SANTA MONICA BAY AUDUBON SOCIETY BLOG

It seemed like a good time for a test to see if field trips were feasible.

To maximize safety and compliance with local laws, I set rules: SMBAS board members only, masks and social distancing required, bring your own scope. A group of seven gathered, and off we went.

Overall it went fairly well. But we were a small group of civic-minded birders, and the only infraction was one person who couldn’t keep their proboscis covered. No rants, no foaming at the mouth, no summer soldier shouts of “Give me liberty, or give me death! Unmasked I arrived into this world, unmasked I shall take my leave!”

A question arose. Where does the heron’s neck go when flying?

Adrian, our physician/anatomist-in-residence, replied: “To begin with, the heron’s cervical vertebrae (that’s the neck bones) have a unique structure allowing them to hinge over an adjacent vertebra. That is why they have that curious kink in the neck and how they can strike so swiftly to catch prey. This enables them to fold their necks in an”S” shape, hence they can lengthen or shorten the neck.”

I thought it just telescoped down into it’s torso, like a tripod leg, or perhaps the neck inverted itself like a snake swallowing its tail from the inside, or it compressed and stretched like the hose of a vacuum cleaner, or it Möbius-stripped itself into a parallel dimension, but then I don’t have the medical degrees requisite for this exacting a physiological analysis.

Lillian and I had arrived early, and while checking the parking lot area, found a group of seven – SEVEN! – Hooded Orioles, moving through the sycamore trees. We’ve seen Hooded Orioles many times before at the lagoon, as they’ve nested there for years in various trees, both deciduous and palm. We’ve seen both adults, year-old birds and juveniles. But rarely this many, all at the same time. Later perusal of A Guide to the Nests, Eggs and Nestlings of North American Birds, Baicich & Harrison, 1991, told me the following:

Begin nesting early April to early May. Two or sometimes 3 broods. Usually four eggs, sometimes 3-5. Eggs are long subelliptical to long oval. Smooth and glossy. Very pale blue, sometimes with a slight pink or purple wash. Finely scribbled and scrawled or with a few elongated blotches or specks of black, usually with the markings concentrated at the larger end. Sometimes almost unmarked. 22 X 15 mm. Eggs laid at daily intervals. Incubation by female alone. 13 days. Nestlings are altricial and downy. Down sparse; on head and back. Young tended by both parents. Leave nest at 14 days.

So this could have been a single family group – two adults and five young, from a recent hatching. But I thought one or two of the birds looked a bit older than recently-fledged. So perhaps it was a second hatching and one or two young from an earlier hatching accompanied the new group. Sort of an extended family. But the latter possibility is just conjecture.

Back home, I checked my spreadsheet and found that we’ve sighted Hooded Orioles at the lagoon 36 times with a total of 85 birds, including this sighting. Our all-time high count was eight on 7/22/01, followed by six on 7/24/11. Most of the sightings were of undoubtedly the same individuals in consecutive summer months, such as the one to four birds sighted over five months, 4/24/19 – 8/28/19.

We were certainly not the only people at the lagoon and on the beach. Perhaps half, probably less, were masked. Social distancing was practiced, generally, except for what appeared to be a surfing class for kids; they were shoulder-to-shoulder and unmasked on the sand, including their accompanying adults. Surfers, of course, keep their gear to a minimum and avoid masks. Once they’re on the waves, this seems sensible, but less so while they walk to the beach on the often-crowded path.

Birding while masked is not great. If it’s only you or your family unit, you can skip the mask when the contagious and obviously rabid “others” are not near. But in a group such as ours, with people clustered and milling about, you have to keep the mask on nearly all the time. I found that for at least the first hour, when temperatures were cool, my binocular eyepieces would fog up within seconds and I was constantly wiping them. After too many wipes, I just stepped farther away from the group and pulled down my mask when I wanted to stare at a bird. That solved the fogging problem. By the time we reached the beach, the day had warmed and fogging while masked didn’t seem to be as much a problem.

So if you go a-birding in a mask, keep your microfiber lens cloth close at hand, and maybe a handkerchief as well to sop up excess moisture.

The Canada Geese were still there, all eight of them, two adults and six near-full-size young. They were resting near a group of gulls, shorebirds and Western Snowy Plovers on the beach near the east side of the lagoon, the area right above the log full of Double-crested Cormorants in the photo below. I don’t think any of them moved a muscle the entire time we were nearby, admiring the shorebirds and checking the eight plovers for leg bands (none found).

Birding was pretty good, but then after months of infrequent-to-never birding, it was nice just to get out in the sun and breeze and watch a few feathered friends flinging themselves about.

As usual more than half the birds were gulls and terns, primarily Western Gulls and Elegant Terns. The latter were there in all plumage stages, from begging juveniles with stubby pale yellow bills to fully decked-out  adults. Same goes for the Western Gulls, our most local gull, as many of them nest on Acacapa Island, about forty miles away, along with the Brown Pelicans.

This is the time of year the Heermann’s Gulls return from their nesting grounds on Isla Rasa in the middle of the Sea of Cortez, a tiny uninhabited island where about 95% of the world’s Heermann’s Gulls and Elegant Terns nest. We generally get them in all plumages, but in recent years there have been massive breeding failures due to lack of proper sized prey fish. So it’s nice to see juveniles.

There doesn’t have to be a “bird of the day” but it’s nice when there is. We were staring at the outer rocks near the Malibu Colony of humans.

Adrian alerted me to it. “I think there’s a small bird out there.”
Me: “There are small knobs on those rocks which look just like birds. Sure it’s not one of those?”
“I think it’s a bird, not a rock.”
“Which rock is in on?”
“The big rock, on top, about in the middle.”
Scanning, then finding. “Hey, it really is a bird!…Jumping Jehoshaphat, I think it’s a Wandering Tattler! That’s a good bird for here. They like rocks, not sand, so we don’t get many.”
Someone asked, “Aren’t they down at Marina del Rey, on the jetties?”
“Yeah, but they’re not terrifically common even there. You’re always lucky to find one.”

So we admired the bird as best we could. A couple of hundred yards away, only 11” long, mostly gray, on a gray-brown rock, above a blue-gray sea and against a cloudy gray sky. I’ve seen tattlers only seven times at the lagoon, the first on 11/17/19, each one a solitary bird.

You may have noticed that some of the photos, taken by Grace Murayama, have a different date. Grace and Larry regularly census the Snowy Plovers and Least Terns (if any) at both Malibu Lagoon and Zuma Beach. They couldn’t join us, so I included some of her photos from other dates. Here’s another.

Western Snowy Plovers, Sanderlings and Western Sandpipers often roost together on the beach. They’re all small birds with predators, for whom the more eyes the better, and they don’t compete with each other (well, a little, maybe) when searching for food. So they get along about as well as might be expected.

Birds new for the season: Pied-billed Grebe, Anna’s Hummingbird, Snowy Plover, Ruddy Turnstone, Least Sandpiper, Long-billed Dowitcher, Wandering Tattler, California Gull, Elegant Tern, California Scrub-Jay, Wrentit, Hooded Oriole, Red-winged Blackbird. [Some of these species may have been present in March & April, but we weren’t there to see.]

Many thanks to photographers: Adrian Douglas, Lillian Johnson, Grace Murayama.

Our next three scheduled field trips: Who knows? Not I.
Our next program: We may carry something on Zoom near the end of August. Watch for announcements.
NOTE: Our 10 a.m. Parent’s & Kids Birdwalk is canceled until further notice due to the near-impossibility of maintaining proper masked social distancing with parents and small children.

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.
