Spring Migration & Plumage Changes: Malibu Lagoon, 24 April 2022

May 4, 2022

[By Chuck Almdale]

A gracefulness of Elegant Terns (Lynzie Flynn 4-24-22)

Springtime is definitely here. It was very breezy; at least 5 mph with gusts to 20. “We’re probably not going to see a lot of passerines today…it’s tough to see birds moving through moving leaves.” The variety of passerine species—17—turned out to be higher than I expected, but total passerine count of 64 was only 60% of our average over 25 years of April count days.

The temperature started at 72°F at 8:30 am, a bad place to start, as it can end well (not well) into the 80° by 11:30. We were lucky and it was only 75° when we stopped, although the breeze had died by then. Warm, but not hot. Quite pleasant, in fact, with a clear blue sky. Another you-know-what day in paradise.

We changed the attendance format slightly this month. We still took reservations, raising it from 25 to 30, and the trip was sold out due to the low, low cost of admission (because we pass the savings on to you!), although there are always a few no-shows. Lu Plauzoles was again the co-leader, and this time he came equipped with a microphone connected to a small speaker near his solar plexus. “Saves my voice,” he said, the sound issuing disconcertingly from his stomach instead of his mouth, like some sort of ventriloquist. “Otherwise, I’ll be croaking by eleven.” It looked odd but worked well.

I don’t know what changes—if any—we’ll make for the May 22 field trip. Look for a trip announcement with details around May 10, and a go/no go announcement two days prior to the trip.

We had a few avian surprises. The coot population had dropped from 65 last month to one whole bird, but we had six waterfowl species, with Gadwalls amounting to half of the totals. There were eleven species of sandpiper and plover, more than I expected. I also hoped for an oriole, whether Bullock’s or Hooded, but none appeared nor announced their presence.

Does the forward leg of the middle bird look weird to you?

It was really nice to see an Eared Grebe in breeding (alternate) plumage. You can see their ears, for instance, those bushy reddish-brown feather-sprays sprouting from behind their eyes. Most of the time when they’re here they’re in their basic (non-breeding) plumage, but sometimes, just before they leave for the north, they grace us with their finery.

Semipalmated Plovers are passing through again, this time on their way north. April is their most reliable month. I looked at the past 12 years and if we’re there (I missed two Aprils), they’re there. I strongly suspect that they’re there in April whether or not we’re there to observe them. [Take that!, Schrödinger wave function collapse fans!] Fifteen birds is a good count for this species, but by no means their highest.

The other unexpected sighting was six Spotted Sandpipers. All had spots, unlike the fall and winter birds which are inconveniently spotless. We usually have 1-3 birds spend the whole winter at the lagoon, but not this year; we hadn’t seen one since last August and September. We never have many: the highest count for 168 sighting-days was ten birds on 25 Oct 2015, but we usually have one or two prowling the edge of the lagoon during non-breeding season. The first one we saw (see left bird below) was happily resting on top of a large boulder among the low-tide-exposed rocky tidepools in front of Malibu Colony. I don’t think I’ve ever seen one on the ocean side of the beach before; they really prefer the edges of the lagoon and channels, or even inland of the PCH bridge along the edge of the creek.

Unlike Western and Least Sandpipers (and the occasional Dunlin and Red-necked Stint), they don’t freely associate with other species of small sandpipers (aka ‘Peeps’), and just barely associate with other Spotted Sandpipers. When we have 2-4 at the lagoon, a typical number range, they’re all in different places, not hanging out with each other. This is reminiscent of the very-well-named Solitary Sandpiper. I’ve never seen more than one ‘Solitary’ at a time, anywhere, ever. Perhaps they reproduce by parthenogenesis, or budding off clones of themselves like coral polyps.

Water was lowish in the lagoon; the tidal sidewalk clock was completely dry and mud-free, and the west end of the channels was dry mud.

Song Sparrows were singing from the brush in numerous locations. We managed to spot a few. White-crowned Sparrows—unlike Song Sparrows—don’t nest at the lagoon, and have mostly fled. California Towhees were calling. Two male Brown-headed Cowbirds were present; we didn’t see any females. This prompted me to give the group a brief discussion of Cowbirds, Buffalo-birds, Cuckoos and nest parasitism. Fascinating stuff (cue eye-roll).

Tidepooling up & down: Whimbrel & Marbled Godwit (Lynzie Flynn 4-24-22)

Killdeer are probably nesting somewhere on the beach or sandy islands, but we didn’t see any signs of them. Double-crested Cormorants are also up their old tricks with sticks and strands of kelp streaming from their bills, from the beach to their several nesting trees in the shopping center.

The big prize (Double-crested Cormorants (Lynzie Flynn 4-24-22)

There was one group of ten Bushtits, which may still be hanging on as a group since last fall, or may be the result of several new families already fledged and prowling the bushes together. We couldn’t see them well enough to try and tell if they were a mixture of adult and fledglings.

We looked and looked but found no Western Snowy Plovers. Presumably they have all left for their usual nesting grounds farther north. Five days earlier, on 19 April, Grace & Larry had only one WSP at Malibu Lagoon and none at all at Zuma.

Upcoming SMBAS scheduled field trips: We may do this again on May 22, depending on the oncoming Omikron Ba.2…whateva infection wave. Watch for blog announcements.  Reservations will be taken starting May 10. Limit 30 people by reservation only, vaccine card, bring your own equipment. No 10am Children & Parents walk. Maybe we will have some other, different trips if anyone is interested.
Watch the blog for announcements AND for cancellation by 20 May if warranted. Same deal for 26 June lagoon trip; June 10 and 24 will be announcement dates.

The next SMBAS program: Bird Migration at the Bear Divide, San Gabriel Mtns., with Ryan Terrill of Occidental College. Zoom Evening Meeting, Tuesday, 7 June 2022, 7:30 p.m.

The SMBAS 10 a.m. Parent’s & Kids Birdwalk remains canceled until further notice due to the near-impossibility of maintained proper masked social distancing with parents and small children.

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 Lillian Johnson, Chris Tosdevin and others for their contributions to this month’s checklist.

The list below now includes a column on the left side with numbers 1-9, keyed to the nine categories of birds at the bottom. The species are re-sequenced to agree to the California Bird Records Committee Official California Checklist, updated 15 Jan 2022. I generally do this sequence update at the start of each year.
