> Also I swear they have regional accents to their calls.

Its actually true they do this. Two noted ornithologist's describes it in one of their books on crows:

As ornithologist John M. Marzluff and author Tony Angell noted in their 2005 book In the Company of Crows and Ravens, the calls these birds use "vary regionally, like human dialects that can vary from valley to valley." And there's more: If a crow changes its social group, the bird will try to fit in by talking like the popular guys. "When crows join a new flock," Marzluff and Angell wrote, "they learn the flock's dialect by mimicking the calls of dominant flock members."

I live in an area that's got crows and ravens -- the ravens don't come into the city much, except for large forested parks. The crows in such parks have a few calls similar to the ravens. To me, it sounds like a rural dialect -- which is reinforced by my observations that crows don't seem to talk like that in noisier parts of the city.

I wonder if they know how to use ATMs

Here in Australia most people now buy food and drink by tapping their bank cards on a reader. Can't be long now until a particularly smart crow sees this at a beach side shop, and steals a card to copy this. Is a shopkeeper obligated to serve other species? I for one will welcome our new flying thief overlords.

Joshua Klein built a crow vending machine with some success (using coins). Tap to pay could be quite a bit more profitable, though I assume you'd have a pretty high chargeback rate.

His research claims have been disputed, and an initially favorable NYT story about him ended up being retracted. I think he probably can't be cited anymore as a credible source on the question of crow intelligence.

If this video is to be believed, they understand the concept of using a card at an ATM, but can't quite grasp exactly what to do:

To be fair, when ATMs were first introduced here, most people struggled to use them too

I think I saw a video of some bird puzzle where they have to tap the right thing with their beak to get a treat. It doesn't seem too far removed from entering a PIN code. I bet you could teach them to do that.

Also, it doesn't seem unreasonable to think they would learn to insert a credit card into the machine given that they're good at manipulating sticks and stones and putting them into places.

Tapping buttons on a vending machine and then tapping a contactless bank card seems like the most promising route for a crow to buy food.

I await a birds nest made from $20 bills.

Take a picture of that, write “capitalism” underneath then bring it to an art gallery and you’re rich.
