Rerun: The migrating birds of Bear Divide, with Ryan Terrill: Tonight, Weds., 8 June, 7:30 p.m.

June 8, 2022

[Posted by Chuck Almdale]

Ryan Terrill was sick last night and couldn’t give SMBAS his presentation. However, he is scheduled to do it tonight for Los Angeles Audubon, which is a rescheduling of the LAAS program from last month.

Wednesday at 7:30 pm, 8 June. 
Details are here: https://www.laaudubon.org/events/2022/s7sc4ob3326fr9k9qvma2gdqh71kz9-4ytgg-r3pes

Fortunately for SMBAS, Richard Crossley, bird field guide writer and one intimately familiar with Bear Divide and the entire project, had tuned in to watch his friend Ryan. When Ryan didn’t appear, Richard volunteered to speak impromptu about the Bear Divide project and the migration patterns of passerines in general. [Hint: They don’t just fly at night but also look for food in the early morning. Find their food and you’ll find them.] It was very interesting to all. If we recorded it we’ll put it on the blog. I didn’t time it but I’d guess it was 30-45 minutes long.

The Migrating Birds of Bear Divide, with Dr. Ryan Terrill.
Zoom Evening Meeting, Tuesday, 7 June, 7:30 p.m.

Zoom waiting room opens 7:15 p.m.

Bear Divide, in the San Gabriel mountains, has been recently found to host spectacular morning flights of migratory birds in the spring. For the past 4 years, birders have been counting migratory birds at Bear Divide, and over the past two years, the Bear Divide Migration Count has been intensively surveying this location to learn more about this unique phenomenon. Join count organizer Ryan Terrill to hear about this site, what kinds of birds use it, and what has been learned so far about this fantastic bird migration location.

On the lookout.

Dr. Ryan S. Terrill grew up birding in California, and after graduating from U.C. Santa Cruz received his Ph.D. from Louisiana State University, for his study of the evolution of molt strategies in birds. He is a co-author of the Field Guide to the Birds of Bolivia, and the recent description of the Inti Tanager [see below], a new genus and species of bird to science, as well as 24 other publications in peer-reviewed journals. He is active in the academic ornithology and the California birding communities, and has dedicated much of his past 4 springs to surveying morning flight of spring migrant birds at Bear divide.

Pelicans & Phalaropes: Malibu Lagoon, 22 May 2022

May 28, 2022

[By Chuck Almdale]

Look for the mystery bird photo just above the trip list.

Lagoon, beach, pier and cloud fog (Lillian Johnson 5-22-22)

The fog kept the temperature comfortable. Big ones were rolling in at the beach, and the waves were covered with surfers. Outsiders kept appearing, and the surfers were too close in to catch them, always a disappointment for surfers and watchers alike.

Surfers find their way through the stones (L. Johnson 5-22-22)

It’s spring, (pre)-June gloom is here, and our birds are disappearing to the north. A few might be back by late June—Western Snowy Plovers, for example—but June is normally the month for low numbers and low diversity. Today we had only 452 birds in 39 species.

Turkey Vulture (Ray Juncosa 5-22-22)

That seemed a bit low for May, so I decided to check. It turns out that:
10 Mays 2012-2021 low-high range: 262-918 birds, 30-55 species
10 Mays 2012-2021 average: 530 birds, 42 species (rounded)
5/22/22 below the prior 10-year average: 15% birds, 7% species
So…below average but within ‘normal operating parameters,’ to misuse a phrase.

Barn Swallows oft’ were o’er the beach (Chris Tosdevin 5-22-22)

Most notably absent were the sandpipers (‘shorebirds,’ ‘waders,’ ‘peeps’). Two whole birds! (if you exclude the plovers).

During the winter the Spotted Sandpipers are spotless (R. Juncosa 5-22-22)

But one of them was a ‘good’ bird: a female Red-necked Phalarope. We get some of these irregularly during migration, but not many and not often. Here’s a few numbers: Out of 299 census dates, we’ve seen 70 birds total over 19 sightings. Sightings are: 2 in Apr, 3 in May, 1 in July, 7 in Aug, 5 in Sep, 1 in Nov. So August and September are your best bets, followed by May.

Red-necked Phalarope female seen a week earlier (Mel Raab 5-15-22)

There may have been something wrong with this bird. I got an email from Mel Raab who sent me a photo of a female taken on May 15 walking on the pebbled shore (of the lagoon, I believe). When we saw the bird on 5/22, a week later, it looks like it may be the same bird and it’s also walking on the shore.

Left: Brown Pelican [dead] and Red-necked Phalarope. (R. Juncosa 5-22-22)
Right: Red-necked Phalarope a bit closer. (C. Tosdevin 5-22-22)

Two passing birders said they’d seen it in the water earlier. When the bulk of our group laid eyes on it, she was walking up the sand from the water. So it’s not paralyzed or at the edge of death. Just tired, perhaps. Or…a totally different female; two birds, one at a time, a week apart. Yes, these things happen and the birds frequently fail to keep us updated on their plans.

Song Sparrow: eat and sing, sing and eat. Repeat. (L. Flynn + C. Tosdevin 5-22-22)

Phalaropes feed in the water, often by twirling in a circle which creates a little whirlpool that brings up tiny edibles from below which the bird can pick off the surface or close to the surface with it’s very thin bill. I’ve never seen one walk up and down the shore like a Least Sandpiper looking for something to grab.

