Which animals and Spy Creatures are in this episode?
1
Kea
The world's cleverest bird, and the only alpine parrot, the kea lives in the southern Alps of New Zealand. These remarkable birds are very cautious about Spy Kea, who is there to film their social gatherings, and are intrigued by SnowballCam.
2
Wallaby (and wombat)
In the mountains of Tasmania, Bennett's wallabies are joined by Spy Wallaby. Like all the Spies, Spy Wallaby needs to be accepted by the creatures it is watching - which turns out to include bare-nosed wombats as well, whose strong claws allow it to unearth hidden roots.
3
Sea Otter
We meet sea otters in Alaska, and Spy Otter. Overcoming their shyness, the real otters are intrigued by the Spy and we get an insight into their world.
Using the latest drone technology, Spy Eagle provides aerial coverage of the sea otters and their courtship behaviours, including some alarming behaviour by a dominant male towards a female and her young pup.
4
Emperor penguin
In the Antarctic, emperor penguins are spied upon by a variety of cameras including one that toboggans! The Spy Creatures capture a range of fascinating penguin behaviours, including what the adult penguins without chicks get up to. Watch a clip of penguin chicks facing a giant petrel.
5
Polar bear
In the Arctic, the cameras wait patiently for a mother polar bear and her cub to emerge from their den. Snowball Cam proves to be of interest to the polar bears, and the resulting clips are wonderful to watch. Watch a clip on the Spy in the Snow website.
