Wallace's Line: Where Two Bird Worlds Collide

Summary

This episode—which is Number 46—is about  a special place in the Malay Archipelago where two bird worlds collide. This region lies between Southeast Asia and Australia, between the Indian and Pacific oceans. And it’s crowded with about 25,000 islands, of all sizes.

Specifically, we’ll be looking at a geographic feature called Wallace’s Line. More generally, today’s episode will touch on the topic of biogeography.
