Convention Countdown

The Republican National Convention is in 4 days in Cleveland.

The Democratic National Convention is in 11 days in Philadelphia.

NASA has released the first picture of Jupiter taken since the Juno spacecraft went into orbit around the planet on July 4.

The picture was taken on July 10. Juno was 2.7 million miles from Jupiter at the time. The color image shows some of the atmospheric features of the planet, including the giant red spot. You can also see three of Jupiter's moons in the picture: Io, Europa and Ganymede.

The Senate is set to approve a bill intended to change the way police and health care workers treat people struggling with opioid addictions.

My husband and I once took great pleasure in preparing meals from scratch. We made pizza dough and sauce. We baked bread. We churned ice cream.

Then we became parents.

Now there are some weeks when pre-chopped veggies and a rotisserie chicken are the only things between us and five nights of Chipotle.

Parents are busy. For some of us, figuring out how to get dinner on the table is a daily struggle. So I reached out to food experts, parents and nutritionists for help. Here is some of their (and my) best advice for making weeknight meals happen.

"O Canada," the national anthem of our neighbors up north, comes in two official versions — English and French. They share a melody, but differ in meaning.

Let the record show: neither version of those lyrics contains the phrase "all lives matter."

But at the 2016 All-Star Game, the song got an unexpected edit.

At Petco Park in San Diego, one member of the Canadian singing group The Tenors — by himself, according to the other members of the group — revised the anthem.

School's out, and a lot of parents are getting through the long summer days with extra helpings of digital devices.

How should we feel about that?

Police in Baton Rouge say they have arrested three people who stole guns with the goal of killing police officers. They are still looking for a fourth suspect in the alleged plot, NPR's Greg Allen reports.

"Police say the thefts were at a Baton Rouge pawn shop early Saturday morning," Greg says. "One person was arrested at the scene. Since then, two others have been arrested and six of the eight stolen handguns have been recovered. Police are still looking for one other man."

A 13-year-old boy is among those arrested, Greg says.

After an international tribunal invalidated Beijing's claims to the South China Sea, Chinese authorities have declared in no uncertain terms that they will be ignoring the ruling.

The Philippines brought the case to the Permanent Court of Arbitration in The Hague, objecting to China's claims to maritime rights in the disputed waters. The tribunal agreed that China had no legal authority to claim the waters and was infringing on the sovereign rights of the Philippines.

Donald Trump is firing back at Supreme Court Justice Ruth Bader Ginsburg after she disparaged him in several media interviews. He tweeted late Tuesday that she "has embarrassed all" with her "very dumb political statements" about the candidate. Trump ended his tweet with "Her mind is shot - resign!":

Do Birds Hold Funerals?

Sep 6, 2012
Originally published on June 20, 2014 6:17 pm

Here's a journal-paper title that grabbed my eye: Western scrub-jay funerals: cacophonous aggregations in response to dead conspecifics.

OK, there's some jargon included — "cacophonous aggregations" refers to birds called in by other birds' vocalizations, and "conspecifics" just means other individuals of the same species. But it's the "f" word — funeral — that caught my attention.

The paper, published online last week by the journal Animal Behaviour and written by T.L. Iglesias, R. McElreath, and G.L. Patricelli at the University of California-Davis, describes a series of fascinating experiments set up to gauge scrub-jays' responses to dead companions.

But here's the thing: nowhere in the text does the word "funeral" appear. That term is reserved for the title. So why use the term at all, and do birds really hold funerals?

Scientists already knew that some corvids — crows and ravens — make alarm-call vocalizations when they discover the body of another bird. Iglesias et al. wanted to carry out an experimental (rather than only observational) study using a corvid species. So they trained scrub-jays to show up at a feeder at certain times, and then tested the birds' responses to certain situations.

For instance, they presented the birds with a novel object made of wood, approximating the form of a dead scrub-jay, and some days later presented them instead with the actual skins (plus feathers) of dead jays. The birds never called or formed cacophonous aggregations in response to the wood object, but they always called at the skins, and almost always these callings escalated into noisy gatherings.

In another test, the birds were shown the jay skins and (at different times) mounts of dead great horned owls in a perched position. To both stimuli, jays responded with calls and noisy gatherings at about the same, high rate. Only with the fake owls, though, did the birds carry out mobbing behaviors.

From the sum total of their experiments (not all of which I've described here), Iglesias et al. conclude something interesting:

"Our results show that, without witnessing the struggle and manner of death, a dead conspecific was used as public information about risk, and that this information was actively shared with conspecifics and used to reduce [by temporarily decreasing foraging in the area] exposure to risk."

In other words, the birds tell each other about a dead companion, and so individually and collectively the scrub-jays may learn something about predation risks. By calling in others (the cacophonous aggregations), they may be more likely to drive a predator away or to warn relatives and mates of danger.

Where is the funeral promised in the title? Via email, I asked lead author Teresa Iglesias about this, and she replied:

"I do not wish to imply anything about the occurrence (or absence) of an emotional or cognitive response by using the word 'funeral.' The use of the term in the title is due to the fact that it has been used to describe animal responses to their dead in many other species (crows, magpies, ravens, elephants, chimps ... ) and I wanted to make sure this work could be linked to those anecdotal observations."

It's correct to note that "funeral" has been used in nonhuman-animal contexts before. Take a look at this article in Yes! Magazine by animal-behavior expert Marc Bekoff. Bekoff writes:

"I once happened upon what seemed to be a magpie funeral service. A magpie had been hit by a car. Four of his flock mates stood around him silently and pecked gently at his body. One, then another, flew off and brought back pine needles and twigs and laid them by his body. They all stood vigil for a time, nodded their heads, and flew off."

And it's not only birds. Bekoff continues:

"I also watched a red fox bury her mate after a cougar had killed him. She gently laid dirt and twigs over his body, stopped, looked to make sure he was all covered, patted down the dirt and twigs with her forepaws, stood silently for a moment, then trotted off, tail down and ears laid back against her head."

In my book How Animals Grieve, coming out in April, I detail a host of examples of animal grief and mourning, a few of which relate to this sort of apparently ceremonial context.

Iglesias, however, means to use the word "funeral", as she put it to me, "only to the extent that it is an animal paying attention to another dead animal" (though excluding behaviors such as scavenging).

Here's the bottom-line question, then: When is the term "funeral" inappropriately anthropomorphic?

Iglesias asks, reasonably, that the scientific merit of the paper not be lost in a dust-up around this question. I agree, because her team has told us something really valuable about corvid intelligence and communication.

On the other hand, if you put the f-word into an article title, but divorce its meaning from any evidence of care for the body and/or expressed emotion, you'd better be prepared for skepticism.
