David Attenborough's Natural Curiosities

Season 4 Episode 4: Curious Counters

Can animals count? This is a question that has intrigued and fooled investigators for a long time. Just over a hundred years ago, a German horse called Hans was declared a mathematical genius but all was not as it seemed. And strangely, some bamboos around the world flower exactly at the same no matter where they are – are they counting down the years?
