Readers’ wildlife photographs

March 23, 2015 • 8:40 am

Joe McClain, a reader who happens to work at my alma mater—The College of William and Mary—sent a nice sequence of photos and a story about trapping and releasing an American kestrel (Falco sparverius). I hadn’t realized how beautiful these birds are until I saw Joe’s photos (the kestrel is North America’s smallest falcon). The story:

You might be interested in the attached series of wildlife photos. They show my son, Jake, working on a kestrel project for the Center for Conservation Biology at William & Mary. Jake was an undergrad at the time and now is a grad student at U. of Arkansas, Fayetteville, working with David Krementz on a bobwhite quail project.

I went along on a kestrel hunt over on the Eastern Shore with Jake two years ago. My job was to buy lunch and take photos, but mostly buy lunch. The capture methodology is one of the coolest I’ve encountered. (Only rocket nets are cooler, in my opinion.) The device is a “bal-chatri.” It is essentially a wire mesh cage topped by a number of loops of fishing line. You capture kestrels by driving along the road, looking for Falco sparverius perched on a tree, or more often, a wire. You pull over to the side of the road, pretending to be a mailman, a toss your baited bal-chatri out onto the roadside. Then you motor down the road a ways, do a u-turn, and wait and watch.

It usually takes just a few minutes for the kestrel to fly down and get its ensnared in the bal-chatri. The idea is to be close enough to subdue and free the bird before it can injure itself. The American Kestrel is one of the smaller falcons, and Jake told me that the bal-chatris he made and used are smaller versions of  live traps that falconers have used since antiquity.

Jake looks over a male kestrel just taken from a bal-chatri:

The preferred bait is a wild-caught mouse. Lab and pet-store rodents will work, but the experience seems to traumatize domestic mice. The wild-caught mice are harder to handle, but they go through the experience with something like aplomb. I hope that if I’m ever shoved in a cage, tossed out of a car window, only to have a taloned predator hurtle down to get me, I show a fraction of the presence of mind as some of these mice. The mice are returned to the wild, usually without any visible effects from the ordeal. We were laughing about having a retirement banquet for one of the mice, complete with seed, speeches and a teeny gold watch before the retiree scampers off into the underbrush.

Kestrel and bal-chatri. Note the rebar ballast, which will ensure that the trap lands business-side up when tossed from the car window:

We ran afoul of the law while we were in the field. The Eastern Shore had been the scene of serial arsons and indeed we saw the smoke from one fire off in the distance. We followed a kestrel down a dirt road. It was indistinguishable from numerous other dirt roads we had been down already, but this was private property. A landowner called the law on us. Fortunately, the nearest lawperson was the local game warden who had been notified that researchers would be kestreling on his patch. We were admonished about the sanctity of Private Property, but gently. The warden was a good guy. He told us that our excursion had caused a bit or alarum—the postmistress had pulled her car into the end of the road until he got there.

We ended up on good terms and the warden asked if his little boy could release the kestrel. We agreed of course.

Release!:

More dosh for the book!

March 23, 2015 • 8:00 am

The latest update shows that bidding for The Fancy Book has exceeded $5,000. I can hardly believe it. Yes, perhaps (as one commenter said) the book isn’t “worth it”—but who cares? This is a lot of dough for Doctors Without Borders, and that means a lot of people helped—I hope.

Thanks again to Kelly Houle for her superb artwork that surely boosted the value. The auction still has six days to go.

Google Doodle honors mathematician Emmy Noether

March 23, 2015 • 7:40 am

Google Doodles these days to be concentrating on the contributions of women in science and technology, and today’s features Emmy Noether, a mathematician born on this day in 1882 (died 1935). If you click on the screenshot below, it will take you to the Google page, and there clicking on the picture itself takes you to a page of references about Noether.

I’m not a mathematician and hence hadn’t heard of her, but Wikipedia describes her as a big macher:

an influential German mathematician known for her groundbreaking contributions to abstract algebra and theoretical physics. Described by Pavel Alexandrov, Albert Einstein, Jean Dieudonné, Hermann Weyl, Norbert Wiener and others as the most important woman in the history of mathematics, she revolutionized the theories of rings, fields, and algebras. In physics, Noether’s theorem explains the fundamental connection between symmetry and conservation laws.

