Not that I’m complaining, but the weather seems weird to me. Does it to you? When the 24^th of May ranged from 59-70° and the 25^th of January was 73-81°, well…that’s just plain weird. They must be screwing around with our weather. Again. Whoever they are. Probably the same they as in “They tried to tell us we’re too young, too young to really be in love…” You know. Them.

Rampant paranoia aside, I prefer cool summers. Bring on the fog! Let it linger until November. Those nattering nabobs of nitwitism who reside in the howling wildernesses east of the Colorado River claim we have no seasons here. Sorry folks; we do have seasons. Roughly equivalent to Spring, Summer, Fall, and Winter are: Fog, Smog, Fire, and Mudslide. Recently, Mudslide season dwindles while Fire expands. ¡Qué lástima!

It always seems odd when lots of birders appear at the lagoon in May and June as, bird-wise, those are the two slowest months. “Don’t be disappointed,” I say, “but it’ll be sparse. Come back September through March, and there’ll be many, many more.” But now, the wintering birds have left, most migrants have passed through, many of our local nesters are concealed, sitting cryptic and quietly on well-hidden nests, or skulking about, trying not to be captured and consumed.

On the lawn at Adamson House we found a foraging Northern Mockingbird. Not an uncommon sight, in itself. But it was frequently flicking its wings as it walked along the

ground. We didn’t know if this was a foraging behavior, an anxiety/startle behavior, or a display of sexual attractive or aggression. A little research showed that this is a long-debated topic. One paper (Hailman, Wilson Bulletin, Dec 1960) concluded it was primarily a foraging technique, intended to startle insects into movement. Others aren’t so sure, ‘unease’ or alarm being a possibility, as is aggression. All 14 species (4 or 5, depending on who’s talking, in the Galapagos alone) of mockingbirds do this, whether or not they have white wing-panels as do our Northern Mockingbirds. They also flap and leap while singing.

Apropos of nothing whatsoever, here’s a nice hour-long video/soundtrack of birdsong and babbling creek, good for listening to while researching mockingbird behavior.

We had 590 birds in 48 species, down from last month’s 6009 birds in 53 species, a difference of 5419 birds. 98.4% of that decline was due to the drop in 4 species: Brown Pelican, Heermann’s Gull, Western Gull, Elegant Tern. [See the trip lists below.]

Western Gull in repose (R. Ehler 5/24/15)

These birds are all off nesting – or should be, if they know what’s good for them. The Heermann’s, for example, begin laying eggs in late April at their eight known nesting areas; 95% of the species’ 150,000 pairs nest on Isla Rasa, located about halfway down the Sea of Cortez. At the same time, this tiny island also hosts over 90% of the world’s 40,000 pairs of Elegant Terns. It’s a busy, noisy, stinky place this time of year. But changes in weather, sea currents and sea temperatures cause massive changes in availability of food fish. The Elegant Terns may have suffered a complete nesting failure this year on Isla Rasa due to lack of food.

Brown Pelicans, et. al., discover a small school of fish (R. Ehler 5/24/15)

Many of the Gadwalls looked like young birds – not ducklings, full size but not in adult plumage. Perhaps they are the result of early nesting near the lagoon? We didn’t see any warblers – not a single Yellowthroat – but the Song Sparrows sang up a storm, various swallow species made off with mouthfuls of mud to build nests on nearby walls, and hummingbirds, particularly the Allen’s, were almost abundant on Adamson House’s flowered wall. A couple of cormorants staggered around the lagoon-edge with sticks in their mouth, and across the street, the top of the recently shaved nesting tree next to Starbuck’s was adorned with egrets and their nests.

There were even orioles: at least three Hooded Orioles – two females and one yellow-not orange year-old male – were in the trees near the Colony wall. Hooded Orioles – the ‘hood’

Hooded Oriole, one year old male (R. Ehler 5/24/15)

is yellow in the female and orange in the male – always nest in palm trees. Look on the underside of palm fronds for their light brown pendulous nests, suspended near the central frond shaft, woven of thin fibers from palm leaf and trunk. Adult males have a large black ‘bib’ on their throat. Also around, but not seen today, are deciduous-tree-nesting Bullock’s Orioles; orange & black males have black crowns and small black chin patches; the yellowish females have white bellies, unlike the female Hooded which are all-yellow underneath.

Snowy Plovers, absent since January, remained absent, which is normal for May.

