Ecology of the gyrfalcon (Falco rusticolus) in central Scandinavia: diet and feeding behaviour in fluctuating ptarmigan abundances

Due to climate change global temperatures are rising, which is particularly pronounced at higher latitudes. Therefore, it is important to investigate the resilience of northern ecosystems to these environmental changes.

Gyrfalcon Falco rusticolus post-glacial colonization and extreme long-term use of nest-sites in Greenland

, 2009
Gyrfalcons Falco rusticolus use the same nest-sites over long periods of time, and in the cold dry climate of Greenland, guano and other nest debris decay slowly.

First Record of Nestling Relocation by Adult Gyrfalcons (\u3cem\u3eFalco rusticolus\u3c/em\u3e) Following Nest Collapse

, 2017
Nest collapse has been documented in many bird species, with little discussion of adult behavior following collapse. We present evidence of a partial collapse of a Gyrfalcon (Falco rusticolus) nest during the nestling period and the subsequent adult ...

Gyrfalcon Diet During the Brood Rearing Period on the Seward Peninsula, Alaska, in the Context of a Changing World

, 2016
As climate change impacts increase so does our need to understand their effects on ecosystem dynamics. I studied Gyrfalcon (Falco rusticolus) diet during the brood rearing period to improve our knowledge on dietary habits during nesting, and provide ...

Genetics of plumage color in the gyrfalcon (Falco rusticolus): analysis of the melanocortin-1 receptor [PDF]

, 2012
Genetic variation at the melanocortin-1 receptor (MC1R) gene is correlated with melanin color variation in a few reported vertebrates. In Gyrfalcon (Falco rusticolus), plumage color variation exists throughout their arctic and subarctic circumpolar ...
