Mercury in Feathers of Swedish Gyrfalcons,Falco Rusticolus, in Relation to Diet
Bulletin of Environmental Contamination and Toxicology, 1984The gyrfalcon (Falco rusticolus) is mainly a resident bird breeding in mountain areas in Fennoscandia. The population (estimated to 300-500 pairs) probably fluctuates according to the presence of willow grouse (Lagopus lagopus) and ptarmigan (Lagopus mutus). Little is known about pollutant levels in Fennoscandian gyrfalcons.

Plasma chemistry reference values in the gyr falcon (Falco rusticolus)
Comparative Clinical Pathology, 2013Blood samples were collected from 102 clinically healthy gyr falcons (Falco rusticolus) over a time period of approximately 3 years as part of routine examination proce- dures. Standard blood chemistry analyses were carried out to establish normal reference values for the species. Plasma chemistry analyses included alkaline phosphatase (ALP), am- ylase,

Persistent organochlorine levels in six prey species of the gyrfalcon Falco rusticolus in Iceland
Environmental Pollution, 2001Our previous investigations have revealed very high levels of organochlorines (OCs) in the Icelandic gyrfalcon Falco rusticolus, a resident top predator. We now examine six potential prey species of birds, both resident and migratory, in order to elucidate the most likely route of the OCs to the gyrfalcon.
