Autumnwatch

Chris Packham, Michaela Strachan and Gillian Burke have travelled to New Hampshire as billions of trees across New England turn into a riot of yellows, reds and golds.

Chris and Michaela are live from the beautiful Squam Lake in New Hampshire. Gillian gets up close with one of New England's smallest owls, the saw-whet.

Michaela has been on a moose mission, finding out about a tiny but deadly enemy of these massive beasts, and Gillian is looking for red efts in the leaf litter - a brightly coloured newt that comes out in damp conditions.

The incredible migration of the monarch butterfly; a swirling tornado of tree swallows in Connecticut; in Boston, gangs of turkeys roam the streets driving some residents to distraction.
