Nature - Season 34 Episode 8 Natural Born Hustlers: The Hunger Hustle

Exploring the duplicitous ways in which animals try to secure their next meal. Singled out is the devious drongo, a South African bird. In winter, he has to rely on grubs and insects that live underground, but other animals are far better equipped to dig them up, so the drongo devises a con. He serves as lookout while vulnerable social weaver birds are on the ground digging up food. Among other segments: the orchid mantis, which attracts insects by mimicking a flower and why it is even more successful than the real thing; how killer whales use sound to manipulate the behavior of herring to their advantage; and how and why gray squirrels practice sleight of hand to protect the nuts they’ve gathered to get them through the winter.
