Marty Stouffer's Wild America
Season 5 Episode 8 - The Grouse and the Goshawk
1982
Documentary
Most predators and prey have evolved in unison. They are so closely matched that every day is an "Animal Olympics." Intimately linked together are two birds -- the speedy Goshawk and the alert Ruffed Grouse. Many predators pursue the Grouse, but none is so well-adapted to catch it as the Goshawk. This is the story of an unerringly precise natural balance.
