Migratory Birds Advance Spring Arrival and Egg-Laying in the Arctic, Mostly by Travelling Faster. [PDF]

Glob Chang Biol
A warming climate is affecting the phenology of life on earth, including when birds migrate and start breeding. We show that earlier arrival is a general pattern also for birds travelling to the Arctic region, arriving earlier when snow melts early as well as with time.

A photographic approach to monitor spatial dynamics and population trends of Arctic Tern colonies in two touristic bird watching spots in the Westfjords, Iceland

Avocetta
This study examines the population dynamics and spatial distribution of Arctic Terns in two tourist sites in Iceland's Westfjords: Vigur Island and Súðavík. In 2023, counts revealed 458 terns in Súðavík and 991 in Vigur. We propose a monitoring approach

Conservation implications of shifting habitat use in migrating insects: Selection patterns in a threatened damselfly show that season‐specific actions are needed

Insect Conservation and Diversity, Volume 19, Issue 4, Page 769-781, July 2026.
Well‐preserved heathlands of NW Italy are the main overwintering habitat of Sympecma paedisca, while grassy margins in farmland are used only in summer and are avoided from autumn onwards. Grassy margins in farmland act as corridors during the species' migrations between its breeding (ricefields) and overwintering (lowland heathlands) grounds ...

Changes in Isotopic Niches across Stages of the Annual Cycle in the Arctic Tern (Sterna paradisaea)

Arctic, 2018
 Arctic Terns (Sterna paradisaea) are iconic seabirds of polar latitudes, whose successful reproduction is thought to depend on local food supplies near breeding colonies.

Citizen science reveals host‐switching in louse flies and keds (Diptera: Hippoboscidae) during a period of anthropogenic change

Medical and Veterinary Entomology, Volume 40, Issue 2, Page 305-322, June 2026.
A study of louse flies in the United Kingdom, Isle of Man, and Ireland found 212 different interactions between Hippoboscidae and their hosts, of which 70 were previously unrecorded. No louse flies were found on aquatic species of birds. Host‐switching to gulls (Laridae) has occurred during a period in which these species have started relying on ...

Hypotheses and tracking results about the longest migration: The case of the arctic tern

Ecology and Evolution, 2019
The arctic tern Sterna paradisaea completes the longest known annual return migration on Earth, traveling between breeding sites in the northern arctic and temperate regions and survival/molt areas in the Antarctic pack‐ice zone.

Physiological characteristics of arctic tern Sterna paradisaea chicks in relation to egg volume

Polar Research, 1997
The effect of egg volume on body mass, body composition and growth rate in Arctic tern Sterna paradisaea chicks was studied at Ny-Alesund, on Svalbard (78°55'N, 12°00'E), in order to investigate whether differences in egg size influence the physiological characteristics of the hatchlings. The relative content of yolk and albumen in eggs did not vary in

How a Winner Can Also Be a Loser? At‐Sea Vulnerability of a Critically Endangered Endemic Seabird to Climate Change

Journal of Biogeography, Volume 53, Issue 4, April 2026.
ABSTRACT Aim The last decades have been marked by a global decline of many migratory species, and predictions are even more alarming when climate change is considered. We investigated the migration patterns and marine habitat selection processes of a critically endangered endemic seabird of the tropical western Indian Ocean, and projected future ...
