Individual-Level Responses to Rapid Climate Change in Common Terns (Sterna hirundo) and Arctic Terns (Sterna paradisaea) [PDF]

open access: yes, 2023
This study examines fine-scale environmental changes and intraspecific variation in the diet and foraging behavior of two seabirds in the Gulf of Maine, one of the fastest-warming regions of the ocean.

Blood Hemoglobin Content and Metabolic Performance of Arctic Tern Chicks Sterna paradisaea

open access: yesJournal of Avian Biology, 1996
This study was designed to determine whether the development of an increased aerobic capacity (increased potential for oxygen uptake) during the initial growth stages of hatchlings is associated with an increase in blood hemoglobin content. We measured the resting (at thermoneutrality) and maximum (cold induced)b oxygen uptake of Arctic Tern chicks ...

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

open access: yes, 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.

The comparative breeding ecology of sympatric common and arctic terns in N.E. England [PDF]

open access: yes, 1999
The life-history traits of two sympatric seabird species, the Common Sterna hirundo and Arctic Tern S. paradisaea, and the flexibility of these traits in relation to short and longer term changes in environmental conditions were measured at Coquet Island,

Characterizing partial migration using GPS tracking: high individual consistency in greylag geese

open access: yesJournal of Avian Biology, Volume 2026, Issue 5, September 2026.
Migration is a critical ecological strategy throughout the animal kingdom and can be either fixed or flexible at the species, population, and individual levels. In partially migratory species, where only some individuals migrate, individuals may show consistency in their migratory behaviour. Greylag geese Anser anser are considered partially migratory,

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

open access: yesPolar 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

Pre-breeding foraging ecology of three tern species nesting in the Gulf of Maine

open access: yesAvian Conservation and Ecology, 2022
A variety of seabird species migrate annually from wintering grounds in the Southern Hemisphere to the Gulf of Maine, USA to breed and raise their young.

A half century of monitoring reveals contrasting survival responses of Icelandic seabirds to climate and fisheries pressures

open access: yesIbis, Volume 168, Issue 3, Page 950-971, July 2026.
Seabirds serve as key indicators of marine environmental changes, with adult survival being a critical parameter for assessing population health. Iceland hosts some of the largest seabird populations in the North Atlantic, making it a valuable location for studying long‐term trends in seabird demographics.
