Correction to last night’s talk, RE: Snowy Plovers

December 6, 2017
by

Apologies to the audience. I mis-spoke in saying Snowy Plover chicks were “altricial”. In fact, they are “precocial” in the terminology of most biologists. For details, see https://web.stanford.edu/group/stanfordbirds/text/essays/Precocial_and_Altricial.html
This is to say that Snowy Plover chicks are born required to, and able, to find food on their own, and not dependent on feeding by their parent.
Even though I said chicks were required to find their own food, I quoted the opposite term. I apologize for the confusion.

Daddy Longlegs Risk Life … and Especially Limb … to Survive | Deep Look Video

December 2, 2017

When predators attack, daddy longlegs deliberately release their limbs to escape. They can drop up to three and still get by just fine.

The Western Snowy Plover: Natural History and Recovery, with Lu Plauzoles – Evening Meeting Reminder: Tuesday, Dec. 5, 7:30 p.m.

December 1, 2017

Our meeting location is changing to Joslyn Park in
Santa Monica for the December 5 meeting only.
See directions below.

Lu Plauzoles will introduce the Michael Love-produced 45-minute film The Western Snowy Plover: Natural History and Recovery. The movie introduces you to the Snowy Plovers of University of California Coal Oil Point Reserve in Goleta – the most successful breeding colony of plovers on the Pacific Coast. The film includes an excellent introduction to the natural history of the Snowy Plovers by Dr. Cris Sandoval of UCSB and her staff. After the screening, Lu and other SMBAS volunteers will give a short report and answer questions about the Snowy Plovers on our Los Angeles County beaches. ‘Twas a banner year for us!

Lucien Plauzoles (Lu) is a 20-plus-year member of Santa Monica Bay Audubon and has served on the board for over 15 of those years. Having heard Mary Prismon’s pleas for these birds, he was trapped into the Snow Plover project in 2001 by Chuck Almdale’s L.A. County survey, and has not yet escaped its clutches. A graduate of UCLA, he holds two degrees from the venerable local big U — both non-related to the plovers.

However, he has logged extensive hours of observation, monitoring, and reporting of the “little guys,” the smallest avian species on our beaches. He has attended and participated in seven of the range-wide Snowy Plover meetings for the West Coast populations, and regularly represents the SM Chapter and other Audubon volunteers in meetings with the City of Santa Monica, the County and other agencies. He has lobbied for the exclosure (keeps unwanted people and animals out) at Santa Monica for over 10 years and also for the newer Dune Restoration project in Santa Monica, where the first recorded L.A.County nesting of the plovers in 70 years took place this past spring. He is proud to be standing behind the audience this Tuesday as both introducer and postface to the movie.

LOCATION: JOSLYN PARK Auditorium, 633 Kensington Road, Santa Monica
Five blocks south of Pico Blvd., two blocks west of Lincoln Blvd.
If you’re coming from outside Santa Monica, exit the #10 Fwy at Lincoln Blvd., turn southeast, pass Pico Blvd., drive five blocks to Kensington Rd., turn right, 2 blocks southwest to where Kensington turns left and becomes Beverly Ave. Also reached from Pico via 6th St. southeast to Hollister Ave, left on Hollister, left again on Beverly Ave. to Kensington. Park wherever you can.

Link to Google Map

Meeting Room: The auditorium is in the southwest corner of the park adjacent to Kensington Rd. where it turns and become Beverly Ave.

Meetings begin at 7:30 sharp with a little business, and then our main presentation. Refreshments are served afterward. Please leave your coyotes and bobcats at home, however much they whine to come.

Parking:  We’re not familiar with parking at this location. There appears to be a small lot just west of the auditorium, but you’ll probably have to find street parking, which appears to be free after 6pm. Make sure you check the signs – don’t get a ticket! This is a mostly residential neighborhood, so parking may get tight when the locals get home from work. [Chuck Almdale]

 

Migrants still arriving – Malibu Lagoon, 26 November, 2017

November 30, 2017

Brown Pelican adult (R. Juncosa 11-26-17)

Approximately thirty-five birders showed up, maybe a few more. I’ve never gotten in the habit of counting birders, just the birds, but while at the lookout point near the PCH bridge I suddenly noticed there seemed to be an unusually large of people. Too bad more birds weren’t present. Ducks seemed unusually under-represented. We had Gadwall, Mallard, American Wigeon, Red-breasted Merganser and Ruddy Duck with a grand total of fourteen ducks. A typical November would also include: Shoveler, Green-winged Teal, Surf Scoter and Bufflehead, with another 3-5 species possible, and about eighty total ducks. One hopes they’re still somewhere up north, enjoying a warm fall.

