Snowy Plover Update for northern Los Angeles County
The following message appeared on LACountyBirds on Sunday, Nov. 14, 2010. As a recent field trip report refers to the absence of Snowy Plovers at Malibu during our regular 4th Sunday of the month Malibu Lagoon birdwalk, I thought I’d share this with everyone, as you may not be a subscriber to the LACoBirds web chat.

***************************
It does appear that only a few snowy plovers were observed at Malibu Lagoon between October 23 and November 10. The good news: we surveyed the three northern roosts at Zuma, Malibu Lagoon and Santa Monica, using the snowy plover survey protocol, on Friday (11/12/10) and found 143 snowy plovers among the three roosts, including 47 at Malibu Lagoon. For comparison we found 162 at these three roosts in October and 134 in September. We have observed large roosts relocate in the past and have noted that in some years, most birds remain at the main roost sites, and in other years they are more scattered. We haven’t come up with any definitive reason or observed anything out of the ordinary that might have caused the temporary relocation.
If anyone is interested, we are going to hold our annual Snowy Plover volunteer training on Saturday, January 8, 2011. If you are interested in becoming an LA County Snowy Plover monitor or docent, please contact Stacey Vigallon at LA Audubon off the listserv at (svigallon@hotmail.com). We expect the USFWS winter window survey to be during the second week of January next year, followed by surveys in March, May, and September. [Thomas Ryan]
Malibu Lagoon Restoration to Benefit All
There has been some recent controversy concerning Malibu Lagoon. A petition, circulated among local citizens and lagoon visitors, objected to planned changes to the lagoon configuration. In my personal opinion, the presenter of the petition made it sound as if these plans came out of nowhere, a surprise foisted upon an unsuspecting public. In reality, the upcoming changes are Phase Two of a plan which has been in the works for many years, and involved representatives of all of the concerned local NGO”s and governmental divisions. The lagoon has had problems for many decades: no one is completely happy with the current situation, and no one is completely happy with the proposed plans. Yet something needs to be done, and this was the best solution which could be agreed upon by the various involved parties.
High tide in 1st channel (L.Johnson 2/10)
An excellent article, written by Suzanne Goode, Senior Environmental Scientist for California State Parks, Angeles District, appeared in the Public Forum of the Malibu Times on October 6, 2010. It describes just what is actually planned for Malibu Lagoon, and why. The first paragraph is presented below, followed by a link to the original article. I encourage all interested parties to follow the link and read the entire article. [Chuck Almdale]
***********************
We are writing to set the record straight on the Proposed Phase Two of the Malibu Lagoon Restoration Project, which is the fruition of a comprehensive planning effort that began over two decades ago. Understanding the importance of Malibu Lagoon, California State Parks undertook its initial restoration in 1983 and removed baseball fields located on artificially filled historic wetlands, created three tidal channels, planted salt marsh and other native vegetation.

Malibu Lagoon Trip Report: 24 October, 2010
It’s only late October, but you know winter is definitely on its way when the temperatures plunge way, way down into the low to mid 60’s. And they say California is always sunny and warm. Who’re they kidding? Who are they, anyway?
Yours truly was out-of-town, so I, personally, haven’t much to report. Fortunately, our trusty Conservation Chairman and renowned Snowy Plover enthusiast, Lu Plauzoles, did the monthly census. He reports that bird numbers were reduced, probably due to the full moon high tide. Sand had closed the lagoon outlet, so the group was able to continue down the beach to Adamson House, where workers scurried about prepping for yet another installment in the endless sequence of weddings which occur there.
Brown Pelican flying low (C.Bragg 5/10)
The most uncommon bird was the single Herring Gull. We regularly see this species, which is abundant on the Atlantic Coast, during the winter, but usually in one’s and two’s. Occasionally their numbers spike: we recorded 35 of them on 4/25/81 and 3/27/94. The 30 Long-billed Dowitchers was also unusual; this species doesn’t spend much time at the lagoon, probably because the often-anaerobic conditions in the lagoon bottom makes foraging for invertebrates unrewarding for them, and so they go elsewhere. [See article on Lagoon restoration which addresses this problem, among other problems.]
The Brant which had spent six months at the lagoon finally disappeared. Also absent was the roosting colony of Snowy Plovers, most likely due to the high tide which had just washed completely over the beach where they normally roost and into the lagoon. Lu later discovered that the Snowy Plover colony on north Santa Monica beach was significantly larger than usual, so we think that some of the Malibu birds had (probably temporarily) relocated to that much wider beach, safely above the surf. Our records of banded birds has proved in previous years that there is movement between these two colonies and the colony at Zuma Beach. [A news update on the Snowies is here.]
The July-Oct chart below will grow monthly through December, but six months of data is all I can squeeze into this blog format. For prior periods, follow these links to Jan-Jun‘10, Jul-Dec‘09, and Jan-June‘09. [Chuck Almdale]

Unusual Birds at Malibu Lagoon
Occasionally Malibu Lagoon gets an uncommon avian visitor. When we receive photos of these birds, we try to get them into an appropriate and upcoming blog/email, such as an announcement of an upcoming field trip. To reduce blogsite clutter, these announcements are deleted after the trip has run, but we hate to lose any interesting photos they may have contained. So we’re creating this blog as a permanent record of these photos. It will change when we add photos, but you won’t receive an email notification of such changes. You’ll just have to check back! New submissions always welcome. [Chuck Almdale]

October Thoughts
Did you know that the California Condor population in the California wild hit 100 ? A milestone ! In 1982, there were 22 wild condors in the state. The populations of Arizona, Utah, Baja Mexico and California now total near 400 and we hope the number is growing.
Did you know that the top waddle speed of the Antarctic Emperor Penguin is 1.7 miles per hour ?
(Source – Stanford Dept. Of Geologic and Environmental Science)
Did you know where the Zenaida Dove got its name ? It was named in honor of Zenaida Laetitia Julie Bonaparte. She was the daughter of Joseph Bonaparte (Napoleon’s brother) and she married Charles Lucien Bonaparte – her cousin- which made her Princess Zenaida Bonaparte Bonaparte. Her husband was an ornithologist (he had a gull named for him)and he named the doves for his wife. If you want to see her, there is a beautiful portrait of Zenaida and her sister Charlotte by Jacques -Louis David at the Getty Museum ( West Pavilion – second floor – European paintings)
This October is having unusual weather – stick native plants in the ground and take advantage of the rain.
See you soon and stay dry, Ellen
