> Each volunteer was either holding a dead crow, standing near a dead red-tailed hawk—a crow predator—or standing near a dead red-tailed hawk holding the dead crow. I had to reread this about 5 times to make sense of it. Am I just tired from a long work day or is that a poorly phrase sentence?

holding a dead crow, standing near a dead hawk, or doing both at once.

It's not clear whether the volunteer or the hawk is holding the dead crow in the last case.

If you find this interesting, you should really look into the intelligence of crows. They've been observed to remember human faces, wait on traffic lights, plan, and a whole bunch of things that are very impressive. And don't even get me started on _jackdaws_.

Corvids (crows, ravens, magpies, jackdaws) are pretty bright. Some of them also have quite a bit of voice control. Like parrots, they can speak human words if trained. https://youtu.be/rIX_6TBeph0

This Raven speaking Finnish is pretty cool: https://www.youtube.com/watch?v=yOVYMQP7gMM

You realize you're not supposed to toss around garbage in the national park?

Biodegradable apple cores that he was feeding to birds? I think that hardly qualifies.

Well, ideally "leave no trace" and "don't mess with wildlife" are adhered to when in nature

edit: it's also illegal in national parks, carrying up to a $5000 fine and six months in jail

Is there any evidence this isn't fake?

He does sound a little like a voice synthesiser, but I think that's mostly because both birds and computers speak English poorly. Here's another example: https://youtu.be/AfsnHVaScjg

Re: voice synth, I think that's just an artifact of how birds vocal chords (or whatever gizmo they've got in there) work. The timbre of the voice is going to be different than that of a primate.

EDIT: you can even hear it in their natural calls, they have a buzzing, saw-like texture in the upper-mid and high range.

Probably a ridiculous claim, but I think ants have a ant death detection system too. After being invaded, putting dead ants on the path they used to reach the food drawers made them backtrack immediately and stop using that trail altogether.

I believe ravens and crows are very similar, this is a personal (long, and not the great) story about a raven I messed around with in Yosemite National Park: When I was up on north dome (not to be confused with half dome) there was a group of raven's hanging out on the rocks watching us eat our late lunch. I had an apple core that I tossed to the side and watched as a raven warily tried to approach it. I walked over…

Boy, there's one in every thread, huh?

Okay, so these are the kinds of things that definitely need a citation ;) In what sense do you mean reading minds? Genuine mind reading, or basically a kind of intuiting about human intention based on say, body language?

Sorry, no citation. Just my personal knowledge and experience. And it's not just reading body language, but actual reading your thoughts. In the case of the crow, what body language tells it that the guy is about to throw a piece of rock or a bone when it can't SEE the object? I know it's not something I can prove to you, but that doesn't mean it's not happening.

No, that is pretty much the definition of "not happening".

For last 2 years, I am suffering from depression. I decided to isolate myself, which I knew was wrong. My parents were worried about my situation since I am living with them. I live in a village where this sort of behavior is condemned, and people are very hardworking(they are either farmers, fishermen, construction workers/helpers). What I noticed was, whenever I go outside of my house a bunch of crows will gather around and caw at me, until I disappear from their site. But they wont follow me in the streets. Some times more than 30 crows will gather near the trees, and kinda shout at me. (I always felt like they were yelling at me, to get a life :) )

So I decided to give a try to get more disciplined. From past to months I wake up at 5 am for gym, and have a routine life. Now none of the crows notice me :).

My explanation: These crows can sense how people live and behave. And they found out I was very odd in the community. :) :)

So here's a story for the books. I live in Sri Lanka and we have massive numbers of crows always flying around in the urban areas causing quite the racket too. They are exceptionally intelligent and have been witnessed hitching bus rides regularly from one town to another. But the story I have happened at a school water polo match.

The location the match was being played at had a standard pool and a shallow junior pool right next to each other. During the match a wild attempt to score a goal missed the side and the ball smashed full force into a crow who was drinking water from the junior pool. This of course resulted in the poor crow's death. But what was amazing was that within a few minutes, every other crow in the vicinity had surrounded the dying crow and then decided that they would attack the spectators and the players. We had to clear the entire stadium and pool for a good half an hour till they allowed us to return (although they left their dead comrade behind who had to be cleared away by a hapless cleaning staff member).

One less impressive story but still relevant to the article. We had an antique air rifle at home that needed repairs. My uncle who did such repairs said he'd come along and look into it. That evening there were plenty of crows around as usual. Most of them were in the trees two houses away. I assume these were crows who had forever lived in urban areas and probably never been shot at let alone seen a gun. They've lived through plenty of fireworks and don't seem all that bothered by them whenever they do go off. But when I brought the gun out to show to my uncle, the ruckus caused was utterly deafening. And just like that, silence. Every single crow had scattered from the area. How they recognised an object like that and so instantly is a question and memory that has stuck around with me forever.

Amazing creatures who annoy me with their never ending din and tendencies to somehow make a mess of any garbage bag left out in the open, but they'll always have my absolute respect for their intelligence.
