The world famous Little Penguins of Australia's Phillip Island entertain half a million tourists a year with a sunset parade from the surf to their burrows. But behind the scenes, the penguins lives are even more interesting. Penguin Island uses the latest underwater satellite tracking and Big Brother-style video surveillance to follow the lives of several penguin families who live in a colony where relationships are fraught and survival is tenuous. Over six half-hour episodes, Penguin Island follows the penguins as a dedicated team of rangers and scientists monitor and protect them through the hottest summer on record.
