Built for the Kill
Saturday, 7.30pm, Nat Geo Wild This series about natural predators continues with a fascinating investigation into North America’s most fearsome predator, the grizzly bear. While there is a fair amount of David Attenborough-style vision of baby bears (born blind at a birth weight of 1kg) and mothers venturing out with cute cubs in the snow, the emphasis is on the capacity for hostility of these powerful creatures. Some terrific animated info-graphics clearly explain how the bodies of bears are built for the kill. The greatest danger to a mother bear with cubs is other bears. Vicious bouts also occur between rival males. But the headline stoush is between the grizzly and the wolf. Actually, the wolf pack. Working together, the much smaller creatures often have the advantage.
