Geese, Ducks and Coots, Oh My! Malibu Lagoon, 27 October, 2019

Overwashed beach (C. Bragg 10-27-19)
And we walked ‘till we came to a great big pond,
With the geese and ducks and coots thereon,
‘Twas merry a sight to gaze upon,
And we all had a very fine day-o, day-o, day-o.
It seems that the foxes have given up coop-raiding, become vegetarians and taken up birding.

Greater White-fronted Geese (G. Murayama 10-25-19)
Canada Geese and Brant are by far the most common geese at the lagoon, with 54 and 51 appearances respectively (out of 358 visits). Snow Goose is a distant third with 22 visits, then Ross’s with 14. White-fronted Goose had appeared a mere 6 times and five of those visits (Oct’99 – Feb’00) were likely the same individual spending the winter.

Greater White-fronted Geese (L. Loeher 10-27-19)
So we were surprised and pleased to see these two young birds drifting around the lagoon and channel and resting on the shoreline. The “white front” refers to the forehead. You can see it on the right bird in the first picture, but not on either bird in the second photo, taken two days later. I have no explanation for this peculiarity beyond the usual tricks of light and angle, mussed feathers or the possibility that these birds are not exactly the same individuals.

Check this Great Egret closely (G. Murayama 11-1-19)
A Snow Goose was there as well, although he/she (you can’t tell the sexes apart without a very personal examination) didn’t seem to be interested in the other geese. A few days later there were two Snow Geese, plus a Brant. This young bird’s white plumage is still a bit smudgy, but it has the diagnostic goth-style “black lips.”

Coot and Snow Goose interaction; mutual suspicion? (C. Bragg 10-27-19)
Four Ring-necked Ducks were also present, either females or young males. (Young males look like females for at least several months.) This species much prefers fresh water to brackish or salt water. They can be completely absent from the lagoon all winter, yet be happily paddling around on the two small Pepperdine fresh water ponds less than a mile away. They often winter in small numbers on SoCal inland ponds and reservoirs. We’ve seen them at the lagoon only nine times, and today’s four birds is the record high count. You never see the narrow cinnamon ring around their neck unless they stretch their neck out in good light. Birders tend to call them “ring-billed” because of the easily seen white ring near the tip of the bill. The eyering with a “tear streak” behind is a good field mark for this plumage (i.e. not a male in bright colorful plumage). You can see the white bill-ring beginning to appear near the tip.

Ring-necked Duck, probably a young male (C. Tosdevin 10-27-19)
The last notable water bird was the American Coot. They’re common at the lagoon (325 out of 358 visits or 91% of the time) and they average 89 birds per visit, but the previous record coot count was 410 birds on 9-25-11. Today we had 870. It was hard to locate any of the ducks and geese among all the coots.

We often have Belted Kingfisher wintering at the lagoon, but today we had two, both males. A female with a deformed bill had been spotted earlier in the week. We didn’t see it but Chris Tosdevin got a photo.

Belted Kingfisher with a deformed bill (C. Tosdevin 10-22-19)
Black Turnstones at the lagoon are outnumbered more than 4-to-1 by Ruddy Turnstones (AKA The Turnstone in England), partly because the Blacks vastly prefer rocky shorelines. They always winter on the Ballona jetties. So it’s a minor surprise to see them poking around the sandy and vegetated edges of the lagoon as we did, often accompanied by Ruddys.

Snowy Plovers were in abundance. We counted forty, mostly resting in dents in the sand. We didn’t see any bands, but then we didn’t make them all stand up so we could see their legs.

Gadwall in the distance are a boring gray. The fine vermiculations are visible only when close (L. Loeher 10/27/19)
Here’s a quiz, submitted by Grace Murayama.

It’s about the size of a Corona bottle. What is it? (answer** at bottom)

The 10-year comparison summaries created during the Lagoon Reconfiguration Project period, despite numerous complaints, remain available 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 Chuck Bragg, Femi Faminu, Larry Loeher, Grace Murayama & Chris Tosdevin for their contributions to this month’s checklist. [Chuck Almdale]
**Wilson’s Snipe. Yes, non-birders, there really is an animal called a snipe. They’re very cryptically plumaged and hard to see when they don’t move.

How Computers Work: Encryption & Public Keys | Video
Mia Epner, who works on security for a US national intelligence agency, explains how cryptography allows for the secure transfer of data online. This educational video explains 256 bit encryption, public and private keys, SSL & TLS and HTTPS.
Part VIII (7 minutes) of the series produced by Code.com explaining computers in terms most of us can understand. We’re getting past the ins & outs of downloads and uploads and into the guts. We’ll post a new installment approximately every ten days until we run out.
If you like this series and want to go through it at your own rate, the 17 videos listed HERE include the 12 which I have scheduled so far. Having some familiarity with the topics, I watched the first 12 in about an hour. It’s time well spent.

Unusual Occurrences at Malibu Lagoon
Chris Tosdevin was at the lagoon on Saturday, October 12th and photographed two juvenile Greater White-fronted Geese. In the last 31 years our records show only two sightings, in 1988 and in 1999/2000 (five months in a row of the same bird[s]). So yes, this is a most unusual bird for the lagoon.
Another infrequently seen bird at the lagoon is the Peregrine Falcon. Usually they fly by and scare all the gulls, but they don’t stick around. This one paused to eat an American Coot. The pigeons must have been somewhere else.
Thanks to Chris for these photos and for the documentation.

Hermit Thrust (R. Juncosa)
Several people had signed up for this trip, but only one of those showed up; others were reportedly put off by the lack of parking spaces. In spite of our efforts to avoid it, we managed once again to hit the exact same day of the Boy Scout Jamboree, hence no parking spaces. Fortunately, others did show up, and we had a nice little group of eager birders.

Western Bluebird (R. Juncosa)
The day was lovely, not too hot, and for us from west LA, a welcome lack of smoke. The birds managed to avoid the Boy Scouts, and our list will show a fair number. It includes the usual suspect foreign invaders (not their fault!): Scaly-breasted Munia, in bands of 20 or so, sticking close together cheek by jowl, Bronze Mannikin, a spectacular Pin-tailed Whydah, and several Japanese White-Eyes. The pond was entirely covered by green algae and looked like a lawn, which American Coots, Mallards and American Wigeons were swimming through.

White-faced Ibis (R. Juncosa)
As we spent some time counting Warblers: Yellow, Wilson’s, Orange-crowned, several beautiful Townsend’s and Nashville — a goodly haul — a White-faced Ibis flew by, and then a Red-shouldered Hawk came along with a fresh mouse that he proceeded to have for breakfast.

Red-shouldered Hawk, sans mouse (R. Juncosa)
Several Woodpeckers, mostly Nuttall’s and a few Flickers, knocked on the trees. Tree squirrels importuned us for whatever we might have in our pockets.
At the garden area, we were scolded by a few House Wrens, also California Towhees showed up. We noted sadly that many of the trees we were used to seeing had been taken down: a visiting Audubon Board Member from Orange County told us they were victims of the shot hole borer. We did note also that not only were there Boy Scouts, but many people were in the Park that day, of all ages, particularly young people (complete with cell phones). It was a good place to be that day. [Liz Galton]
