A Hungry Snake Finds a Whole Colony of Sociable Weavers

Short | 01:48

Nesting in close proximity to each other has a lot of advantages for sociable weavers. But if a predator like this venomous boomslang discovers the nests, he can wipe out the entire colony's brood in hours.

More About This episode

It stands tall in the semi-arid desert of the Kalahari, giving its inhabitants much-needed shade during summer days, large pods when food is scarce, and a foundation for one of the most remarkable constructions built by a colony of birds. It's the camelthorn, one of only a handful of large trees that can take root in the Kalahari's deficient soil. Discover the evolutionary secrets that allow it to tower as a master of survival in the vast expanses of these African plains, where living is an often unthinkable challenge.
