Site tenacity of the Long-tailed Skua Stercorarius longicaudus—a study of the population at Stekenjokk
The breeding site tenacity of a population of Long-tailed Skuas Stercorarius longicaudus at Stekenjokk in the northern part of Jämtland was studied in an area of 27 km2 between 2001 and 2006. At least one bird in a pair was ringed for identification. The Long-tailed Skua had pronounced breeding site...