Pelicans and cormorants (L. Johnson 5-22-22)

Phalaropes are also among the few avian species that are polyandrous—females take more than one mate. Female phalaropes are also more colorful than the males, a situation known as ‘reversed sexual dimorphism;’ ‘reversed’ because when the sexes look different, it’s usually the male that is more colorful. Some polyandrous females mate sequentially, breeding with one male, then traipsing off to find another, then another, and then another if time and weather permits.

Squirrels eating. What do you think that orange thing is; – a cocktail wiener?
(L. Flynn 5-22-22 & G. Murayama 5-26-22)

Other polyandrous females mate with several males at the same time. Some of the Jacana species do it this way. I haven’t been able to find out how many bird species in the world are polyandrous. When I wrote a 3-part article about polyandry and reversed sexual dimorphism six years ago, I discussed 17 polyandrous species, but found mention of about 40 polyandrous species in total—not many (0.37%) out of 10,800 species of birds.

Caspian Terns: head, shoulders & tail above Elegant Terns.
Not really; it’s an optical illusion. (R. Juncosa 5-22-22)

Most of the gulls have left, and the tern population dropped significantly as well. The Double-crested Cormorants were sitting on the stones in the lagoon, the Pelagic Cormorants were swimming in the near-surf zone, and the 50 Brandt’s Cormorants were a fly-by flock.

Brown Pelicans, flying (Lynzie Flynn 5-22-22)

There has been a drop in the local population of whatever fish the Brown Pelicans like to eat. Some of them are starving to death, literally, and we saw perhaps six pelican corpses on the edges of the lagoon and on the beach. One such corpse was in close proximity to the sleeping Red-necked Phalarope.

Brown Pelican, awake (G. Murayama 5-26-22)
Brown Pelican, asleep (G. Murayama 5-26-22)
Brown Pelican, dead (G. Murayama 5-26-22)

Once again we did not—as expected—see any Western Snowy Plovers. They’re just not here this time of year, unless a pair decides to mate and nest here. But oftentimes a few birds have returned by the time of the June trip, back from breeding somewhere farther north.

The often heard but rarely seen Wrentit appeared briefly at ‘picnic corner.’
(L. Flynn 5-22-22)

Birds new for the season: Brant, Red-necked Phalarope, Common Raven.

Heermann’s Gull 2nd year. All the adults have gone to nest
at Isla Rasa in the Sea of Cortez. (G. Murayama 5-26-22)

Malibu Lagoon on eBird as of 5-28-22: 5842 lists, 313 species

Male Gadwall. Gadwalls and Mallards will probably nest
at the lagoon again this year. (R. Juncosa 5-22-22)

Many thanks to photographers: Lynzie Floyd, Lillian Johnson, Grace Murayama, Mel Raab, Chris Tosdevin

Low tide, fog out to sea (L. Johnson 5-22-22)

Upcoming SMBAS scheduled field trips: Our next trip will be Malibu Lagoon on June 26. This, and any other trip we announce will—for the foreseeable future—be dependent upon the expected status of the Covid pandemic at trip time. Any trip announced may be canceled shortly before trip date if it seems necessary. By now any other comments about this topic should be superfluous.

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, if desired, with parents and small children.

Not a bird commonly seen at Malibu Lagoon. What is it? (Mel Raab 5-15-22)

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 Lynzie Floyd, Lillian Johnson, Chris Lord, Grace Murayama, Mel Raab, 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 with the California Bird Records Committee Official California Checklist, updated 15 Jan 2022. I generally do this sequence update at the start of each year.

New Birding Guide to the Greater Pasadena Area | Pasadena Audubon Society

May 15, 2022

[Posted by Chuck Almdale]

I’m a big fan of birding guide books. In lieu of a paid guide and a whole lot cheaper, they can get you to the right places to find birds, rather than driving aimlessly around crashing into things while looking around for birds instead of watching the road. Not all good birding spots can be easily found on the web, not all web sites give you succinct directions and descriptions, and not all areas have great web reception. A book in hand is worth two on the web. Or maybe four. Our neighbor chapter Pasadena Audubon Society (PAS) lives in a birdy area where the migrants pass through in aerial rivers, with valleys and rivers and parks and reservoirs and mountain forests and meadows. A book to birding this area would be very useful to residents and visitors alike, and voilà! now one exists.

According to one local birder: “I just bought a copy yesterday at the California Botanical Garden in Claremont and did not realize it was hot off the press. Quite a bit pricier ($35) at the garden than online ($20).”

If you’re a die-hard “if it’s not on the web it doesn’t exist” person, here’s a link to SMBAS’ on-line bird-finding guide for Los Angeles County with 81 sites spread over seven pages. It’s getting a bit out-of-date.


Here’s the PAS message:

Pasadena Audubon is pleased to announce the publication of their all-new Birding Guide to the Greater Pasadena Area. The Guide gives detailed descriptions of 30 of the region’s top birding hotspots, along with background on the area’s ecology, seasonal species distribution charts, birdability access ratings of the locations, profiles of the notable introduced species, and much more.

For more info about the book, as well as a list of stores in the Pasadena/Los Angeles area that stock the book, visit https://www.pasadenaaudubon.org/birding-guide .

The Guide is also available online from Buteo Books, at https://www.buteobooks.com/mm5/merchant.mvc?Screen=PROD&Product_Code=15274 .
