"Red Grouse(Lagopus lagopus) Family Tetraonidae
The red grouse is a medium-sized game bird. It has a plump body, a short tail and a lightly hook-tipped bill. It is reddish-brown, with its legs and feet covered in pale feathers. Birds breed in the UK in the uplands of the north and west and are resident all year round, travelling very little in their lives. The population is declining, perhaps linked to diseases and the loss of heather moorland.
The best place to see this bird is on upland heather moors, when is suddenly rockets up from the heather when disturbed to fly off with fast-whirring wingbeats. Can be seen all year round, feeding on heather, seeds, berries and insects."
