From Canyonlands NP Facebook page: “View from the Maze: A pair of Bewick’s Wrens makes a nest in the brain cavity of an old bull’s skull. Where bovine ruminations once roamed a quick feathered flickering now prevails. If your skull ended up in a tree what species of bird would you like your brain cavity to host? (GC)”
Years ago in the Salt Lake Valley my sister Annette had a home on Wren Road.
One day she and a friend watched birds scurrying all over the property, plucking nesting materials. “I wonder what kind of birds those are,” my sister said.
“Did you ever wonder why they named it ‘Wren Road?’” her friend replied.
If you want your bird watching friends to think you’re experienced at it, remember Bewick’s, as in “Bewick’s wren,” is pronounced like the automobile, “Buick’s.”
Our goldfinches left several weeks ago. The cedar waxwings came through in at least three big waves, starting in February (and the last just over a week ago). House finches moulted, and the breeding males have bright red heads. Migrating robins left us by the end of January, but a lot more residents stayed with us.
We have at least one, and maybe three cardinal families. A black-capped chickadee family stuck around. Haven’t seen a titmouse in a month, but I think they’re still in the neighborhood. The black-chinned hummingbird family is back, and maybe a few other hummers. The resident blue jays and white-winged doves duke it out every day. Carolina wren stayed, and may have already fledged; but there are too many wrens for one family — is that a Bewick’s wren?
What’s THAT?

It’s a rose-breasted grosbeak, Pheucticus ludovicianus. It seems late for migrating birds, but only because so many migratory species migrate earlier these days.
Haunts of the rose-breasted grosbeak, from Cornell University’s ornithological laboratory.
Would love to have a grosbeak family, but the Cornell ornithologists say this is fly-through territory. Maybe that explains why it won’t scare by the white-winged dove,Zenaida asiatica. Dallas is the western edge of the grosbeaks’ migratory path, but the eastern edge of the dove’s territory. They probably don’t see much of each other.
No, he’s not particularly gold — but this is winter, and if he’s going to get his breeding plumage, it will come in a couple of weeks.
We’ve had Niger thistle seed feeders out for years; this year one goldfinch (Spinus tristis) finally started to visit. We’ve had as many as four at a time — but they’re probably headed north soon.
Here’s a shot of our first guest, from a couple of weeks ago.
A goldfinch male, checking out the feeder before bringing in his buddies — we hope.
If you’re north of Dallas, and you see this guy at your feeder this summer, tell him “hello” from us.
The non-breeding plumage isn’t so flashy as the bright yellow of the breeding males. Some of the finches settle in to a beautiful, smooth olive-drab livery for much of the winter. Close up, they look like good pen-ink-drawings by a master artist.
The white dove was a short-lived interlude; the white-winged doves seem to be with us constantly.
One family in 2011; two families in 2012 — and our yard isn’t that big.
A very early version of the birds who visited, befriended, and plagued Snoopy — this drawing, while faithful to Shultz’s work, was done by another artist.
Earlier this week I looked out, and it looked like the early “Peanuts” comic strip when Snoopy opened his dog house to a group of pigeon-like birds for their poker game. The birds took advantage of Snoopy’s largesse, and nearly over-ran him. (Woodstock was a product of that flock of birds, the last remaining vestige by Charles Shultz‘s death.)
At least they didn’t drink our beer and try to make off with the Picasso.
White-winged doves are really too big for any of our feeders — but what are you going to tell a rampaging herd of them? Photos by Ed Darrell – use encouraged with attribution.
Enough doves to frighten Alfred Hitchcock — Two of these birds is too many for either side of this feeding station. How many do you see here?
Not enough room for all, and so they jostle and push each other off the feeders. See the display of the white stripe on the wings of one of our subjects here, from which the species gets its name.
Blue jays enforce the “too-long-or-too-many-at-the-feeder” rules here, but they can be distracted by peanuts put out by neighbors. In any case, they were absent when we needed them.
We used to have mourning doves, but at some point in the last five years this bunch pushed them out. We may be the only ones on the block who noticed. (Yes, it’s “mourning” dove; Duncanville’s having misspelled it on “Morning Dove Lane” is their error.)
It was last April. Kathryn’s garden near the patio needed some work, and of course there are all the plants in pots, including the orange tree (which has since been joined by a pomegranate).
Birds visit often — we hang three or four birdfeeders. Cardinals, house finches, the Carolina wren and her family, and a lot of white-winged doves commonly hang around.
Of a sudden a flutter of wings — and there he was:
Where did this dove come from? For a few weeks in the spring, it haunted our yard.
We assumed it was male, but we have no way of knowing for sure. At one point it seemed to make mating advances on some of the white-winged doves — but who knows.
The bird followed Kathryn around. It ignored the feeders farther out in the yard, and concentrated on the feeders on the patio. Then it would land on our patio table and watch.
Sometimes it splashed in the birdbaths.
The bird appeared at ease around people. It would watch us work or play in the back yard.
Difficult to miss — the white was positively glowing. When it flew in, it’s path suggested it came from a house up the alley a ways. Was it a refugee from some cote, an escapee? Or was it a trained bird just out for exercise?
A few times it arrived in the morning, and hung around for an hour or two. Its usual pattern was to arrive in the early evening, grab a few seeds, do a lot of watching, and disappear.
With its color, we feared it would be a target for hawks.
Where it flew to roost, we couldn’t determine.
One day it flew off, and didn’t return.
The mystery dove. Where did it come from, was it tame? Why was it here? Where did it go?
I’ve been calling these guys Bewick’s wrens (Thryomanes bewickii) for a couple of years, based on an identification I made a couple of years ago — but checking today to be sure, I’m thinking this is a Carolina wren (Thryothorus ludovicianus) instead.
In any case, a couple of days ago it paused for a few minutes in our backyard rose arbor, long enough I could try to get a good shot with just a 200mm telephoto, and with colors dulled by the window.

