BBC Earth

The BBC Earth YouTube channel This is the official home for clips from David Attenborough series such as Planet Earth, Frozen Planet and Blue Planet II, so the filmmaking is as good as wildlife television gets. Most uploads are single scenes lifted from those series, which makes the channel ideal for one remarkable moment at a time rather than a structured lesson. Start with the superb lyrebird clip, in which Attenborough watches a bird reproduce the calls of other birds, a camera shutter and a chainsaw. It runs under three minutes and remains one of the strangest things ever filmed in a forest.
