Immature Long-tailed Skuas Stercorarius longicaudus in Swedish Lapland in 2009
Between 12 and 27 June 2009, 10 immature Long-tailed Skuas Stercorarius longicaudus were recorded in breeding areas in Swedish Lapland. Based on plumage characters, these were aged as 3rd calendar year birds. The fraction of immatures in the total number of aged birds was 4–10%, which seems to be in...
