The rock ptarmigan (Lagopus muta) is a common breeding bird in Iceland and the population shows fairly regular 10-year cycles. Independent of the cycle the population has been declining 4% annually for the last decades and the amplitude is markedly reduced. In this study two questions are addressed. One is whether generalist predators can cause the dampening of the population cycle and the decline of the population. The other is whether there is an age related difference in chick production, which is information needed to refine a population model of the ptarmigan in Iceland. Hens were trapped in two areas in Iceland, one in the north-east in 2009 and 2010 and the other close to the city Reykjavík in the south-west in 2007 and 2008. Two age...
