Can animals count?

BBC World Service - CrowdScience, Can animals count?

CrowdScience finds out whether there are some creatures that have a way with numbers.

Mathematics and our ability to describe the world in terms of number, shape and measurement may feel like a uniquely human ability. But is it really? Listener Mamadu from Sierra Leone wants to know: can animals count too? 
CrowdScience presenter Marnie Chesterton goes on a hunt to uncover the numerical abilities of the animal kingdom. Can wild lions compare different numbers?  Can you teach bees to recognise and choose specific amounts? And if the answer is yes, how do they do it? Marnie tries to find out just how deep the numerical rabbit hole goes… and comes across a parrot named Alex who is perhaps the most impressive example of animal counting of them all.
