Driftwooded beach at Malibu Lagoon, 25 Feb. 2024
[Text by Chuck Almdale; photos by Ray Juncosa, Larry Loeher & Grace Murayama]

Partly cloudy, as you can see, temperatures mostly in the high 50s with a slight breeze. The sea was about as flat as it can get; only four people in the water, vainly waiting for a wave. Waveless winter days means a depopulated beach. The lagoon channel to the sea had moved well to the east, next to Adamson House; the wide rushing icy cold stream kept beachwalkers from wandering westward from the pier.
Near our meeting spot under the metal pavilion – I can’t come up with a better name – a few ducks and coots paddled around the channels and a miscellany of sandpipers were on the sand. Several Killdeer were screaming bloody murder for reasons known only to themselves. The cormorant-of-the-day, pictured below, assigned snag duty, looked quite frosted, from what I don’t know. Perhaps the cold lagoon water.

Some of the cormorants have developed their bushy white eyebrow-crests of breeding, but not the one above. If you look closely at the Great Blue Heron below, you can see his (or her) chestnut shoulder-patch and chestnut legs.

Canada Geese have nested at the lagoon for at least the past three years. They appreciate the brushy sand islands, as people never wade out to them. There were nine in the lagoon and channels, checking everything out.

The Lesser Goldfinches were numerous and noisy, feeding on seed heads. This male has developed his black cap.

Looking west from the path to the beach, just north of Malibu Colony, as in the photo below, you can see the red roofs and white stone bell tower of Pepperdine University at the far left.

We had a lot of Brown Pelicans in all stages of plumage. Photographer Ray Juncosa became fascinated by their landing, flapping and bill-poking. Most of them were offshore just past the surf-(less) zone, but about 60 were in the lagoon, the channels, and on the low rocks after the water level dropped towards the 4pm low tide.






The brown ones are the immatures. The adults get colorful creamy-yellow and brown heads and necks, red gular pouches and silvery backs.
When waves aren’t crashing over them, the outer rocks often have cormorants, a seal and the occasional Black Oystercatcher. This is the best place to find either Brandt’s or Pelagic Cormorants. These two species hate to venture inland, and crossing the beach all the way to the lagoon is simply too far for them to chance the journey. If you don’t see them on the rocks, they may be in the water somewhere in the vicinity of the surf zone, paddling around, diving for fish.


The beach from lagoon-edge to shore, from the colony to lagoon outlet, was covered with driftwood, shells – mostly mussel – and seaweed. I can’t recall ever seeing so much flotsam and jetsam on this portion of the beach.

Towards the lagoon edge and among the chunks of wood were 21 roosting Snowy Plovers, out of the breeze and nearly out of sight. Among them were scattered a few Sanderlings, a common roost-mate of Snowy Plovers.

We’d seen 18 Snowies in October, only one in November, and none at all in December and January. They’d probably been on the east shore, hiding within the driftwood piled up on the east side until the recent storm shifted everything around.

The 10-year comparison summaries created during the Lagoon Reconfiguration Project period, remain available—despite numerous complaints—on our Lagoon Project Bird Census Page. Very briefly summarized, the results unexpectedly indicate that avian species diversification and numbers improved slightly during the restoration period June’12-June’14.
Many thanks to Marie Barnidge-McIntyre, Femi Faminu, Lillian Johnson and others for their contributions to this month’s checklist.
The species lists below is irregularly re-sequenced to agree with the California Bird Records Committee Official California Checklist.

Tom Gauld on the journey to a magma chamber | New Scientist

If you subscribe to New Scientist, you can read the whole story below. Otherwise it seems to peter out after a few interesting paragraphs.
World’s first tunnel to a magma chamber could unleash unlimited energy
New Scientist | Graham Lawton | 3 Jan 2023

Lead paragraph:
ICELAND is one of the most boring countries in the world. That is meant as a compliment, not an insult. The island nation is dotted with thousands of boreholes drilled deep into the rock to extract geothermal energy. They will soon be joined by another, which will be anything but boring. “We are going to drill into a magma chamber,” says Hjalti Páll Ingólfsson at the Geothermal Research Cluster (GEORG) in Reykjavík. “It’s the first journey to the centre of the Earth,” says his colleague Björn Þór Guðmundsson.
What Bone is This?
[Text & photos by Chuck Almdale]
I don’t know much about bones and certainly not about sea mammal bones. If anyone out there can I.D. this bone and point me towards an on-line source that can illustrate it, I’d be very grateful and will certainly give you credit.