I’m sure we have some math-y readers who can explain more in the comments.  Noether was in the math department at Göttingen until 1933, when the Nazis expelled her because she was Jewish:

The following year [1933], Germany’s Nazi government dismissed Jews from university positions, and Noether moved to the United States to take up a position at Bryn Mawr College in Pennsylvania. In 1935 she underwent surgery for an ovarian cyst and, despite signs of a recovery, died four days later at the age of 53.

How many people (and how much talent) did we lose that modern medicine could have saved?

Over at Google, the artist Sophie Diao describes how she put this together:

When I first started tackling this doodle, I originally drew several concepts attempting to visualize Noether’s Theorem due to it’s [JAC: the unfortunate “artist’s apostrophe”!] revolutionary impact on the way people approach physics. But after discussing my ideas with a few professionals in the field, I decided that the doodle should include references to her mathematical work too. Noether was passionate about math, despite living in an era where women were often excluded from these subjects. While studying at the University of Erlangen as just one of two women at the school, Noether was only allowed to audit classes and needed to obtain permission from her professors in order to attend. After passing her graduation exam, she taught at the school’s Mathematical Institute for seven years without pay, frequently covering her father’s classes when he was out sick and publishing her own papers.

But there weren’t any obstacles that would stop Noether from her studies. In this doodle, each circle symbolizes a branch of math or physics that Noether devoted her illustrious career to. From left to right, you can see topology (the donut and coffee mug), ascending/descending chains, Noetherian rings (represented in the doodle by the Lasker-Noether theorem), time, group theory, conservation of angular momentum, and continuous symmetries–and the list keeps going on and on from there! Noether’s advancements not only reflect her brilliance but also her determination in the face of adversity.

 

Monday: Hili dialogue

March 23, 2015 • 6:58 am

Oy, I had little sleep last night, and it was freezing to boot. And another long week begins. Will something good happen?  Meanwhile in Dobrzyn, Hili shows her Semitic temperament: the feeling that something is wrong, no matter what the data:

A: What are you looking at? Did something frighten you?
Hili: Not yet. I’m just checking whether everything is in order.

P1020421

In Polish:
Ja: Czemu się tak przyglądasz? Wystraszyłaś się czegoś?
Hili: Jeszcze nie. Sprawdzam czy wszystko w porządku.

 

Damn, more snow here!

March 23, 2015 • 6:40 am

Imagine my surprise when, not having looked out the window, I checked the weather report on my laptop to find this:

Screen Shot 2015-03-23 at 6.09.48 AM

HEAVY snow!

And indeed, it’s snowing—and heavily indeed. It’s predicted to taper off this afternoon, but there’s already an accumulation, and I was frosted like a cake when I arrived at work. This is a surprise: we were supposed to have no snow today, and only a light dusting yesterday, which never materialized.

Here’s the view on my walk to work; you can see Frank Lloyd Wright’s famous Robie House to the right, one of the highlights of my twice-daily perambulation:

But geez, when will the winter ever end?? And does it mean that I’m old when I talk about the weather?

A hilarious mimetic parrot (and lagniappe)

March 22, 2015 • 3:45 pm

Reader Ursula sent in an amazing video of a parrot imitating her friend. Now this is awesome (video quality isn’t optimal, but the sound is what counts). The backstory:

My friend Ken acquired a yellow-naped Amazon parrot, named José, from a woman who apparently spent a lot of time on the telephone. Ken discovered that when Jose is alone (he doesn’t do it when people are around), he’ll occasionally give a slam-dunk rendition of her phone persona. Ken snuck up on him to record this one-minute video:
It’s even more amazing when you realize that for some of this the bird must have had only one take before he imitated it.
And here’s lagniappe, though I have a feeling I’ve posted this before:

 

Mississippi passes “Jesus take the wheel” bill, exempting church drivers from commercial licensing statutes

March 22, 2015 • 2:45 pm

Of all the exemption laws for stuff like medical care, vaccinations, and blood transfusions, this one makes the least sense. Last month, the Mississippi House of Representatives passed a bill exempting drivers of church buses (but not other buses of similar size) from having to pass the state’s commercial driver’s license test. The Clarion-Ledger of Jackson, Mississippi tells the story:

House members on Thursday [Feb. 5] passed a bill exempting mid-sized church buses from the state’s commercial driver’s license requirements, prompting one lawmaker to call it the “Jesus Take the Wheel Act.”

Current law requires CDL-certified drivers for any vehicle transporting more than 16 passengers, including the driver. The bill would amend that law to exempt church buses designed to carry 30 passengers or less.

