Tim writes: Red Grouse (Lagopus lagopus) often defend a territory all through winter, in which the pair will breed in spring. Birds that haven’t managed to discover a territory type a nomadic flock and can take up any vacancies if any territory-holders die. However over the previous couple of days I’ve observed that each one the traditional territories seem to have disappeared and there may be now one massive tremendous-flock of Red Grouse. I’ve counted the birds from pictures and this flock exceeded 80 birds although this one simply reveals a part of that flock. This flocking behaviour has coincided with chilly, snowy climate although it surprises me that they seem to have given up their territories as they’re used to snow and chilly temperatures. Additionally their smaller relative Ptarmigan (Lagopus mutus) survives the winter on high of Scottish mountains and is even resident on Svalbard, a whole bunch of miles north of the high of Norway. This {photograph} was taken on 12 February excessive on the Peak District Moors in West Yorkshire.
