Now biologists have revealed why New Caledonian crows go to such an extent to craft the bespoke hooks: for their love of “fast food”.

In this video filmed by John Downer Productions, a crow realizes it can’t reach the bugs inside a narrow hole, so it finds a small stick and proceeds to go fishing.

And biologists from St Andrews and Edinburgh Universities have discovered that using a hooked stick lets the crows wine out bugs and seeds up to 10 times more quickly than a straight stick.Their study in Nature Ecology & Evolution found that the birds go to enormous lengths to make the hooks – but that it pays off.
