They're really clever. They have these amazing cognitive abilities.

This is Betty, she's a female raven. She's the biggest of the corvids.

And corvids in general are very, very intelligent birds.

So they can put together sequences or behaviours that they've learned

You see she'll look at things, she'll cock her head,

and you can actually see her working it out.

What is it? Can I benefit anything from that?

The hard part is trying to stay one step in front of her.

So there's a classic military line that says improvise, adapt, overcome.

And that's a really positive way of thinking about anything.

It's about trial and error and the resilience to keep going.

New Caledonian crows create multi-step tools,

which are essentially tools that are strong and thick at one end

And that means that they are able to put those tools easily into crevices

Albert Einstein described compound interest

Crows really understand compound interest.

So when they save that bit of food and bury it in the grass,

they know that over time maggots will come in

and, from the crow's perspective, they will have even more food.

It's found its food, it's saved its food,

and now it's buried it in the ground somewhere

where it gets compound interest on its investment.

She's burying food in the summer, you've got files, flies lay eggs,

maggots hatch out the eggs. So when she goes back to the food,

not only has she got the rotten bit of food she's cached anyway,

but she's doubled it in size by having all the maggots on it as well.

For a long time it was thought that delayed gratification

was something that was unique to humans and non-human great apes

but it has been found that corvids will delay gratification.

So they will deny themselves an immediate reward

in order to get a reward of a better quality in the future.

They form really long-term relationships,

Crows have absolutely nailed delayed gratification.

There's a seminal book, called The Marshmallow Test, by Walter Mischel,

which studies young children and as they've grown up

and their ability to delay gratification,

their ability to look at a marshmallow and wait,

and if they wait long enough they will get two.

What that study showed is that those children were able, later on in life,

to be better at managing money, better at managing relationships,

healthier, more likely to do exercise, more likely to eat well.

to putting off those short-term gains for long-term benefits.
