Pair bonds during the annual cycle of a long-distance migrant, the Arctic Tern (Sterna paradisaea) [PDF]

open access: diamondAvian Research, 2021
Background The extent to which pairs remain together during the annual cycle is a key question in the behavioural ecology of migratory birds. While a few species migrate and winter as family units, for most the extent to which breeding partners associate

Changes in organ size and nutrient reserves of arctic terns (Sterna paradisaea) breeding near a High Arctic polynya [PDF]

open access: goldArctic, Antarctic, and Alpine Research, 2020
The arctic tern (Sterna paradisaea) is a ubiquitous migratory seabird of the High Arctic, currently thought to be in decline in most of the circumpolar world, but surprisingly little is known of its biology at high latitudes.

New records and a review of the distribution of the Arctic Tern Sterna paradisaea Pontoppidan, 1763 (Aves: Sternidae) in Brazil [PDF]

open access: yesCheck List, 2012
We report new records of the Arctic Tern Sterna paradisaea Pontoppidan, 1763 for the coast of Rio Grande do Sul, southernmost Brazil. Birds were in first alternate plumage, apparently overwintering in the region.

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

open access: green, 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.

Population Trends of Gulls and Arctic Terns Nesting in the Belcher Islands, Nunavut

open access: bronze, 1999
. Little information exists on the population trends of gulls and terns nesting in the Arctic. In 1997, we surveyed the number of glaucous gull (Larus hyperboreus), herring gull (Larus argentatus), and arctic tern (Sterna paradisaea) nests on the Belcher

Blood hemoglobin content and metabolic performance of Arctic Tern chicks Sterna paradisaea

open access: green, 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.

Postbreeding dispersal and staging of Common and Arctic Terns throughout the western North Atlantic

open access: greenAvian Conservation and Ecology, 2017
In the western North Atlantic, Common (Sterna hirundo) and Arctic (S. paradisaea) Terns are sympatric at breeding colonies but show divergent migration strategies to coastal areas of South America and pelagic regions of the Antarctic, respectively ...

Arctic tern migration : from individual variation to common flyways of trans-equatorial seabirds

open access: green, 2021
Arctic terns are iconic seabirds, famous for annual migrations between the Arctic and Antarctic. Recent assessment suggests they are one of the most vulnerable seabirds to climate change. Its wide geographical range hinders the detection of hazards faced

Variations in the Reproductive Activities of Arctic Terns at Churchill, Manitoba

open access: bronze, 1972
Nest locations and contents were observed in 16 colonies over a 3-year period. Laying times correlated with spring temperatures, but not with colony size. Clutch size increased with time between ice breakup and laying onset.