Bewick’s wrens probably have more grey on their bellies; this one looks ruddy enough to be a Carolina wren. (I just learned “Bewick’s” is pronounced like “Buicks.”)
Wrens stick around all winter now; they didn’t just over a decade ago. This family has been with us for at least three years — two young this year successfully fledged. By now it’s almost impossible to tell which are the young, which the parents.

On our patio we have a saga continuing with Gulf fritillary butterflies (Agraulis vanillae), their larva, and passion vine. It seems our neighbors eradicated passion vine, so when the frits start moving north in the spring, they find our passion vines as the only ones in town. The females go nuts laying eggs, and at some point we have a surplus of larva who denude the vines in a week. Late hatching larva probably die off.
The butterfly books suggest that we cull the larva, but we don’t have the heart. At some point in the spring the wrens wake up to the issue, and they cull the larva for us. The vines recover, a new wave of frits hatch out, and the cycle begins again. From June through September, the passion vine loses any leaves it puts out within 48 hours, usually. But the wrens probably eat well.
The wrens seem never to perch where we can see them when they sing. I suspect these little guys of having a much better voice than most wrens, but the great arpeggios I hear may be another bird, perhaps a warbler, that I just don’t know (good reason to go spend time at the local DogwoodCanyon Audubon Center, yes?).
Understanding the physics of the Earth’s atmosphere poses great problems — it is an astonishingly dynamic, fluid environment. Understanding the relationships between species in ecosystems is no less complex, and no less vexing.
Wise followers of science recognize that when findings in biology, chemistry and physics, point the same direction, something powerful creates the convergence, and is not to be ignored.
So it is with these findings from the University of Montana and the U.S. Geological Survey, demonstrating clear links between climate change and the changing life patterns of large animals like elk, small animals like birds, and the plants the animals live in and consume. This study is so complex that climate denialists haven’t figured out which part to deny, yet. (This press release came out in January.)

Dramatic Links Found Between Climate Change, Elk, Plants, and Birds

Missoula, MT – Climate change in the form of reduced snowfall in mountains is causing powerful and cascading shifts in mountainous plant and bird communities through the increased ability of elk to stay at high elevations over winter and consume plants, according to a groundbreaking study in Nature Climate Change.

The U.S. Geological Survey and University of Montana study not only showed that the abundance of deciduous trees and their associated songbirds in mountainous Arizona have declined over the last 22 years as snowpack has declined, but it also experimentally demonstrated that declining snowfall indirectly affects plants and birds by enabling more winter browsing by elk. Increased winter browsing by elk results in trickle-down ecological effects such as lowering the quality of habitat for songbirds.
The authors, USGS Montana Cooperative Wildlife Research Unit scientist Thomas Martin and University of Montana scientist John Maron, mimicked the effects of more snow on limiting the ability of elk to browse on plants by excluding the animals from large, fenced areas. They compared bird and plant communities in these exclusion areas with nearby similar areas where elk had access, and found that, over the six years of the study, multi-decadal declines in plant and songbird populations were reversed in the areas where elk were prohibited from browsing.

