, 2022 To explicitly root our phylogenetic tree, we mined our RAD loci’s homologous genomic bits from the publicly available reference genome of Falco peregrinus (assembly: GCA_001887755) and Falco biarmicus (assembly: GCA_023638135).

Journal of Zoology, Volume 327, Issue 3, Page 236-247, November 2025.We used high‐precision diet estimates from nest cameras to estimate amino acid‐specific trophic discrimination factors (TDFs) for gyrfalcon nestlings and compared these against TDFs for other taxa from the literature. TDFs for trophic amino acids in gyrfalcon were lower than values that have typically been used to estimate trophic position.

The Sustainable Trapping of Falcons – is It Possible in Russia and Other CIS Countries?
Пернатые хищники и их охрана, 2016 This article was prepared according on the analysis of the situation with the poaching and smuggling of falcons (Gyrfalcon Falco rusticolus, Saker Falcon F. cherrug and Peregrine Falcon F. peregrinus) in CIS countries in 2006–2015.

Diet of the Gyrfalcon (Falco rusticolus ) in Northern Fennoscandia.
Gyrfalcons and Ptarmigan in a Changing World, 2011 —the Gyrfalcon is a circumpolar, arctic and resident raptor in Fennoscandia and is totally dependent on only one or two ptarmigan species, the Willow Ptarmigan (Lagopus lagopus) and rock Ptarmigan (Lagopus muta), for food over half of the year. the diet of the Gyrfalcon has been studied in many parts of its range in earlier decades, but recently only ...

Ibis, Volume 167, Issue 4, Page 1053-1064, October 2025.GPS tracking has enabled significant advances in the study of animal movements such as migration and habitat use. However, GPS devices can affect the behaviour of tagged individuals, especially for flying animals such as birds, and may ultimately impair their reproduction and/or survival.

Climatic variation affects seasonal survival of an alpine bird species
Wildlife Biology, Volume 2025, Issue 4, July 2025.Mountains are particularly exposed to climate change, and empirical studies have shown that montane bird species are highly sensitive to the ongoing changes. Modelling mortality risks under climatic variation will give insight into species‐specific sensitivity. Willow ptarmigan Lagopus l.

No support for solar radiation as a major evolutionary driver of malar stripes in falcons
Journal of Avian Biology, Volume 2025, Issue 3, May 2025.The malar stripes of falcons (Falco spp.) are often hypothesised to function by reducing the amount of solar glare reflected into the falcon's eyes while hunting, thereby aiding foraging efficiency in bright conditions. This ‘solar glare hypothesis' is supported by intraspecific trends in peregrine falcons Falco peregrinus, in which populations ...

Southern Extension to the Breeding Range of the Gyrfalcon, Falco Rusticolus, in Eastern North America [PDF]
, 1995 We report the observation of four gyrfalcon (Falco rusticolus) nests and several adults south of the previously recognized southern limit of the species\u27 breeding distribution in eastern North America.
