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.

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]

Malibu Lagoon Field Trip Report: 24 April, 2011

April 25, 2011

It’s still unseasonably cold. Most of us never got our jackets off, and a breeze of 5-8 mph made it feel chillier. I know, I know, I shouldn’t be complaining about temperatures in the high 60’s when people are freezing in Mongolia or fighting tyranny house-to-house in Libya, Yemen, Sudan, Ivory Coast, Liberia, and on and on. But if you can’t complain about the weather, what else is there to complain about? Politics? Why, everything in politics is perfect, in this best of all possible worlds.

The peculiarity of the day was the enormous number of Brown Pelicans. I counted 740, an all-time high, but there could easily have been many more, as they kept coming and going in droves. Here are all the prior counts over 200:

315 5/22/05, 400 3/26/06, 230 4/22/07, 630 5/27/07, 239 6/24/07, 320 3/23/08, 231 5/25/08, 256 1/25/09, 205 6/27/10, 740 4/24/11.

And here are the past six Aprils:
79 – 2005, 47 – 2006, 230 – 2007, 35 – 2008, 78 – 2009, 182 – 2010, 740 – 2011

The only pattern I see is that this is an all-time high, which we already knew, and that the numbers bounce around a lot, although usually below 100 for April. A number of passersby asked us if we knew why there were so many. One person thought there had been some sort of general nesting failure on the local Channel Islands (primarily Anacapa), possibly due to lack of food. Another had heard that the pelicans were sensitive to the vast amounts of radiation pouring out of the damaged Fukushima Daiichi nuclear reactor and had fled Japan and across the Pacific Ocean to safety in California. The PQ* of that explanation seemed quite high to me, not least for the fact than none of the world’s eight (some say seven) species of pelicans regularly occur in Japan. (This is a waffling way of saying they just aren’t there.) We here at SMBAS Central Command don’t know why all these pelicans showed up, and a few minutes searching Google didn’t turn up any answers or even any mentions. Anyone out there know anything?        * – PQ – Preposterosity Quotient

The total species count at 55 seemed a bit low for April, so I checked and for the past eleven years, we’ve averaged 59 species in April, with a low of 52 and a high of 70.

Cryptic Killdeer eggs (C. Almdale 4/24/11)

Out on the beach inland of the (now deserted) Snowy Plover enclosure, we startled a Killdeer, who proceeded to stagger and flop off with what appeared to be a broken wing. As most birders should know, this is a distraction display the adult puts on to lure a potential predator away from its nest. Lu quickly found the nest about 10 ft away from where we stood. I took a few pictures and then we dutifully followed the adult away so it could win this skirmish. Hopefully no crow or gull was paying attention and the nest remains safe among the sticks and pebbles.

Adult Killdeer lures me to water's edge and continues to keep an eye on me (C.Almdale 4/24/11)

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

Where do birders go when they are not out birding on their home turf ? Some go to other parts of their own country to see birds. Some go to other continents to see exotic birds and completely different countries and peoples. Ghana certainly qualifies as different from Southern California; it has its unique birds and it is in Western Africa, a far part of the world .
I went to Ghana which is fascinating, hot, humid, colorful and near the Equator. We spent most of the trip in our “coaster” van/bus on the road driving to places to see birds who were sometimes seen and sometimes not. In Kakum National Park, home of a rather scary canopy walk from tree to tree over a hundred feet in the air, we saw two elephants and wonderful Hornbills. In the north of Ghana (near Bolgatanga) we saw donkey carts, in the south near the coast we saw bicycles and motor bikes. In the north we saw mosques and mud villages and town pumps. In the south we saw evangelical churches and more mud villages and town pumps. I think we were on every major road in the country (I would hesitate to call them highways as few had more than two lanes – one each way) and we visited most of the National Parks in the country. But one of the favorite things of the trip was reading the sayings on the back of the taxis and buses and the names on the stalls lining streets. Most of these were in the Christian south and the exuberant imagination was very evident. A few favorites:
God Loves Furniture
Kindness and Mercies Catering
King of Glory Bakery
Christ is the Almighty Plumbing Works
Merciful God Vulcanization
God is Able Consultancy
Oh My God (on the back of a bus – considering the accidents)
No Money No Honey (on a vendor’s t-shirt selling….)
Secret of My Joy is Jesus Printing & Photography
Only God Knows Hair Dying
God’s Way Special Rice
Fingers of God Phone Shops
Naked I Came Water Co.
… and my favorite..
With God All Things Are Possible Cosmetics Shop
and there were so many more.
We did see hundreds of birds as well and many of them new. Hooray. One of my favorite birds was the Woodland Kingfisher which darted in front of me in a flash of blue, snapped up a hapless lizard and was last seen whacking it on a tree branch with great abandon. Go nature !
