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.

Nonrandom territory occupancy by nesting Gyrfalcons (Falco rusticolus)
Arctic Science, 2019 We know little regarding how specific aspects of habitat influence spatial variation in site occupancy by Arctic wildlife, yet this information is fundamental to effective conservation.

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.

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.

Predator-prey feedback in a gyrfalcon-ptarmigan system?
, 2017 Specialist predators with oscillating dynamics are often strongly affected by the population dynamics of their prey, yet they do not always participate in a predator-prey cycle.

Avian influenza overview September–November 2025
EFSA Journal, Volume 23, Issue 12, December 2025.Abstract Between 6 September and 28 November 2025, 2896 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (442) and wild (2454) birds in 29 countries in Europe. The magnitude and geographical extent of these detections were unprecedented for this time of the year, particularly in wild birds.