[JAC: “Jesus Take the Wheel” is the title of a Carrie Underwood song about a mother who, driving with her baby in the car, hits a patch of black ice, skids, and then takes her hands off the wheel, asking Jesus to steer. Of course Jesus did, everyone was saved, and the mother accepted Jesus as her savior. You can hear that execrable ditty here.]

The bill, HB 132, would help congregations lacking a CDL-certified driver transport up to 30 passengers in a church-owned vehicle. Although applying equally to all churches, it’s primarily aimed at smaller congregations with fewer members and financial resources.

It now heads to the Senate for consideration. [JAC: I don’t think the Senate’s voted on it yet.]

“This just allows small churches, some don’t have people with commercial licenses at all, and they can pick a person to drive the bus,” said state Rep. Robert Johnson III, D-Natchez, who chairs the Transportation Committee which had passed the bill earlier in the session.

Here’s a thirty-passenger van pictured by The Daily Kos. It ain’t small! I’d think one would have to take a test to be qualified to drive people around in that.

 The Clarion-Ledger continues:

When contacted by The Clarion-Ledger, longtime CDL-certified driver Troy Coll of Hattiesburg called the measure potentially dangerous.

“I think this bill is trading the safety of everyone on the road for the convenience of those operating church vehicles,” Coll said. “Since the bill covers vehicles up to 30 passengers, we’re not just talking vans with extra rows of seats – these are buses, with long frames and much larger blind spots than passenger vehicles.”

Commercial certified bus drivers must pass a written test and a driving test and also must get a CDL Medical Card, which requires the driver pass a physical.

“Obtaining a CDL is not especially difficult,” Coll said, “but the testing does increase the level of scrutiny on drivers, and the medical requirements prevent individuals with poor vision/hearing/motor control or untreated diabetes from driving large vehicles full of vulnerable passengers.”

I’m not sure what the rationale for this law is, unless it’s somehow to relieve churches of the onerous burden of having their drivers get qualified, and of course endangering passengers’ safety at the same time. Or perhaps churches aren’t considered “commercial” operations. But I bet other noncommercial ventures that have such buses must get their drivers qualified. Pity Jesus can’t really take the wheel!

Judith Shulevitz on the breathtaking inanity of college “safe spaces”

March 22, 2015 • 1:00 pm

I could be accused of being a curmudgeon when I decry the proliferation of “safe spaces” on college campuses (including mine)—spaces designed to protect people from “hate speech” that, broadly construed, means “speech that I don’t like.” When I posted about the Columbia University flyers proclaiming student dorm rooms to be “safer spaces” because they weren’t “oppressive,” I took some flak from those who thought that such spaces were useful.  And, indeed, they could be, but my point was that this kind of thing is growing rapidly on American campuses, and they’re inimical to the idea of college as a place where one learns how to deal with and counter  (or even learn from) speech that seems challenging or repugnant.

So I was pleased to see a younger person—the New Republic editor and writer Judith Shulevitz—echo my sentiments (in a much better and more extended piece) in today’s New York Times: “In college and hiding from scary ideas.” The piece is Recommended Reading from Professor Ceiling Cat™.

Shulevitz starts her piece by describing a “safe space” that puts my teeth on edge: something that Brown University, a hotbed of political correctness, did when students sponsored a debate between two women on the topic of campus sexual assault. One of the debaters, Wendy McElroy, was thought likely to criticize the phrase and idea of “rape culture.” Just that possibility threw the students and administration into a tizzy, for such criticism could be seen as “invalidating people’s experiences” and “damaging.” And so Brown set up a competing talk to confirm that we do indeed live in a rape culture. They also set up a safe space:

The safe space, Ms. Byron [a senior student at Brown] explained, was intended to give people who might find comments “troubling” or “triggering,” a place to recuperate. The room was equipped with cookies, coloring books, bubbles, Play-Doh, calming music, pillows, blankets and a video of frolicking puppies, as well as students and staff members trained to deal with trauma. Emma Hall, a junior, rape survivor and “sexual assault peer educator” who helped set up the room and worked in it during the debate, estimates that a couple of dozen people used it. At one point she went to the lecture hall — it was packed — but after a while, she had to return to the safe space. “I was feeling bombarded by a lot of viewpoints that really go against my dearly and closely held beliefs,” Ms. Hall said.

