Episode 3 Preview | Crowded Skies

30s

The sky is a crowded world where mammals, birds and insects hunt, escape, mate, defend territory, sleep, and even die on the wing. Survival up here depends not just on beating gravity or mastering flight, but also out-flying the competition.

Extras + Features

A Flying Squirrel’s Greatest Threat is the Great Horned Owl

S1 - 2m 47s

Gliding allows flying squirrels to find scarce food fast, even in the depths of a North American winter. The longest limbs in the squirrel world make their wings as large as possible. But flights are kept short and fast to help the squirrel avoid a major predator - the Great Horned Owl.
Wood Ducklings Take a Leap of Faith on the Day They Hatch

S1 - 2m 50s

Wood ducks make a nest high in the trees to protect their eggs from predatory woodpeckers, raccoons, snakes and alligators. Although the eggs are laid over a two-week period they all hatch on the same day and the mother has just minutes to get the twelve noisy chicks to safety.
