Earlier this year, Jonathan talked about the amazing Monarch Butterfly with Jaap de Roode. One thing that was mind blowing in that interview was the story of the butterfly’s migratory journey which saw them travel up to 4,500 Km in about 6 weeks from Southern Canada to Mexico.

This got us thinking about the many amazing journeys animals partake in and more to the point how they achieved such amazing feats of navigation.

So, this time Jonathan was joined by David Barrie is the author of Incredible Journeys: Exploring The Wonders of Animal Navigation (also published as Supernavigators in North America) to talk about animals' fascinating journeys and abilities to navigate across the globe.
