Black grouse (Tetrao tetrix) : These dramatic wild game birds are found on moorland especially in Scotland and some areas of Wales but also in North eastern England. In spring the males gather together at traditional sites known as leks where they display : fanning their tails, strutting and bowing, occasionally leaping in the air and attcking one another to demonstrate their dominance. An early morning start is needed to see this strange ritual but the sight and sound of the lek makes for a truly unforgettable experience.