House Finches take a bath at Adamson House (R. Ehler 5/24/15)

Birds new for the season were: Pacific Loon, Red-tailed Hawk, Spotted Towhee, Red-winged Blackbird, Brewer’s Blackbird, Hooded Oriole. We finally got over to Adamson House but saw no additional species. The House Finches were busily bathing, so we beat a hasty retreat.

Our next three scheduled field trips:  Mt. Piños Birds & Butterflies, 13-14 June, 8am; Malibu Lagoon & Picnic, 28 June, 8:30 & 10am; Malibu Lagoon, 26 July, 8:30 & 10am.

Our next program: Evening meetings will resume on Tuesday, 6 October, 7:30 pm, at [changed again] Chris Reed Park, 1133 7th St., NE corner of 7th and Wilshire Blvd. in Santa Monica.

NOTE: Our 10 a.m. Parent’s & Kids Birdwalk meets at the shaded viewing area. Watch for Willie the Weasel. He’ll be watching for you.

Even at the meeting spot the air was filled with the screeching of terns. Flights of Brown Pelicans constantly cruised by, and clouds of terns regularly lifted from the distant beach, only to alight again upon the sand. This promised to be an unusual day.

Finally! An Osprey on the osprey pole (R.Ehlers 4/26/15)

Passerines (songbirds) were few on the ground. Early-arriving photographer Randy Ehlers (thanks for all the great pictures, Randy!) spotted 40 Cedar Waxwings, who were living up to their ‘betcha-can’t-see-just-one’ reputation. No warblers, few sparrows and little of anything else beyond the usual Black Phoebe, Mockingbird, California Towhee and House Finch. Various Swallows have arrived, but not in large numbers.

From the lookout point near the PCH bridge, the terns – save a few Caspian and Forster’s – turned out to all be Elegant. And they looked very elegant as long-time member Abigail King liked to say, with bright white bodies, long forked tails, black crests and legs, and colorful bills ranging from pale yellow through orange to medium red. People often ask if the bill color of Elegant Terns is useful for identification. The short answer is: when comparing the Elegant bill to the Royal bill, look at shape, ignore color.

At any rate, there were a boodle – maybe two boodles – of Elegant Terns; I counted 3100. This took a while. They were busy with mating, chasing, flying, feeding and always, always screeching. Some had breasts faintly pink from their oil glands. We did find a few more Caspian and Forster’s among them, and some Royal Terns far out on the exposed shore rocks. And it was a great chance to see the varieties of Elegant bill color.

Back home, I checked for previous highs counts for Elegant Tern and Brown Pelican.
Brown Pelican: 1490 (4/26/15), 740 (4/24/11), 630 (5/27/07), 407 (7/24/11), 400 (3/26/06)
Elegant Tern: 3100 (4/26/15), 700 (4/26/09), 600 (7/28/13), 300 (7/25/04), 250 (4/27/03)
Definitely a phenomena of migration.

I asked Kimball Garrett, ‘skin man’ at the Natural History of L.A. County Ornithology Dept., if anything weird was happening with the terns and pelicans. He relates: the Brown Pelican 2014 nesting season in the Sea of Cortez failed almost completely; no info yet on 2015.  Warm SoCal coastal water this year may reduce Channel Island nesting. Our Malibu flock may be a  mix of failed breeders from Mexico and our Channel Islands. Elegant Tern nesting on Isla Raza in the Sea of Cortez apparently failed completely this year; as in recent past years, the southern California colonies seem to shift around as predators cause abandonment.

Snowy Plovers have been mysteriously absent since January. Populations at other L.A. County winter roosting sites, including nearby Zuma Beach have also been affected, says Stacey Vigallon, L.A. County Snowy Plover maven. She didn’t know why, either.

Birds new for the season were: Brant, Eared Grebe, Semipalmated Plover, Dunlin, Least & Western Sandpipers, Caspian & Forster’s Terns, Belted Kingfisher, Cliff Swallow, Cedar Waxwing. We didn’t get over to Adamson House as the lagoon outlet cut through the beach and by the time I finished counting all those pelicans, gulls and terns, I too was finished.

Our next three scheduled field trips:  Morongo Valley & Black Rock Cyn, 2-3 May, 8am; Malibu Lagoon, 24 May, 8:30 & 10am; Mt. Piños Birds & Butterflies, TBA (probably 13-14 June, 8am.)

Our next program: Tuesday, 5 May, 7:30 pm. Icelandic Birding, presented by Joyce & Doug Waterman. PLEASE NOTE THAT WE NOW MEET AT DOUGLAS PARK, 2439 WILSHIRE BLVD.
