The wildlife programme returns for its seventh series, this time looking at nature in the Cairngorms.
This week Chris Packham, Michaela Strachan, Gillian Burke and Iolo Williams attempt to observe crested tits, pine martens, red squirrels and golden eagles. The show will also be delivering something else: warnings to sensitive viewers due to some of the more violent scenes that has been shown in previous series.
Winterwatch is on at 20.00 on BBC Two with further coverage on the Red Button.
