New Blog Page on Malibu Lagoon Reconfiguration

June 19, 2012

We’ve created a new permanent page on our blog devoted mostly to photos of the reconfiguration project, now underway.
It’s self-explanatory. https://smbasblog.wordpress.com/malibu-lagoon-project/
There is a permanent link to this page on our blog home page, located under the title photo.

Link to a large archive of USGS lectures on film, such as the 3/31/11 lecture by Jon Hagstrum on How Homing Pigeons Know Where To Go. It is fascinating and presents a strong case that sound is the major clue to the birds rather than sight, magnetic field, etc.

Full Strawberry Moon 6/4/12 4:12 a.m. PDT

June 2, 2012
by

Here’s another update from SMBAS Blog on that large shining object which has frequently and mysteriously appeared in our nighttime sky this year (known to many as the moon).

June 4, 4:12 a.m. PDT — Full Strawberry Moon.    Known to every Algonquin tribe, Europeans called it the Rose Moon.   A partial eclipse of the moon will be visible chiefly favoring those living around the Pacific Rim.   Observers in Japan and Australia for instance, can see it at, or soon after, moonrise, while those in the western United States and western Canada see it at, or just before, moonset.    At maximum, about 37 percent of the moon’s diameter will be immersed in the dark umbra shadow of the Earth.

The next significant full moon will occur on July 3, 11:52 a.m. PDT.   Keep an eye on this spot for additional breaking news on this unprecedented event.

This information comes to you courtesy of:

Solstice Canyon Trip Report: 5/12/12

June 1, 2012

This slideshow requires JavaScript.


We had a great attendance of eighteen people, including some students from Cindy’s birding class.   People in the parking lot were greeted by a Red-tailed Hawk sitting in one of the trees, as well as a puffed-out Olive-sided Flycatcher.

Olive-sided Flycatcher displaying his ‘tufts’ for all to see (J. Kenney 5/12/12)

At the entrance to the trail, there was a tree with a nest of Nuttall’s Woodpeckers.   Everyone got a good look because the parents were feeding them often.   Later on we stood and watched a Common Raven gathering nesting material.   We kept waiting to see where it was nesting and finally the bird landed at the site but it was not visible like the Nuttall’s nest.   All along the trail, Black-headed Grosbeaks were serenading us but it was some time before anyone saw one of them.   Later, at the granary tree we saw just a few Acorn Woodpeckers.

Yellow-breasted Chat – not easy to find in western L.A. County (J. Kenney 5/12/12)

The area was not as active with families of woodpeckers as we are used to seeing.   Sound-wise, besides the Black-headed Grosbeaks, we could hear the Hutton’s Vireo, Pacific-slope Flycatcher, Lesser Goldfinch, and Purple Finch and could find all of the birds except the Purple Finch.   Chuck Almdale called the Canyon Wren in but it took a lot of coaxing to get it to quit hiding behind the leaves.   Finally we could see a silhouette as it stood on a snag one third of the way up the slope.   It really gave us a chance to see how the long bill is.   On the horizon there was another Red-tailed Hawk and a Turkey Vulture.   Our trip was also a good day for hummingbirds since we found 3 species: Allen’s, Anna’s, & Black-chinned.

California Wild Rose in magnificent bloom (J. Kenney 5/12/12)

The flowers were quite good for a year that was short on rain.   This walk always offers a chance to compare the Bush Sunflower we see along the roadside (brown center) and the canyon sunflower (yellow center) which likes a little more protection.   This year the Deer Weed seemed to have formed larger and very good looking bushes whereas the Hummingbird Sage was much more modest from the lack of rain.  [Jean Garrett]

Malibu Lagoon Trip Report: 27 May, 2012

May 31, 2012

This slideshow requires JavaScript.


This is our last lagoon trip report before the scheduled start of the reconfiguration process, so we made a few changes to our usual trip report format.  We’ve put a bunch of scenery shots in, and the bird list compares the months of May across the past six years.  We’ll follow this format until after the project is

North channel view to west towards golf course (L. Johnson 5/27/12)

done; the data should be useful to compare during-project months to prior years.  I keep my count numbers as honest as I can; there’s never any attempt to jack any number up or down.  My obvious and mostly worthless prediction:  count totals and species diversification will drop during the project, then rebound.  No prediction how much the change will be.  This is like J.P. Morgan’s stock market prediction: “The market will fluctuate.”

The slideshow shows what the area looked like this day, excepting Jim Kenney’s February scenic photo.  The lagoon outlet closed within the past 7 days:, lagoon water level had risen so much that Snowy Plover enclosure fenceposts I’d stood next to 8 days earlier were now partially submerged.

Whimbrel on low tide rocks (J. Kenney 5/27/12)

The birds were pretty much what we’d expect for late May: a few migrant shorebirds (Whimbrel, Black-bellied Plover); some nesting birds (Mallard, Black Phoebe, Barn & Cliff Swallow, Northern Mockingbird, House Finch).  The egrets are developing a large heronry next to Starbuck’s in the shopping center: Great Blue Heron, Great Egret, Snowy Egret and Black-crowned Night Heron are all nesting there.  15 Heermann’s Gulls had arrived from their breeding grounds on islands near the southern tip of Baja California; they were all 1st-year birds.  One Belted Kingfisher perched on dead branches in front of Adamson House.  We found a pair of Black Phoebes feeding 4 fledglings near the Adamson Boat House, as well as a female Mallard with 5 fluffy ducklings.  No project activity is scheduled for this side of the lagoon.  We didn’t see the young Killdeer spotted a month ago: it’ll be full-sized and flying by now, but it won’t yet have adult plumage.

View from beach across lagoon (L. Plauzoles 5/27/12)

Our next three field trips:   Mt. Piños Birds & Butterflies, June 16/17, 8 am;   Malibu Lagoon, 24 June, 8:30 am;   Malibu Lagoon, 22 July, 8:30 am.
Our next program: Tuesday, 2 October, 7:30 pm.   The usual reminders will be emailed from the blog.
Picnic:  The usual June chapter picnic is canceled.

NOTE: Our 10 a.m. Parent’s & Kids Birdwalk is canceled until the lagoon project is completed and the parking lot is again available.

Prior checklists: July-Dec’11, Jan-June’11, July-Dec ’10Jan-June ’10, Jul-Dec ‘09, and Jan-June ‘09.

Comments on list below:  Of 75 total species appearing in May for 2007-12, no more than 62% of them have appeared on any one day, something to keep in mind if you wonder why what is there is much less than what could be there.  Species low of 39 in 2010 is 17% below the highs of 47 for 2007, 2008 & 2012, not a huge drop.  Total birds low of 413 in 2011 is 66% (787 birds) below the high of 1200 in 2007.  Species making up most of this difference: Brown Pelicans – 549, Western Gulls – 109 and Heermann’s Gull  – 61 (total of 719 birds, 91% of total difference).
NOTE: Right column averages of less than 1 bird/month are shown in tenths; all other averages are rounded to nearest whole number.   [Chuck Almdale]
