PBS Nature - Natural Born Hustlers 2of3 The Hunger Hustle 720p x264 HEVCguy

The duplicitous ways in which animals try to secure their next meal is the subject of the second episode, The Hunger Hustle. 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. If a predator is spotted, he sends out an alarm call and the weavers head for safety until they get an all clear call from him. But the drongo also issues fake alarm calls, allowing him to eat food the weavers have dug up before issuing an all clear to return. 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.
