It's March and light returns to the high
0:07
Arctic, sweeping away four months of
0:10
darkness.
0:24
A polar bear stirs.
0:26
She has been in her den the whole
0:28
winter. Her emergence marks the
0:32
beginning of spring.
0:36
After months of confinement underground,
0:39
she toboggins down the slope. Perhaps to
0:42
clean her fur, perhaps for sheer joy.
1:01
Her cubs gaze out at their bright new
1:03
world for the very first time.
1:08
The female calls them. But this steep
1:11
slope is not the easiest place to take
1:14
your first steps.
1:29
But they are hungry and eager to reach
1:31
their mother, who's delayed feeding them
1:34
on this special day. Now she lures them
1:37
with the promise of milk, the only food
1:39
the cubs have known since they were
1:41
born, deaf and blind beneath the snow
1:44
some 2 months ago.
1:49
Their
2:02
mother has not eaten for 5 months and
2:06
has lost half her body weight. Now she
2:09
converts the last of her fat reserves
2:11
into milk for her cubs.
2:32
The spring sun brings warmth, but also a
2:36
problem for the mother. It starts to
2:39
melt the sea ice. That is where she
2:42
hunts for the seal she needs to feed her
2:45
cubs. and she must get there before the
2:47
ice breaks up.
2:53
For now though, it's still -30° and the
2:56
cubs must have the shelter of the den.
