Mother is after eggs.

0:00:08.920,0:00:11.720
But getting them is not going to be easy.

0:00:32.120,0:00:35.400
The geese will risk their lives to protect their eggs.

0:00:36.640,0:00:37.800
If they lose them,

0:00:37.800,0:00:40.960
they can't produce another clutch this season.

0:00:46.560,0:00:48.880
The fox wins.

0:00:57.600,0:01:01.360
She gives the first eggs to her young pups

0:01:05.040,0:01:07.480
and then heads back for more.

0:01:32.160,0:01:35.320
Some of the eggs, she stashes away.

0:01:38.520,0:01:42.280
They will be food to help her [br]through the coming winter.

0:02:00.680,0:02:02.520
In just three weeks,

0:02:02.520,0:02:06.440
she will steal over 800 eggs from the geese.

0:02:17.320,0:02:20.560
But eating a big egg is not easy

0:02:21.120,0:02:23.160
if one is rather small.

0:02:26.640,0:02:30.200
It's a technique the pups haven't quite yet cracked.

0:02:32.560,0:02:35.640
Mum shows how it's done.
