Malibu Lagoon Field Trip Report, 22 May, 2011

May 30, 2011

Despite the oft-predicted and much-vaunted “End of the World” and/or “Day of Judgment”, Saturday, May 21 was no more noteworthy than usual for a Saturday in May, or for a Day of Judgment, for that matter. I think there’s been several dozen such days in the past 150 years, and so far…well, I hope none of you were surprised or disappointed by the lack of events. My absence caused a momentary riffle of consternation that I’d been raptured, an unlikely event under any scenario, but actually we were at the Grand Canyon, which is close enough to rapture for me. We saw a condor there, #246, very low overhead, much to our delight.

As a result, on Sunday, May 22, the coast was clear for some good ol’ Malibu Lagoon birding, led by the able and energetic Lucian, who supplied this report. Fourteen friendly people attended including a few new faces. Apparently Spring migration is almost complete, with few seasonal birds in attendance. The general species count was low, as were the number of beach people. There weren’t even many surfers. The outlet is currently a well-behaved stream, exiting far to the east near the lifeguard tower closest to the pier, but not endangering the riprap wall of the Adamson House. The beach berm is vegetated mostly with Sea Rocket and the sand mound is high and at least 100 feet deep. The Snowy Plover virtual fencing has been removed and – as last month – we saw no Snowies.

Brown Pelican adult and sub-adult (C.Almdale)

Gull count was extremely low; the Brown Pelicans were down to a more typical number. The most surprising sighting, surprisingly enough, was 7 Great-tailed Grackles. This species has been present at the lagoon 65 times since they first showed up in April 1995 and, except for 25 birds on 8/27/06, we’ve never seen more than 6 at a time. [OK, OK, 1 more than 6 doesn’t amount to much more, I admit.]

After birding the marsh and the beach for about two hours, a few hardy souls drive up to the Pepperdine reclamation ponds, but no new species were found.

As a reminder to those who plan to come to our 10 a.m. Parent’s & Kids birdwalk, they meet at the beach trail footbridge closest to the parking lot.

Field Trip Report: Solstice Canyon, 7 May, 2011

May 15, 2011

The lovely riparian environment of Solstice Canyon greeted us with the Canyon Sunflower, California Towhees, Spotted Towhees, Wrentits, and this time, several Orange-crowned Warblers.  Each one of these species offered their own variety of the trill.  It either became confusing or the repetition helped people learn to distinguish the songs.

With the Canyon Sunflower (yellow center) on the moist side and the Bush Sunflower (brown center) on the dry side of the trail we could easily separate the two species.

Bush Sunflower (C.Almdale 5/11)

Canyon Sunflower - abundant this year (C.Almdale 5/11)

Margaret Huffman reminded us that there are only 3 rivers in the Santa Monica Mountains that have water during the Summer, and Solstice is one of them (Cold Creek & Malibu Creek are the others). Near the river we saw and heard a lot of Lesser Goldfinches and Pacific-slope Flycatchers. I didn’t realize that the California Bay trees need to be near the water which is why we see so many of them at Solstice.

When we made the big right turn to go up to the house, the Sycamore tree at the corner was still being used as a granary by the Acorn Woodpeckers.

Female Nuttall's Woodpecker at nest-hole (J.Kenney 5/11)

A little further up the trail we found the nests of an Acorn family and a Nuttall’s Woodpecker family.  The last fire occurred in 2007 and it looks like the trees that died are just right for woodpeckers.  Perhaps we can look forward to more nests.  Along the slope towards the house, we could see Purple Sage, Black Sage and one White Sage and we managed to see Red-tailed Hawks & a Northern Flicker.  The racket from the Black-hooded Parakeets was deafening but we were rewarded with the sighting of two Mitred Parakeets among the group.

Canyon Wren singing downstream of burned house (C.Bragg 5/11)

**** **** A Canyon Wren responded to our tape and perched in the branches of a dead tree for quite a while.  We got the 4 most likely Hummingbirds: Anna’s, Allen’s, Costa’s, & Black-chinned.  Common Yellowthroats, Black Phoebes, Bushtits, Dark-eyed Juncos, Song Sparrows, Bewick’s Wrens, Western Scrub Jays, Black-headed Grosbeaks all made their appearances.  The House Wrens serenaded us all the way up the slope.  At the top where the house is we saw the Hooded Orioles among the palms and heard another Canyon Wren.  The surprises were: Brown Pelican (a lot of them are being seen this year along our coast), California Thrasher (which I wish we could count on more often), White-breasted Nuthatch, Red-shouldered Hawk, and Phainopepla.  On our way back, we could hear the Purple Finch but it took a long time to spot it in the granary Sycamore.  We did see some Crows, Ravens, a Starling, an unknown empidonax flycatcher, and a Brown-headed Cowbird.

