Winter’s Icy Chill Strikes Malibu Lagoon, 24 December, 2017

The elegant Pintail used to be more common in the late 1970’s. (R. Ehler 12-24-17)

A surprising number of birders appeared, considering that it was Christmas Eve Day, and it was chilly. (57°F or 14°C is considered chilly around here. This blog’s title is tongue-in-cheek). We had a good assortment of birds, although all did not appear at the same time nor did everyone see all of them. The Merlin, for example. The first I heard about it was when I was asked: “Wow! Didja see that Merlin! What a show!” Well…no I didn’t, but thanks for asking. Once gone, apparently, gone forever.

Congener Phoebes: Say’s and Black, typically over-winter at the lagoon
(R. Ehler 12-24-17)

We had some people new to birding, and some birders new to the lagoon. Thus, plenty of questions and plenty of new birds for some of us. A cluster of (three, I think) birders had just finished a beginning birder’s course with Pasadena Audubon, and the gulls and shorebirds seemed to be new to them. As a reminder to our readers, our chapter has a beginning birding class beginning soon, but it might already be full.

Some ducks showed up, finally, so I guess the weather up north became a bit more wintery. I’ve recently read that some West Coast sea counts (stand on a seaside high point and count birds flying by) of ducks were down about ninety percent from prior years. That sounded about right to me. But today we had eight species of duck, two of grebe and two of loon. Not large numbers of any particular species, but good diversity.

Snowy Plovers a-plenty on the beach. Thirty-five of them, scattered widely through the washed-up detritus and footprint-hollows landside of the beach berm, including banded birds AA:BG and RR:BB, the latter bird spotted by Chris Lord.

Double-crested Cormorants in the lagoon, Western Gull preening (R. Juncosa 12-24-17)

Gulls were numerous. Most were California Gull, which is to be expected, but we also had one Bonaparte’s, one Mew (reported to me), Two Heermann’s, one Herring and two Glaucous-winged. Royal Tern was the only tern species. Forster’s and Caspian Terns must be around, somewhere, but the Elegants have fled to Baja for the winter. The larger shorebirds – Willet, Whimbrel, Marbled Godwit – have dwindled in numbers by about 70% since last month.

One or two of the heavy-billed Common Loons were swimming around in the now-shallow lagoon waters. Shallow because the beach was breached during a recent high-tide, most of the water ran out, the water level dropped a couple of feet (estimated) and the water surface area is probably half of what it was a month ago.

Speaking of water, the current drought and low humidity is really affecting plants and trees everywhere, causing them to dry out and encouraging all our recent wildfires. The “Thomas” fire had become the largest wildfire in recorded California history – over 280,000 acres (450 square miles), and many homes gone. Many of the bushes look extremely brown and wilted. The tree by the picnic area died and fell over. Someone dragged it out of the path. Downtown Los Angeles had 0.11 inches of rain for Nov-Dec, 94% below normal.

Bewick’s Wren – pronounce it “Buick” or he gets upset – are usually up in the chaparral (R. Ehler 12-24-17)

On my way out I met a birder, who asked if I though the bird he was looking at was a Cooper’s Hawk. It was on the ground on the small island near our gathering spot. I do not expect to find Cooper’s Hawks on the ground, sitting quietly, doing nothing. I’ve seen them on the ground while eating some hapless bird or rodent, such as the one disassembling and scarfing a rat in my backyard one recent winter. But we agreed that it was a juvenile Cooper’s. Sometimes juvenile raptors haven’t quite figured out how to catch prey. I’ve seen juvenile Red-tailed Hawks chase squirrels by hopping around on the ground, and a juvenile Great Black Hawk in the Peruvian Amazon trying – completely unsuccessfully – to grab any one of over a dozen Hoatzins resting in a fallen riverside tree by jumping ungainly from limb to limb.

Nick, the birder, turned out to be an Ornithology student at San Diego State, visiting locally for Christmas. While I was making my best attempt to tell him how to get to the Ballona Creek jetties to see rocky shorebirds, we spotted a small falcon diving on the Cooper’s Hawk. It was a Kestrel. I haven’t seen a kestrel at the lagoon since 9/25/16, fifteen months ago. Then, to top even that, while talking to Lu Plauzoles in the parking lot about his waste fishing line collection efforts on the Malibu Pier, he spotted a Nuttall’s Woodpecker female whacking away in a nearby tree. This is only the seventh Nuttall’s we’ve spotted at the lagoon in almost forty years; the last one was in October 2015.

Blue-gray Gnatcatcher, another species usually up in the chaparral (R. Juncosa 12-24-17)

Apropos this unusual woodpecker coastal sighting, Lu commented that he had heard a conjecture from knowledgeable and local birder Dick Norton that the drought, dying trees and lack of invertebrate prey had forced many birds to flee local hills and chaparral and seek food elsewhere. Lu thought this might be why the woodpecker, the Blue-gray Gnatcatchers and Bewick’s Wrens were around the lagoon in larger than usual numbers this year. He may be right.

On the other hand, Chris Lord – SMBAS member, regular birder at Topanga Canyon and monthly bird census participant at Ballona Freshwater Marsh – had this comment after reading my original posting.

Concerning your Malibu Lagoon write-up and comment on Blue-gray Gnatcatchers [BGGN], my local experience is that many BGGN winter nearer sea level and are absent in winter up in Topanga State Park [TSP], at least in my counting area; then they reappear there in TSP for spring and summer. I have never learned if these are mostly local birds in vertical migration or not. At Ballona Freshwater Marsh (BFM) we count roughly 5 to 10 BGGN per monthly winter count, and I get 3 to 14 BGGN per Topanga State Park count, starting mid-March and peaking in mid-August. I don’t know why we don’t see more wintering at the Lagoon. Maybe there are more at Legacy Park [an inland park a short distance from the lagoon]? They sure like BFM, maybe for its larger habitat area.

Another mystery of nature as yet unsolved. [Sounds like a future PhD thesis to me.] Whatever is really going on, let’s hope there’s some rain in our near future.

A young White-crowned Sparrow (R. Ehler 12-24-17)

Birds new for the season were: Surf Scoter, Bufflehead, Bonaparte’s Gull, Herring & Glaucous-winged Gull, Pacific & Common Loons, Osprey, Cooper’s Hawk, Nuttall’s Woodpecker, American Kestrel, Merlin, Barn Swallow, California Towhee.

Many thanks to our photographers: Randy Ehler and Ray Juncosa.

Our next four scheduled field trips: Santa Monica portion of Los Angeles Christmas Count, 6:45 am, 2 January; Antelope Valley Raptors & Other Specialties, 7am carpool time, 13 January; Malibu Lagoon 8:30 & 10am, 28 January; Salton Sea & Imperial Valley, 9am, 10-11 February (a sign-up trip).

Our next program: The Salton Sea, with California Audubon – Evening Meeting: Tuesday, Feb. 6, 7:30 p.m., Chris Reed Park, 1133 7th St., NE corner of 7th and Wilshire Blvd. in Santa Monica.

NOTE: Our 10 a.m. Parent’s & Kids Birdwalk meets at the shaded viewpoint just south of the parking area. Watch for Willie the Weasel. He’ll be watching for you and your big floppy feet.
