About the episode
Spring marks the start of an epic race for life where timing is everything; trees explode with blossom and mornings fill with the magical chorus of bird song. Long-tailed tits frantically build nests, while in our oceans, seahorses sway to a graceful courtship dance.
As we celebrate Easter, a stoat mother hunts the young rabbits to feed her own playful young.
As spring becomes summer, Guillemot chicks leap from their cliffs to begin life at sea, and this year's young prepare for life alone.
Spring is the second of four programmes making up The Great British Year, a season-by-season exploration of how wildlife adapts across the calendar.
Spring is first shown on BBC One at 9.00pm, Wednesday 9th October 2013.