“This study illustrates that profound impacts of climate change on ecosystems arise over a time span of but two decades through unexplored feedbacks,” explained USGS director Marcia McNutt. “The significance lies in the fact that humans and our economy are at the end of the same chain of cascading consequences.”
The study demonstrates a classic ecological cascade, added Martin. For example, he said, from an elk’s perspective, less snow means an increased ability to freely browse on woody plants in winter in areas where they would not be inclined to forage in previous times due to high snowpack. Increased overwinter browsing led to a decline in deciduous trees, which reduced the number of birds that chose the habitat and increased predation on nests of those birds that did choose the habitat.

“This study demonstrates that the indirect effects of climate on plant communities may be just as important as the effects of climate-change-induced mismatches between migrating birds and food abundance because plants, including trees, provide the habitat birds need to survive,” Martin said.
The study, Climate impacts on bird and plant communities from altered animal-plant interactions, was published online on Jan. 8 in the journal Nature Climate Change.

Imagine for a moment that you are a wee little mousie, sitting on a tuft of grass nibbling on a seed. You think you feel a breath of a breeze from in back of you and you turn around to see this beautiful thing
Owls fly silently. Their feathers have evolved to move without rustles, to let the wind slip through them without making a whish. Owls demonstrate evolution at its mightiest, and nature, as the poets note, “red in tooth and claw.”
I’d like to know more about this film. Trained owl? Wild owl enticed by what kind of bait? Longer movie about eagle owls? I’m not familiar with them. So many little mysteries on the internet.

From Wikipedia
The Eurasian Eagle-owl (Bubo bubo) is a species of eagle owl resident in much of Europe and Asia. It is also one of the largest types of owls.
* * * * * *
The Eagle Owl is a large and powerful bird, smaller than the Golden Eagle but larger than the Snowy Owl. It is sometimes referred to as the world’s largest owl, but this is actually the Blakiston’s Fish Owl, which is slightly bigger on average.[2][3] The Eagle Owl has a wingspan of 138–200 cm (55–79 in) and measures 58–75 cm (23–30 in) long. Females weigh 1.75-4.5 kg (3.9-10 lbs) and males weigh 1.5-3.2 kg (3.3-7 lbs).[4][5][6] In comparison, the Barn Owl weighs about 500 grams (1.1 lbs).
One of the most frequent hoax charges against Rachel Carson claims that she didn’t base Silent Spring on research. Greater hoaxers claim that there is little or no evidence of harm to birds from DDT.
Rachel Carson's book stirred controversy, as shown in newspaper headlines
These critics forget history, or they try to cover it up so you won’t know any better. Carson provided more than 50 pages of citations to peer-reviewed research and communications with leading scientists in ornithology and chemistry about DDT and the damage it does.
Paul told the birders that Interior was proud of the fact that so much of the research in the book relied on Interior’s research, from the U.S. Fish and Wildlife Service:
In addition, we are proud that so much of ‘Silent Spring“ is based on Fish and Wildlife Service research. And, with no modesty at all, we like to point out that Miss Carson is nobly carrying on a tradition that employees of the Department of the Interior, beginning with Walt Whitman nearly a century ago, have written some of the Nation’s most important books.
That’s quite the compliment to Carson, being compared even distantly to Walt Whitman. It’s also a helluva brag for USFWS.
It’s also a 30-second response to the false charge that Carson’s work was not research based, or that research did not show DDT damage to wildlife.
Paul spoke to the Audubon Society about work to set up and operate the Federal Pest Control Board.
Terri Potts Smith showed up bright and early for work — was it in the spring? — and we talked in our first floor Dirksen Senate Office Building office about the grind we faced ahead with the hearing schedule for the Senate Labor Committee and subcommittees. Suddenly she was transfixed by something out the window.
Having just recently learned that terrorists favored that particular corner for planting bombs under cars, I started a bit. Terri explained, astonished, that a red bird flew into the tree out the window.
It was a cardinal (Cardinalis cardinalis), a common bird, but not one common to Utah, where both of us had grown up.
I think of that often these days, and am still constantly startled, to see green birds flit across the streets of Duncanville, Texas.
Monk parakeets. Myiopsitta monachus. Also known as the Quaker parrot.
Monk parakeets profiled in the Chinese pistache, Duncanville, Texas, August 10, 2010 - photo by Ed Darrell; more than a dozen birds are hidden deeper in the tree.
Monk parakeets are invasive in Texas — it is thought the wild flocks developed from a few dozen escapees in the past three decades. They favor nesting on tall electrical poles — the stadium lights of the high school and college football stadia host a lot, as do electrical transmission lines. At Verizon Wireless we had at least one occasion when one of our cell tower climbers was attacked by one of the birds, apparently a mother just after the chicks had hatched. Cell towers provide excellent habitat for the birds.
At the best sitings I’ve had, previously I lacked a camera. Today I happened to have the small Pentax Optio V20. 20 to 30 of the birds roosted along an electrical wire. They were happy to see me until I pulled out the camera. (Pure conjecture: They’re smart. They’ve seen people with cameras before — and frequently, shortly after that some crew appears with a cherry-picker to destroy their nests. Camera-shyness is a survival function for the birds.)
All I observed was social activity and some preening, except for the one bird flitting around with a stick in its bill.
And the two who were trying to pull tape off of electrical transmission wires.
Monk parakeets working to get a charge out of life, picking at insulation on an electrical wire.
Troublemakers.
Truth be told, I’ll take the monk parakeets in greater profusion, if we can reduce the populations of starlings, grackles and cowbirds.
Is there any evidence of the parakeets preying on songbirds?

