Storm is an extraordinary wolf - the head of a pack in Canada's frozen north that hunts the giant buffalo herds............ This pack came to fame in the BBC tv special FROZEN PLANET where cameraman Jeff Turner spends a year with Storm and his wolf family, learning how they survive in this harsh wilderness and whether Storm can pass his hunting skills on to the new generation of wolf cubs............ If you remember the wolves hunting buffalo in Frozen Planet, you'll enjoy this: a whole film devoted to those chases, where the pack harries a herd of buffalo until one gets unlucky............... The buffalo are enormous — up to a ton in weight — and if they stand their ground, the wolves don't have a hope............. Standoffs can last for days, until the wolves find a way to get the buffalo moving............. Then they chase the herd for up to 20 miles until an adult stumbles or a calf gets separated, and they're in........ The film-makers are squeamish about showing the actual kill ("It's hard to watch these predations, but death is a crucial part of the natural cycle," they tell us apologetically)............ But it's still powerful stuff, and the pack leader — nicknamed Storm — is a powerhouse of an Alpha wolf............ Jeff Turner spends a year in northern Canada filming the life of a wolf pack that featured in the David Attenborough series Frozen Planet............ The cameraman learns how the animals survive in the harsh wilderness and discovering whether the pack leader can pass its hunting skills on to a new generation of cubs........... The gray wolf is the largest member of the wolf genus, with males averaging 43--45 kg (95--99 lb), and females 36--38.5 kg (79--85 lb)...................click on the link below to watch the full film, about an hour in length
