Hummingbirds: Up close and personal

It takes a filming speed of 200-to-500 frames per second to capture the fast-moving world of the hummingbird at a level where we can really see what's going on. So what are hummingbirds up to? Videographers for a Nature documentary caught hummingbirds foraging for insects, bonking each other on the head in order to get access to a tasty flower, and living happily in high mountains where they hop along the ground to feed off plants growing close to the soil.

Filmmaker Ann Prum explains the nifty technical nitty gritty behind making a movie about hummingbirds and how new ways of observing the birds are teaching us new things about their lives.
