I once wrote a personal’s ad in SQL on Craigslist, back when they had that section. A DBA replied and asked if I wanted hawking. She had a Cooper’s hawk. I met her at a commercial park in a Saturday morning. She was driving a Honda CRV, the hawk was in the front passenger seat, and I hopped into the back seat. She started driving and spotted some crows. The hawk saw them as well. Wearing a “don’t kill me either your…

I once threw a tennis ball straight up, just as a bird happened to be flying past, it rolled right and dodged it by a cm.

I don't really know what it's like to be a bird, of course, but I have to imagine their subjective experience of duration differs greatly from ours.

Search for "flicker fusion rate" to learn a lot more about this.

> Cooper’s hawk is on a rather short list of bird of prey species that have successfully adapted to life in cities. A city is a difficult and very dangerous habitat for any bird, but particularly for a large raptor specializing in live prey: you have to avoid windows, cars, utility wires, and countless other dangers while catching something to eat every day. Peregrine falcons adapted quite well, and they're much more…

There's a couple of peregrine falcons with a live streaming webcam on top of Cathédrale Sainte-Cécile in Albi, south of France

Not OP, but I'm friends with crows. Imagine having to try to explain that...

The other day when visited local city park (in South London) I spotted a Buzzard just chilling on the tree among pigeons. Small, but majestic nonetheless.

Obligatory note that if you're from the US you are probably picturing a different bird than parent saw.

The point the story tries to make is that the Hawk learned traffic signals. That is not necessarily the case. It could be that the hawk just sees that the cars are blocking the sight of the prey.

Still an intelligent action, only does not mean the hawk understands the signal itself.

Well, there is survivor bias there, of course; you don't see the ones that didn't learn to dodge...

We call that evolution

Nit pick, but it’s natural selection

The cars aren’t evolving the birds, but they are selecting the fittest.

the story as told outlines that the hawk will stage itself when it hears the sound of the crosswalk, in anticipation of the line of traffic getting long enough for it to use as concealment.