The butterflies must have felt it was not warm enough because we hardly saw any today but the flowers were great.  The yellow Bush Monkey-Flowers were growing in large patches and we got a first in this canyon: the Fringed Indian Pink.   [Jean Garrett]

Mitered Parakeet (C.Bragg 5/11)

Parakeets: We were about 5 minutes walk below the burned house when a pair of Black-hooded Parakeets flew by, loudly squawking. I squawked back at them and – surprisingly – they lit in a nearby dead bush. We squawked some more and two more flew in and landed. These parakeets (all parakeets have long pointed tails) had red faces so they were something different. One had a bit of red on the forehead (see photo); on the other the red spread from the crown to behind the eye and below the bill. They both had prominent white eyerings, large pale bills, irregularly scattered red flecks on their head, neck and shoulders, but no visible red at bend of wing, tail or “leggings”. The more red-faced bird looked like Red-masked Parakeet, while the pictured bird looked more like Mitered. Both species are in the general  Malibu-Pt. Dumé area (as is Red-Crowned Parrot) although I had not seen either here before. Further research at home – confirmed by Kimball Garrett – convinced me they were both Mitered Parakeets, which are variable in the amount of red they show, the result of both age (less red on younger birds) and individual variation. If either were Red-masked, we should have seen red at the bend of the wing. [Chuck Almdale]

“Bicolored” Blackbird found at Malibu Lagoon

May 4, 2011

Bicolored Blackbird - note lack of yellow margin on epaulets (J.Kenney 4/11)

A few years back, while watching either a Red-winged or Tricolored Blackbird (getting old, don’t remember which), I made a personal discovery. Until then, I had always assumed that the yellow or white “margin” on the red epaulets was the terminal end of the mostly red feather. This bird was in full display; it erected its epaulets to the maximum, I could see right to the base of the feathers, I saw that the “margin” was actually a separate set of feathers lying below the red epaulet feathers, and these sub-epaulet feathers were completely white (or yellow) right to where they grew from the skin.

Bicolored Blackbird - subspecies or accidental aberration of Red-winged? (J.Kenney 4/11)

These pictures were taken by local photographer James Kenney on 4/30/11 about 8 a.m, at the 2nd footbridge on the path to the beach. So far as I know at this time, it’s the first appearance of the Bicolored Blackbird at the lagoon, and it may well be its southernmost sighting. Dan Cooper commented on the pictures, “I can’t remember seeing one down here, though it’s a common form up in central California to the Bay Area, and probably occurs rarely throughout populations.” He also passed on a Wikipedia citation written by central Californian bird maven Alvaro Jaramillo: “There are a number of subspecies, some of doubtful status, which are  mostly quite similar in appearance, but the ‘Bicolored Blackbird’ A. p. gubernator of California and central Mexico is distinctive. The male lacks the yellow wing patch of the nominate race, and the female is much darker than the female nominate. The taxonomy of this form is little understood.” Commenting on Alvaro’s citation, Dan added, “I can’t imagine that a race occurs as disjunct in both coastal California and central Mexico (and not in between), so it may be, as I suspect, a normal/relatively common variation – like the yellow house finch, that simply”pops up” here and there across the huge range of the species.” I concur with Dan, but I wonder whether the margin feathers in the Bicolored are merely shortened or are completely absent. If anyone knows, drop me a line or post a reply here. I found an interesting article on the web but – lacking sufficient academic credentials – could get access to only the first page: The Status of the California Bi-colored Blackbird, Joseph Mailliard, The Condor (Cooper Ornithological Union), March 1910.  If anyone can send this article to me, I’d greatly appreciate it and will report what (if anything) I discover.

These pictures and comments have been added to our Unusual Birds at Malibu Lagoon page (aka Lagoon Birds).  [Chuck Almdale]

Pelicans and other Birds in the News

April 28, 2011

In our blog on the Malibu Lagoon 4/24/11 field trip, we noted that there were 740 Brown Pelicans resting at the lagoon. This was 110 more than our previous high count of 630 on 5/27/07, but we didn’t know why so many were there. This phenomenon is larger than the lagoon, and others are wondering as well.   [Chuck Almdale]
