A Picky Predator and Its Prey: How Snow Conditions and Ptarmigan Abundance Impact Gyrfalcon Feeding Behaviour and Breeding Success [PDF]
Ecology and EvolutionSpecies interactions can be altered by climate change but can also mediate its effects. The gyrfalcon (Falco rusticolus) and the ptarmigan (Lagopus spp.) form a predator–prey couple that reflects the dynamics of boreal, tundra, and alpine ecosystems.

Gyrfalcon Prey Abundance and Their Habitat Associations in a Changing Arctic [PDF]
Ecology and EvolutionArctic habitats are changing rapidly and altering trophic webs and ecosystem functioning. Understanding how species' abundances and distributions differ among Arctic habitats is important in predicting future species shifts and trophic‐web consequences ...

First pre-modern record of the gyrfalcon (Falco rusticolus) in north-east Greenland [PDF]
Polar Research, 2019 Gyrfalcon (Falco rusticolus) is the largest falcon in the world. It inhabits a wide range of climate zones in the Northern Hemisphere, from boreal forests in the south of its range to the arid polar deserts of the High Arctic.

Migration, Habitat and Hunting Style Do Not Affect the Malar Stripe of Different Falcon Species. [PDF]
Ecol EvolMigratory strategy, habitat and hunting style do not markedly influence the size and intensity of malar stripes across falcon species, suggesting that other mechanisms, such as thermoregulation or camouflage, also play a role. ABSTRACT The solar glare hypothesis suggests that the malar stripe of a falcon decreases the sun's glare in the eye, possibly ...