Grebes_ Western and Clark’s (R. Juncosa 11-26-17)

The above grebes are typical for this time of year. The Western on left will probably look like this until next spring, with dark plumage surrounding it’s red eye. The area around the eye may become a lighter gray as a few more feathers fall out, but it never becomes white. The Clark’s on right shows no black below the eye except for a thin line leading from eye to bill, with white above and below it. It may (or may not) lose some more black feathers around the eye, making the eye stand out even more.

Green Heron takes a break (R. Juncosa 11-26-17)

We debated a bit about two cormorants standing on the offshore rocks. Both were wet, which can obscure plumage colors. They weren’t Double-crested Cormorants who are happy in the lagoon. Lighting was difficult on this gray and foggy morning, and we strained to see if either bird had the beige chin of a Brandt’s Cormorant. One seemed smaller or slimmer than the other, then again, as it shifted position, it seemed exactly the same. The other seemed to have a tiny patch of beige on the chin, then again, with a minor shift in position. this would vanish. Ray Juncosa snapped a fuzzy photo of the seemingly smaller one as it flew towards the rock. I finally concluded both were Brandt’s with optical illusions obfuscating observation. This species and the Pelagic Cormorant are fairly common on these rocks and swimming nearshore, but they rarely rest within the lagoon.

Adult White-crowned Sparrow, common SoCal wintering bird (R. Juncosa 11-26-17)

Marbled Godwit, head immersed
(L. Loeher, Zuma Beach 11-24-17)

The larger sandpipers – Whimbrel, Willet and Marbled Godwit were as numerous as last month. Most were resting but some were busy foraging. Larry Loeher’s photo from Zuma shows just how involved this can be.

Five Cattle Egrets showed up, resting on the lagoon-edge sand near the cormorants and Brown Pelicans. Unlike other egrets and herons, this species favors open fields over marshes, lagoons and ponds. According to Cornell Lab of Ornithology, this African species first appeared in 1870 in Suriname on the north coast of South America, then spread throughout the Caribbean, Central and South America, and finally into North America. They evolved in Africa, making a living by following the herds of antelope and other grazers, eating insects kicked up by their hooves. In the New World, cattle served the same purpose as far as the egrets were concerned. To a Cattle Egret, lots of cattle equals lots of food. You can see them by the tens of thousands in the Imperial Valley, poking around in the grassy fields, but as Los Angeles County has few cattle munching away, Cattle Egrets can be hard to find. Horses may substitute at times as insect-rousers, but aren’t as reliable. Out of 252 lagoon trips, we’ve seen them 26 times (10%), with a total of 64 birds. As one might expect, when they finished resting and began foraging for food, they headed for the brushy-grassy area, not the mud flats.

Male Great-tailed Grackle (R. Juncosa 11-26-17)

The local Great-tailed Grackles was evident – twelve birds in all. Most likely they breed over in Legacy Park near the shopping center, where (when it’s wet) there are lots of reeds. Several people wondered what the brown birds were. These brown females are 3″ smaller than the 18″ glossy black males, and they can fool you into thinking they’re a different species. Some birders are surprised to see these grackles wandering around on the beach, but they forage on the sand and lagoon-edge quite often, or at least they are much easier to see when they’re on the barren sand than when buried in the brushes or singing in the trees. In case you’re wondering, all grackles are in the Family Icteriidae, better known for its jet-black blackbirds, yellow meadowlarks and orange-and-black orioles.

Great-tailed Grackle female with a rusty breast (G. Murayama 11-24-17)

Thirty-one Snowy Plovers were moderately busy. No banded birds were seen. High tide, their favorite time to forage for invertebrates in the wrack, had been at 9:46 am. A few were active. Most were resting in their tiny dimples in the sand, but every now and then they’d get up and run off to another dimple, for reasons known only to themselves.

Speaking of Royals (British) here’s a nice photo from Grace Murayama of a very royal-looking Royal (Tern), royally robed for winter.

Royal Tern, royally aloof (G. Murayama, Zuma Beach 11-24-17)

Birds new for the season were: Red-breasted Merganser, Ruddy Duck, Cattle Egret, House Wren, Blue-Gray Gnatcatcher, Ruby-crowned Kinglet.

Many thanks to our photographers: Ray Juncosa, Larry Loeher, and Grace Murayama.
