A new film series about animal behaviour and survival.

Hugh Falkus and Niko Tinbergen, who made the award-winning film Signals for Survival about the language of herring gulls, have now turned their attention to the Oystercatcher.
It is a common bird, yet has an amazing skill unique among birds. It is able to use its bill to open a mussel and extract the flesh. But how does it acquire this extraordinary skill?
