu Canyon Road we saw a light brown haze stretching south from Santa Monica over the bay, but at sea level we couldn’t see it, and the sky was a cloudless pristine blue.

Very few, if any, surfers graced the water. Tide was very low, heading lower to -0.13 ft. at 1:14pm. A high-pressure zone in the desert was blowing from land to sea, hence the smog layer. When there’s little swell, such winds flatten whatever waves there are. I saw one paddleboarder over by the pier.

There were seven birders, all masked – save for one nose – and ready to bird. Bring ‘em on!

Well…we had a good variety of ducks, a fair number of gulls and good diversity but low counts of shorebirds, but the passerines were conspicuous by their absence. Not even a mockingbird!

A Great Egret stayed very close to the picnic area behind Malibu Colony. We speculated whether it could reach into the trash bin (probably couldn’t), then discovered why it was there, when it caught and ate a lizard. (Photos: L – C. Bragg, R – R. Juncosa 2-22-21)

I would not be surprised to find at least two pair of Canada Geese nesting this spring at the lagoon. They seemed to quite like the easternmost sand & brush island – one pair at each end – but last month a pair seemed to be very interested in the area near the “osprey perch” at the western island’s east end. With eight geese honking and fighting, if they pair up there’s plenty of room.

By the time we got to the ocean, the tide was really, really out, with perhaps more rocky reefs exposed than I’ve ever seen before. [I have a sneaking hunch that I think this every time the water is really low.] Back home, I checked to see how accurate this memory is. Not bad, as it turned out. During the exactly 200 visits since 6/27/04, there have been only 17 dates with negative tides, the lowest being -1.10 ft on 4/23/13 (on-line table now says -1.06 ft). So…today’s -0.17 ft. was not the lowest, but not far off.

The high offshore rocks near the Malibu Colony had an assortment of cormorants – five Brandt’s among the Double-crested, plus a sleeping Harbor Seal at the other end, well away from the potentially noisy and annoying birds. Several of the Brandt’s had breeding-blue gular pouches and white cheek plumes. These birds usually leave about the time they develop these features, so we don’t see them every year.

Bath time for Black Oystercatchers (R. Juncosa 2-22-21)

The most interesting birds were the oystercatchers – three Black and one not-Black. They were all out on the exposed rocky reefs among the gulls. The three Blacks even left the rocks and ran around on the sand, unusual for Oystercatchers. One even took a bath in the waves with a gull. Quite astonishing!

I wrote a long blog in March 2020 about the oystercatchers at and around Malibu Lagoon so if you want to know everything I know about them, read it here. It’s a tricky call. “Frazar’s” American Oystercatcher breeds around the Sea of Cortez and on the west coast of Baja, and they look very much like our bird here. Black Oystercatchers also breed on the west coast of Baja and will hybridize with the Frazar’s. They do not hybridize with Frazar’s breeding around the Sea of Cortez. In Southern California we can have four types of Oystercatcher: Black (by far the most common), full American (least common, coming from Gulf of Mexico), Frazar’s (either side of Baja), and hybrid Frazar’s/Black (west coast of Baja).

Hybrid Oystercatcher or American “Frazar’s” Oystercatcher (H.p.frazari) — a close call.

A bird rated 30 or higher on the the Jehl Scale is supposed to be an American. I rate this bird overall 28-33 of 42 points. Some criteria are difficult to impossible to see. Upper Tail Coverts – 2-3, Tail – 2, Chest – 3, Belly – 6, Under Tail Coverts – 3-4, Thighs – 4, Greater Secondary Coverts – 2-3, Extent of Primary Wing Stripe – 1-2, Underwing Coverts – 2-3, and Axillars – 3. The Jehl Scale is given at the end of the March 2020 blog, and can be downloaded or printed here.

This bird, in my inexpert opinion, is on the borderline between Hybrid and H.p.frazari. I feel it ought to have a bit more white going up the shoulder between black breast and wing. I also think this is one of the birds in the March 2020 blog, which I couldn’t reach a firm conclusion on. It probably spends most of it’s time along the wet rocky areas within a few miles of Malibu, and drops in at Malibu when the tide is low.

I waded across the outlet stream, opting for wide and shallow rather than narrow and deep. The water rose halfway up my shins — more where the sand was very soft and I started sinking in. Icy cold! I though my feet had fallen off by the time I got across. The point of crossing was to search all areas for Western Snowy Plovers which we hadn’t seen on our trip down the wide beach. Of course there were none. Back across the stream and westward we walked, finally finding 27 birds in their little sand-pockets, inland of the berm.

The next three SMBAS scheduled field trips: Who knows? Not I.
The next SMBAS program: March 2, Changes in Bird Status in California’s Central Valley, with John Sterling, on ZOOM, 7:30 PM.
The SMBAS 10 a.m. Parent’s & Kids Birdwalk is canceled until further notice due to the near-impossibility of maintained proper masked social distancing with parents and small children.

The 10-year comparison summaries created during the Lagoon Reconfiguration Project period, despite numerous complaints, remain available 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.