Well, that sounds like an infantilizing gesture to me: really, cookies, bubbles, coloring books, and Play-Doh—the accoutrements of children? But so be it. And, indeed, Shulevitz says that such spaces could be useful, but then goes on to argue, as I do, that the notion has an insidious way of spreading like The Blob, killing off free speech as it goes along:

But the notion that ticklish conversations must be scrubbed clean of controversy has a way of leaking out and spreading. Once you designate some spaces as safe, you imply that the rest are unsafe. It follows that they should be made safer.

Yes, and that’s what’s happening all over America, including at my own university. Shulevitz then recounts a bunch of alarming episodes on campuses that show the extremes of the “safe space” movement. Here are just a few (her words):

  • A year and a half ago, a Hampshire College student group disinvited an Afrofunk band that had been attacked on social media for having too many white musicians; the vitriolic discussion had made students feel “unsafe.”
  • Last fall, the president of Smith College, Kathleen McCartney, apologized for causing students and faculty to be “hurt” when she failed to object to a racial epithet uttered by a fellow panel member at an alumnae event in New York. The offender was the free-speech advocate Wendy Kaminer, who had been arguing against the use of the euphemism “the n-word” when teaching American history or “The Adventures of Huckleberry Finn.” In the uproar that followed, the Student Government Association wrote a letter declaring that “if Smith is unsafe for one student, it is unsafe for all students.”

    “It’s amazing to me that they can’t distinguish between racist speech and speech about racist speech, between racism and discussions of racism,” Ms. Kaminer said in an email.

Shulevitz also criticizes the Columbia University “safer space” initiative. There’s one more episode she recounts in detail, but I’ll save it for last because it’s close to home.

Why is this happening now? Shulevitz floats several theories: students are more cosseted now because college admissions selects for students who avoid risks and challenges (I’m not sure about that idea); that students have “medicalized” their discomfort (citing trauma, triggering, mental illness, and so on) because administrators must respond to such complaints, which cite a “hostile environment”, something the U.S. government explicitly decries; and, finally, the writings of some feminist and anti-racist legal scholars in the 1980s and 1990s which equated uncomfortable speech with psychological injury.  I’d add that there may be a new element of narcissism in there, too, as students increasingly look at college education as a way to get a job rather than make their minds more inquisitive and supple. The growth of “me-ness” may breed students who are solipsistic, resenting assaults on the walls of their egos.

Regardless, the issue is a problem, and one we should guard against. One person’s hate speech is another’s free speech, and colleges, above all, are places to challenge your ideas, not reinforce what you already believe. (That’s what religion is for.)

At the end, Shulevitz gives an anecdote from the University of Chicago, one that caused a big kerfuffle here just a few weeks ago. Here’s her description, and it’s absolutely accurate:

A few weeks ago, Zineb El Rhazoui, a journalist at Charlie Hebdo, spoke at the University of Chicago, protected by the security guards she has traveled with since supporters of the Islamic State issued death threats against her. During the question-and-answer period, a Muslim student stood up to object to the newspaper’s apparent disrespect for Muslims and to express her dislike of the phrase “I am Charlie.”

Ms. El Rhazoui replied, somewhat irritably, “Being Charlie Hebdo means to die because of a drawing,” and not everyone has the guts to do that (although she didn’t use the word guts). She lives under constant threat, Ms. El Rhazoui said. The student answered that she felt threatened, too.

A few days later, a guest editorialist in the student newspaper [JAC: you can see that editorial here] took Ms. El Rhazoui to task. She had failed to ensure “that others felt safe enough to express dissenting opinions.” Ms. El Rhazoui’s “relative position of power,” the writer continued, had granted her a “free pass to make condescending attacks on a member of the university.” In a letter to the editor, the president and the vice president of the University of Chicago French Club, which had sponsored the talk, shot back, saying, “El Rhazoui is an immigrant, a woman, Arab, a human-rights activist who has known exile, and a journalist living in very real fear of death. She was invited to speak precisely because her right to do so is, quite literally, under threat.”

You’d be hard-pressed to avoid the conclusion that the student and her defender had burrowed so deep inside their cocoons, were so overcome by their own fragility, that they couldn’t see that it was Ms. El Rhazoui who was in need of a safer space.

That last sentence is a zinger, and right on the mark. It’s time to stop infantilizing college students. No more Play-Doh, no more cookies—it’s time to put away those childish things. College students are adults; they’ll soon enter a rough-and-tumble world. What better way to prepare for that world than learning to deal with those whose ideas discomfit you?
