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.

Antelope Valley Raptor Search – Field Trip Report, 9 Jan. 2010

January 9, 2010

Jan 9, 2010. Our raptor search began across the street from the curiously birdless Desert-Aire Golf Course with some nice non-raptors, a field full of Mountain Bluebirds including some stunningly beautiful males.

Singing LeConte's Thrasher (L.Johnson 1/10)

We then tooled around looking for whatever was to be found, dodging the flatland speedsters on their way to elsewhere. Red-tailed Hawks were numerous and varied, including several extremely dark birds with black bellies and under-fore-wings, and dark red breasts. At the Ave. K wash between 50th & 70th Sts. east, we walked several hundred yards south until we ran  across a LeConte’s Thrasher (a lifer for some) who was nice enough to get up and sing for us. We also had a Rock Wren and our first of at least 6 Loggerhead Shrikes, scattered in singletons around the valley.

Guess the bird! (L.Johnson 1/10)

The large grassy field on the SE corner of I & 110th E had the reported many dozens of Mountain Plovers, plus many Killdeer, hoards of Horned Larks, at least a dozen Long-billed Curlews and many Western Meadowlarks.

After seeing this, we went to lunch. (C.Almdale 1/10)

A Merlin perched across the street on a handy Joshua Tree permitted a few photos,

while a Ferruginous Hawk kept the plovers on their toes. The hawk was more interested in rodents however, as we watched him dive and capture one and eat the whole animal in one gulp.

We checked a tamarisk grove at H & 110th east that harbored a Long-eared Owl several years back, but the trees hadn’t fully recovered from a fire and lacked enough protective foliage to shelter any birds. After lunchtime at the Saddleback Butte campground, with very pleasant weather (no wind, about 55° but feeling warmer in the sun) and cookies from Carol, we headed to Apollo Park. We found a variety of ducks there, a lot of Canada Geese, and some Dark-eyed Juncos we hadn’t yet seen.

Pink cloud at night, Birder's delight. (C.Almdale 1/10)

A Rough-legged Hawk dashed in front of the cars as we rounded a bend at the SW corner of the Poppy Preserve. We stopped and watched it fly on out of sight around a hill, never to return.  It may not sound like we’d done much, but with all the starts and stops, Horned Larks and  various blackbirds, we’d managed to while away about six hours, so we headed on to Holiday Lake near Ave. D and 260th west, passing a Northern Harrier on the way. The lake was full of Canada Geese, plus some Mallards and Green-winged Teal. At least two dozen Black-crowned Night Herons emerged from the reeds and roosted in the trees, as it was just beginning to get dark. A Marsh Wren worked the reeds at water’s edge. Chris found a Red-breasted Sapsucker working over a tree; Great-tailed Grackles called as Jean spotted a Great-horned Owl roosting in a tree across the lake, staring at the humans jabbering away.

While heading on to Gorman to refuel, we spotted a Prairie Falcon landing in a tree, dark wing-pits and all. All told, we drove about 220 miles, birded for almost 9 hours, spotted 56 species including 9 raptors.