We found the bone in question on Malibu Surfrider beach yesterday. By “we” I mean one of our group of birders came up and handed it to me, asking if I knew what it was. I should mention that the beach was almost completely covered from end-to-end and from high tide line to lagoon with driftwood, seaweed and shells, flotsam and jetsam from the recent storms. I quickly and confidently analyzed the bone as “probably marine mammal…I suppose” thereby exhausting my limited knowledge/guesswork. We wondered if it might be a fossil as it felt so rock solid. But I doubt that. I don’t think a real fossilized-into-rock bone would look like this.
It’s a fragment missing one end. What’s left is 8″ long and weighs just under 9 oz. or 250 grams. It feels very heavy and solid. The surfaces and edges are very worn and smooth.
View 1 (above) and 2 (below) show what looks to me like a socket at the near end of the bone, at bottom, about 1.25 inch across, the same diameter as the hole down the center of the bone.

View 3 below shows the other side of the bone with what looks like a wide groove about 0.5″ across and 2″ long, eroded along the left edge and smoothed on the right edge.

Below: another view (#4) of the end & side with socket showing as in views 1 & 2.

Another view (#5 below) of the flip side like view #3 except that the wide groove is now at the right end.

Below, the “groove” side again. The widest part is 2.5″ from bottom of groove directly vertical (i.e. not along the groove but straight up).

I googled around on-line and found an animated view of a harbor seal skeleton assembling itself. The whole film is interesting and very nicely produced, although the bones could be a little more accurately shaped, and not generic puffy bones. At time 3:35 you get to the left scapula (shoulder blade) and the left foreleg showing the humerus, radius and ulna. After watching the entire film, I returned to the left ulna as the most likely bone, although I wouldn’t call it a perfect match. Perhaps it’s a different species of seal or sea lion, although harbor seal is (I believe) the most common pinniped in the Malibu area.
The film then moves on to the right foreleg, then at time 4:50 moves on to the hips and rear legs including the femur, tibia and fibula. It’s possibly a tibia.
Below: Close up of the interior showing structural ridges.

I tried to find another site showing pinniped or whale bones in detail, but believe it or not, found nothing useful. Nothing! Even those sites claiming “I.D. your bone here!!!!” Nil, nada, zippo.
Below, the groove end showing small pits from heavy wear/erosion?

So…at least one of you osteologists out there, tell us what it is. Please.
Spring Bird Photos | Birds & Blooms
[Posted by Chuck Almdale]
‘Tis the season to see spring birds, fa la la la la….
Well…almost.
Birds & Blooms Magazine has a lot of bird pictures online. Here’s a link to some of their portfolios. Here’s another link to what you’ll see if you merely google Spectacular Pictures of Spring Birds Birds and Blooms.
The pictures below are from their portfolio The 51 Best Spring Bird Pictures Ever.
I recently mentioned partially leucistic birds in a blog, and that I’d once seen a leucistic American Robin. Here’s another, photo’d in Waukesha, WI. “When I saw an American robin with leucism (partial albinism) last fall, I was absolutely enchanted. Winter passed, and I wasn’t sure if I would see this special bird again. I was so happy when it reappeared in my yard once March arrived. This robin is a great photo subject and seems to enjoy posing for the camera!”

Here’s an example of a different coloration problem, photo’d at a feeder in Newport, NY. Believed to be “…an American goldfinch that has normal carotenoid pigments (producing the bright yellow) but is lacking melanins. That’s why it looks as if someone took a normal goldfinch and then deleted all the black from its wings and tail.”

There are 49 more excellent photos in this album which are not devoted to odd plumages, despite appearances to the contrary. I just happened to pick out these two. Then there are loads of other albums with photos like this.

There’s a lot of very good nature photography going on out there. I ran across these photos because a reader sent me a link:
13 Spectacular Pictures of Spring Birds: Bird activity abounds as the season of renewal arrives
Read in Birds & Blooms: https://apple.news/A3jo9h2ChTviQ2uZ5SeD2IQ
But I don’t have an Apple so I couldn’t access the article. Maybe you can. The photos were really stunning.