[Update: Oops. Looked like a locust tree on a quick look. A longer look, I wasn't so sure. Kathryn confirmed that it's really a Chinese pistache, Pistacia chinensis.]
Cicada killer wasps appeared as early as July 7, in our yard. This year we had a cold winter, with snows that appear to have stymied even the nasty, invasive Argentine fire ant. But June was dry and hot. July came with rains, and cicada killers don’t like wet soil to dig in.
For that matter, we don’t have many cicadas, either.
Plus, we had to tear down a planter box attached to the dining room window, since it hid termites too well. No doubt that planter had young from the cicada killers in it.
This should be close to the top of “Best Places to Work.”

From my desk at the Senate Democratic Policy Committee I could look up to a crystal chandelier 10 feet across. Out the west window was a view over the National Museum of Art, down the mall to the Washington Monument and Lincoln Memorial. 25 yards away, over specially-ordered Italian tile, was the gallery to the World’s Greatest Deliberative Body. From my desk at the Senate Labor Committee I looked out on that grand Calder sculpture in the Hart Senate Office Building atrium. A couple of my memorable offices.
The work spaces I miss? That water tank in Shiprock, New Mexico, with the million-dollar view of the Shiprock; that trailer laboratory we parked in Huntington Canyon, Utah. That old dock on the Sawkill in the Hudson Valley of New York, by the old snag where the pileated woodpeckers nested and raised their brood.
Cousin-in-law Amanda Holland took this photo of her work station, above. This is a place where real science gets done. Amanda wrote:
I get to sit here for hours at a time, recording condor behavior. It does not get old. These birds are AMAZING. You can see a couple condors perched on a snag in the back of the flight pen.
Real work, for real good. That’s always the best place to work.
It became really apparent during the rains last week.
Snails crawl up the walls and plants around our patio, and appear to wait to die there. We’ve moved them back down to the soil, and they climb up again.
Kathryn remarked at the army of snails on the garage wall, beneath a bird feeder . . . that was the clue.
I don’t think ours do that eye-stalk thing. Worse for the parasites, most of the birds ignore the snails.
MacDowell’s book kept me out of church for at least a decade.
In the later pages he talks about how many copies of the Bible there are, and he says that’s an indication of how accurate it is, and that it’s the truth. That’s like saying any document I create becomes more truthful the higher the number of Xerox copies I make.
I figured that was one of the stupidest claims ever made. Maybe it was the crowd I was in with, but the more devout Christians (except for the Mormons, but that’s a different tale) swooned over the claim. I thought that any belief system that was so devoid of logic, and which required adherents to abandon all reason, was foolish.
About five years ago I picked it up again when one of our youth ministers asked me about it, and I skimmed through it again looking for any cogent, careful and compelling argument. Of course, this was long after law school and due diligence work in the law . . . I thought it more foolish than I had found it years before.
I summed it up this way for the youth minister: If there were evidence, we wouldn’t need faith. We call it a faith proudly, and we discuss the mysteries. It’s a tragedy that MacDowell has been divorced from that sweet part of Christian discovery and leap of faith. Were there evidence enough for a verdict, we’d not need faith, and it would be impossible to be anything other than an agnostic who has found the evidence.
Your mileage may differ, but if so, you need a tune-up.
