The influence of food availability on the breeding effort and reproductive success of Arctic Skuas Stercorarius parasiticus
Territorial attendance, chick growth rate and breeding success of Arctic Skuas Stercorarius parasiticus in Shetland were lowest in the late 1980s when recruitment of Sandeels Am‐modytes marinus in the surrounding waters was poor. The relationships between both fisheries‐based and avian indices of fo...
