And for great grey owls, it is the iciness of the snow that is hampering their hunts. Yellowstone's winter is always one of the most brutal on the planet. But 2016 saw weather records broken, and the wildlife was forced to adapt to survive. Kate Humble gets to grips with the science behind this remarkable season, from understanding the importance of the snowpack's structure as the melt begins to uncovering why Yellowstone's unique geology poses problems for some grazer's teeth.

The members of the Nsefu pride take a huge risk: they're leaving their home turf, and crossing the Luangwa River in search of prey. Navigating croc-infested waters is a challenge, especially for the pride's yearling, dubbed the Misfit. It's a foolhardy gamble, but hunger has forced their hand. If they're to succeed, they'll need the Misfit to come of age-their very survival depends on it.
