Willow ptarmigan Lagopus l. lagopus is a popular game bird which fluctuates in abundance. The causes of these fluctuations, however, remain controversial, but several studies have emphasised the effect of predation. Predation not only reduces the number of breeding birds, but does it in such a way t...
