Malibu Lagoon Trip Report: 28 October, 2012
Don’t forget to visit our new page for the Malibu Lagoon 2012 Project, frequently updated with new photos. We just added a new interview with Suzanne Goode, Also look for the link to the plant revegetation list.
The Malibu Lagoon reconfiguration continues apace, as you’ll see from some of the photos in the slideshow above. According to Don Harvey in Bob Purvey’s interview of 10/24/12, now on our Project Page, over 25,000 plants have been implanted and are being sprinkled until the rains are more dependable. You can’t really see them yet, but that forest of flags marks their locations.

Trip leader Lu Plauzoles reports that weather was sunny and warm, not unusual for October. Migrants continue to arrive, including: American Wigeon, Horned and Clark’s Grebes, Black-crowned Night Heron, Dunlin, Glaucous-winged Gull, Belted Kingfisher, Say’s Phoebe, Ruby-crowned Kinglet, Yellow-rumped (Audubon’s) Warbler, Savannah & White-crowned Sparrows, and Western Meadowlark. The Elegant Terns, so numerous for the past 6 months – peaking at 240 in June – have dwindled down to two and will likely be off to warmer climes in November. Duck and gull numbers continue their fall increase. Coot numbers remains high as always, probably to taper off next March.
Snowy Plover PV:YB (left leg Pink above Violet: right leg Yellow above Blue) was found on Surfrider Beach last Monday, 10/22, by alert SMBAS photographer Joyce Waterman. [The violet ring is just barely visible.] We sent this photo to Pt. Reyes Bird Observatory which informed us that PV:YB was born this year at Oceano Dunes (near Pismo Beach) where it was banded as a nestling, then later seen at Guadalupe Dunes in August, then on Surfrider in September. If you see it on the beach, give it some room, and it will likely spend the winter with us.

Comments on Bird Lists Below
Total Birds: Oct. total birds of 1099 are 3% above average (Jul – Sep were all down), an insignificant amount. Brown Pelican numbers remain down, probably due to the large west coast die-off due to lack of food. Sanderlings, Terns, Yellow-rumped Warblers and Red-winged Blackbirds are well above average. Monthly total bird numbers have been up & down, up & down during the project so far.
Species Diversity: Of 104 total species appearing in October for 2007-12, no more than 62% of them appeared on any single day. Whenever you visit, expect to see about 5/8ths of what is possible at that time of year. October 2012 with 64 species is 5% above average, an insignificant amount. All 9 categories of birds were about average. Passerines were up slightly despite the lack of vegetation, probably the result of a more alert trip leader.
Summary of species diversity from the 6-year average so far: May +4%, June -10%, July +10%, Aug. -6%, Sep. -20%, Oct. +5%. The only constant is change. It will be interesting to see the results when the project is done, the workmen are gone and the vegetation is beginning to grow. [Chuck Almdale]

Full Hunter’s Moon 10/29/12 12:49 a.m. PDT
Here’s another update from SMBAS Blog on that large, disc-like, shining object which has frequently and mysteriously appeared in our nighttime sky this year (known to many as the moon).
Oct. 29, 12:49 a.m. PDT — Full Hunter’s Moon. With the leaves falling and the deer fattened, it is time to hunt. Since the fields have been reaped, hunters can ride over the stubble, and can more easily see the foxes and other animals that have come out to glean and can be caught for a Thanksgiving banquet after the harvest. [Top 10 Amazing Moon Facts]
The Chinese see a rabbit rather than a man in the moon. Look for the rabbit. It might take a while.
The next significant full moon will occur on Nov. 28, 6:46 a.m. PST. Keep an eye on this spot for additional breaking news on this unprecedented event.
This information comes to you courtesy of:

Plover Month at National Audubon
In honor of Plover Month at National Audubon, we have created a new blog page devoted to Snowy Plovers. So far it features a multi-part article, updated since originally published in Malibu Patch last summer.
California Audubon is embarking on the Bird of the Year campaign again. This year, Western Snowy Plover is one of the candidates, and we hope all of you will vote for it as the Audubon Bird of the Year. Vote early and often!
California Audubon has put together a blog post about the Snowy Plover which features a video they just put together. Help us get the word out about protecting the Western Snowy Plover and its habitat! This blog includes many great links, including: National Audubon’s plover page, a video about the Bird of the Year campaign, and dozens more.
We are putting a permanent link to this blog in our Audubon Links section on the right side of the blog. Look for it!

Bolsa Chica Reserve Trip Report: 6 October, 2012
Reddish Egret – Star of the show momentarily motionless (J. Kenney 10/6/12)
The highlights were the shore birds and the biggest raves were for our friends the Reddish Egrets. They were very active, visible and dancing to their own rhythms (or maybe fishing). We were delighted to find an adult molting Black Tern (little guy!). We also had many of the usual birds…. 3 different teal, 3 different grebes, 6 herons/egrets, and a total of 71 different species including the dowitcher sp. (both of which can be found there in abundance and we could not tell which was which). Even the Great Blue Heron posed for us – staring with his great yellow eye. An excellent day for birds and people.
Bolsa Chica Conservancy has a new (2011) checklist that we found most useful.

Progress on the winter ramp tidal clock (J. Kenney 10/10/12)
A Malibu Patch blog of 9 October relates that about one-half of the 70,000 plants have been planted and that California State Parks received a 15-day extension to 31 Oct. to work in the wetland area of the channels in order to finish planting. Dike removal, originally scheduled to begin on 2 Oct. is now planned for 15-17 Oct. They are also hoping for rain, which will benefits the new plants.
View to South Bay across channels & Santa Monica Bay (J. Kenney 10/10/12)
*********************
This video of a Yellow Legged Tinamou by Gustavo Magnago of Linhares in SE Brazil proves three things: this endangered bird still exists, not all tinamous are boringly brown, and this little bird works hard to make his woo-woo call.
Handbook of Birds of the World (1992) reports this species status as “insufficiently known.” Formerly widespread throughout the Atlantic Forest from NE Brazil to NE Argentina, deforestation and hunting has reduced this bird to hanging on at a few sites, of which Linhares is one. In fact, the Atlantic Forest itself – home to several hundred endemic bird species – is vastly reduced.
