#92Crazy to see this posted today. Last night my wife and I were on a reservation in Arizona and watching the birds. She googled this very topic. Then when I looked at HN today, here it is! I showed it to her and the first thing out of her mouth was, “Is Facebook listening to me?” Then I had to explain that HN is human-powered and the chances of Big G and Facebook and HN sharing data is pretty close to zero.

#93Have you ever exchanged a look with a stranger and their expression was such that you immediately got a deep impression of their inner life, of their humanity, and felt a connection? That happened to me with a raven, while we were both enjoying a stunning view of a sunset at Petrified Forest National Park. It was a large, old, rumpled, wise seeming creature. Surely that environment primed me for the experience. The m…
Scott Alexander has a good post on bird intelligence here: https://slatestarcodex.com/2019/03/25/neurons-and-intelligen... Though they have much smaller brains, there is evidence to suggest that their brains are 10x more computationally dense.

This is a hooded crow hammering / trying to kill what probably thinks is a prey. Seems more frustrated than happy. The easiest crow to identify in Europe, being gray and black.
How about these? When they roll on their backs down a snowy slope, are they playing? https://www.youtube.com/watch?v=h7GmYJnUtsY
How about this video, are they playing? https://m.youtube.com/watch?v=C59YIwMcg3Y

So you adopted a dog. How did you go about buying all the things you need when you suddenly have a dog? Stores? Online? Amazon? Did you use a credit card? Did you research dog food? Post on Facebook or Twitter about how you were getting a dog?
I didn't actually adopt a dog. I merely spoke about the idea of doing so to a friend.

#97However, during the detailed analysis it was noted that varying colors of paints appeared on the bird's beaks and claws. By analyzing these paint residues it was determined that 98% of the crows had been killed by impact with trucks, while only 2% were killed by an impact with a car.
MTA then hired an Ornithological Behaviorist to determine if there was a cause for the disproportionate percentages of truck kills versus car kills.
The Ornithological Behaviorist very quickly concluded the cause: when crows eat road kill, they always have a look-out crow in a nearby tree to warn of impending danger.
The scientific conclusion was that while all the lookout crows could say "Cah", none could say "Truck."

#98Here's a very cool Google Creative Labs experiment that used tSNE to organize thousands of bird chirps/songs/calls. The result is an interactive map that groups similar bird sounds (click/tap to play any of the sounds): https://experiments.withgoogle.com/ai/bird-sounds/view/ source code: https://github.com/googlecreativelab/aiexperiments-bird-soun...

That's a sure sign you are watching ravens, not crows. Ravens can play together in the air in ways crows never do.

The New Caledonia Crow is getting a lot of study for its puzzle-solving abilities.
