Beavers feast on new green shoots, baby bison take their first faltering steps and grizzly bear cubs emerge from dens to explore this new green world. But spring is also a perilous time.

Only the toughest will survive.

Rodents like rats, mice and squirrels are the most numerous mammals on the planet. This programme reveals how, with their constantly growing, chisel-sharp front teeth, they are specialists in breaking into seeds.
