Malibu Lagoon Trip Report: 24 January, 2010

January 24, 2010

Clear and cold conditions at the start:

Peregrine Falcon (prob. ss. anatum) [James Kenney 1/24/10

at 8:30, the temperature was about 41 and a light breeze stirred the leaves. By 11:00 the temperature had risen to 65, the breeze was gone and we were carrying rather than wearing our coats and sweatshirts. Large waves broke over the  offshore rocks; the large flotilla of surfers appreciated the action. Our recent rains (6 – 12 inches, depending on where you live) had scoured the lagoon bottom of sand and blew a big outlet through the east end of the beach, leaving exposed gravel all over the lagoon floor. Side channels were drained of water with little but mud remaining. We were very surprised to find, close to the almost 1000 gulls resting on the gravel, two Peregrine Falcons. [Local photographer James Kenney managed to get an excellent photo of one of them, resting between swoops and stoops, as it perched on the sole remaining snag in the lagoon.] The gulls, ducks, shorebirds, grebes, pelicans and cormorants completely ignored them until one decided to get up and take a few swoops at the flock: that got them moving in a loud and colorful burst of wings. We eventually arrived at the far end of the beach closest to the pier where we spent a long time scoping for the Long-tailed Duck (sans long tail) that’s been there since Christmas day, and admiring the six Black Skimmers and two Black Oystercatchers (uncommon visitors to the lagoon) on the exposed gravel down near the tidal zone. We eventually found it, actively diving among the scoters and grebes over near the end of Malibu Pier, noticable primarily by its blotchy pale plumage and smaller size. On our way back we came across 6 Glaucous-winged Gulls, an average number for January. A pair of American Avocets were feeding among the Willets  in the lagoon,   Altogether we had a nice count of 70 species with 1,906 birds, most of them gulls.

Winter Snowy Plover Survey

January 17, 2010

Banded Snowy Plover on SM beach 2009.

The range-wide survey of wintering birds started today along the entire Pacific Coast from Washington to the Tijuana Slough. It continues through the 23rd of January. There may also be some counts conducted in Mexico. This effort is led by the US Fish and Wildlife Service whose Arcata, CA office has become the de facto nerve center for the recovery effort of the threatened species. Locally in Los Angeles County there are 6 sites considered key because of repeated sightings of the birds from late July through April each year. Zuma Beach is the northernmost and hosts the largest population. Malibu Lagoon is often the second most populous, but, by this morning’s count, Santa Monica Beach with 49 birds, may become the second largest roost. Thanks to counters Erin Rowan and Allison Brandin for their assistance with the Santa Monica Beach count. Lu Plauzoles

Happy 2010 to one and all ! We have been reaping the benefits of living in Southern California – birding has been wonderful and some plants have been sprouting and the sun has been shining – we have been having “Rose Bowl Days”. We hope to have winter next week – we dearly need rain and snow pack in the mountains.

Christmas Counts have been done around the country – the results are not in as yet. The next big milestone is the 13th Great Backyard Bird Count February 12-15, 2010 – check out www.birdcount.org – another little step of citizen science. Interesting to note the top bird reported in the 2009 GBBC was the Northern Cardinal – we need to report more Western birds !

Come join us for our month end fourth Sunday Malibu Lagoon walk, come to our first Tuesday General meeting, join us for our field trips – enjoy the birds, enjoy the weather, enjoy the people – learn and participate.

Best of birds in 2010.

Native Plants

January 12, 2010

 It’s spring, and in spite of the drought, some chaparral plants are bravely in bloom. One of the commonest is Purple Nightshade (Solanum xantii), named in honor of the same Xantus as Xantus’ murrelet. The genus Solanum is large, including  potato (Solanum tuberosum) and eggplant (Solanum melongena), as well as several more-or-less toxic species, of which Xanti is one.  The green berries are the most toxic part of  xanti.  I haven’t tasted the berries.

Douglas’s Nightshade, which has smaller, white blossoms, comes into bloom later and has shiny, black berries that are edible when fully ripe.

Don’t confuse “our” nightshade with the European occurrence, DEADLY NIGHTSHADE, which is in the genus Atropa, an entirely different family. As few as three berries of this plant could kill a small child. It’s not surprising that Deadly Nightshade is rarely grown in California.
