Muscovy sex notes
When the mood strikes a male Muscovy duck, the corkscrew-shaped embodiment of its excitement shoots to a fully extended 8-plus inches in just 0.36 second.   The corresponding female organ is also corkscrewed – but in the opposite direction.

Two Puffin Live Cameras on Seal Island
Take a virtual trip to Seal Island–20 miles off the coast of Maine–where Audubon�s VP of Seabird Restoration, Steve Kress, and his team are successfully restoring Atlantic Puffin breeding colonies. Watch these captivating birds as they socialize and catch some rays along with Razorbills, Black Guillemots and more, on the Loafing Ledge cam:

The Puffin Burrow cam takes you down into a rocky burrow, where dutiful parents are caring for a newly hatched chick. Thanks to infrared technology, you can check in on the family around the clock:

Lagoon Project Visit 6/29/12

July 2, 2012
by

Artist’s perspective of west channels view from SW corner (RestoreMalibuLagoon . com)

Nearly a month has passed since the project started, and the changes are significant.   Vegetation and footbridges are gone except where birds (Mallards and a Black Phoebe) are nesting.  The big scoops are removing the top layer of fill dirt which Calif. DOT/Cal Trans began dumping in the 1920/30’s, and trucks are taking it to the Calabasas dump.     The soil beneith the fill is being sculpted to create the elevated  islands.   Nearly completed is the berm separating the channels from the main lagoon.  Contouring of what will be the new channels is beginning.

Despite the noise and the activity, several coots and mallards came in from the main lagoon and paddled around in the water in what’s left of the middle channel.   They ignored us as we passed.

Two coots in middle channel water (L. Johnson 6/29/12)

Mark Abramson had invited me to view the project up close; Lillian and Jim Kenney came as well and Suzanne Goode from State Parks joined us.   [Jim has been quite busy taking photos of the project;  see them on our continually updated special lagoon project page.]   We spent about 90 minutes walking around and talking.   We hadn’t seen Suzanne or Mark in years. since the last lagoon meeting we’d simultaneously attended.

The main lagoon, the Adamson House side, and the beach are not part of the project.   After the few remaining birds in the channels area are finished nesting, the rest of the fill dirt layer will be removed and hauled off.   The underlying original soil will be contoured to look as in the drawing above.   This drawing depicts the channels when the water level is at 5.5 feet, the height of the highest tides of the year.   We’re trying to get a map which shows the planned gradations in detail and will add it here if we do.

The tops of the four islands will remain above water level, even at the highest level of 9 feet which can occur when the beach outlet is closed and water has flowed all summer.   At this level, most of the long peninsula will be covered, permitting channel water to be wind-blown to the east.   The mouth of the main channel will be about 120 feet wide, far larger than any of the current channels, ensuring maximum circulation and minimizing stagnant pools.  There will be no intentional narrowing of any of the channels.  The three footbridges, as lovely and popular as they were, were narrow ‘pinch-points’, restricting water flow and helping to create the stagnant, anoxic pools devoid of life which in turn prevented invertebrates from flourishing in the mud.

Native pickleweeds and other salt-tolerant plants will be widely planted.   With luck and the passage of a few years, we might see the return of the Belding’s race of Savannah Sparrow, a pickleweed obligate which used to live there until a few decades ago.   Before the grading began, seed and plants were collected for propagation by a nursery in Santa Barbara.   This nursery helped in the re-vegetation of some of the Channel Islands.

The berm will occasionally be used as beach path during the project (J. Kenney 6/29/12)

The berm and the long yellow plastic sheeting keeps the lagoon water from getting into the channels.   However, ground water seeps into the channels area and is expected to continue doing so throughout the project.   The berm will be occasionally serve as the path to the beach when work must be done on the current perimeter path.   Many viewing features will be created along the perimeter path.   [Mark explains these in detail in his YouTube video.]

All work in the channels is scheduled to be finished by October 16.   Some peripheral work – re-vegetation, viewing platforms, benches, picnic tables and the like – may take a bit longer.   The new channels will be much more gradually sloped, creating a far larger intertidal zone.  This is the sort of habitat which substrate invertebrates prefer, not to mention the birds that eat them.

One cool idea is a path which doubles as a water level indicator called the Summer Clock – Winter Platform.   I can’t describe how it works so we’ll just have to wait and see.

A problem arose when a governmental employee in some nameless far-off land made a map of Snowy Plover winter roosts locations.   He got it wrong at the lagoon, placing it right where the the south channel mouth passes the large brushy mound of fill dirt, several hundred yards (approximately) WNW of where the plovers actually roost, which is out on the beach on the inland slope of the berm.  Presumably everyone is aware of this error, but until the correction moves through official channels, work can’t start in the erroneous plover area.

Speaking of plovers,  alert reader Kevin Anderson’s blog comment of 6/18 clued us to the fact that project guards were walking through the Snowy Plover virtual enclosure on the beach.  I passed this info on to Mark and several State Parks personnel and everyone has been told to stay out of the enclosure.   However, people being…well, people…don’t be shocked to see “official”-looking personnel wander into it.  So stay alert and send me a message if you see anyone doing this.   In fact, feel free to politely inform such people that they are not supposed to be in there, whomever they are.   The sole exception to this are the people (me, for example) who census the plovers, look for banded birds or adjust the fence.

The planning and approval for this project began so long ago and it was so difficult getting the funding, that I – among many – never thought it would actually happen.  When people asked me about it, my response for many years was a dry,  “Yeah…I’ll believe it when I see it.”   Well, seeing is believing, so believe it.   The more I see what’s going to be done, the more excited I get.   Once it’s finished, when the walkways are done, the viewpoints are done, the plants are growing and spreading, the water starts moving and the birds begin finding food in the channel mud and using the islands, I’m sure you’ll like it.

Full Buck Moon 7/3/12 11:52 a.m. PDT

July 1, 2012
by

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

July 3, 11:52 a.m. PDT — Full Buck Moon.   This full moon was so called because it occurs when the new antlers of buck deer push out from their foreheads in coatings of velvety fur.   It was also often called the Full Thunder Moon, thunderstorms being most frequent at this time. Sometimes this is also called the Full Hay Moon.   Since the moon arrives at apogee less than 13 hours later, this will also be smallest full moon of 2012.   In terms of apparent size, it will appear 12 percent smaller than the full moon of Jan. 10.

The next significant full moon will occur on Aug. 1, 4:27 p.m. PDT.   Keep an eye on this spot for additional breaking news on this unprecedented event.

This information comes to you courtesy of:

But that’s waaaay too long to type in, and besides, you don’t need to go there because SMBAS has done the work for you!
