Home Range and Habitat Selection of the Endangered Red Goshawk (Erythrotriorchis radiatus) Across Australia's Tropical Savannas

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We used long‐term GPS tracking to quantify home‐range size and habitat selection of the endangered Red Goshawk across tropical savannas of northern Australia. Red Goshawks occupied extensive overall home ranges, with well‐defined core ranges centred on nest sites.

Resident and Migratory Falcons' Breeding Phenology and Productivity Respond Differently to Weather and Climate Change Across the Arctic

Global Change Biology, Volume 32, Issue 8, August 2026.
Climate change is altering breeding phenology and productivity of peregrine falcons and gyrfalcons across the circumpolar Arctic. Long‐term monitoring shows that responses vary among study areas and Arctic regions, with some populations advancing hatch dates while others show weaker or contrasting trends, highlighting spatially variable effects of ...

Distance sampling: comparing walked transects and road transects for rock ptarmigan densities and population trends

Wildlife Biology, Volume 2026, Issue 4, July 2026.
We compared population trends for rock ptarmigan Lagopus muta densities (2003‒2019) derived from walked transects and driven road transects in Mosfellsheiði and Slétta in southwest and northeast Iceland, respectively. The walked transects were laid out according to a random rule.

The caliph and the falcons: a ninth‐century history from Iceland to Iraq

Early Medieval Europe, Volume 34, Issue 2, Page 299-322, May 2026.
In the late ninth and early tenth centuries, an extraordinary number of falcons were given to the ʿAbbāsid caliphs in Baghdad, many of which were white. Gifts from competing dynasties in the northern provinces of the Caliphate, at least some of these birds were almost certainly gyrfalcons from near the Arctic Circle.

Sedimentary Metagenomics Reveal Avian Community Transitions From the Last Glacial Maximum to the Holocene

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We used sedimentary ancient DNA shotgun metagenomics to reconstruct past bird communities in northern high‐latitude environments. By using long time series and data collected across a large environmental gradient, we contributed in a unique and explorative way to the understanding of palaeoecological dynamics between birds and their habitat on the ...

Behavioural responses of a gamebird to human encounters across the hunting season

Wildlife Biology, Volume 2026, Issue 2, March 2026.
We examined the behavioural adaptation of rock ptarmigan Lagopus muta in response to human encounters across the hunting season. We conducted disturbance experiments in two different parts of the species' range, in subarctic (Iceland) and in alpine (Italy) habitats.

Evolution and Climate Adaptation in Eurasian Gyrfalcon Populations

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This reports the influence of past, current and future Arctic climate change to the evolution of Eurasian gyrfalcons (Falco rusticolus), and reveals that its current evolutionary potential is insufficient to cope with the ongoing Arctic warming. ABSTRACT Climate change is considered a key driver for shaping ecological and evolutionary processes of ...

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 ...
