Biometrics and colour forms of chicks of common terns and arctic terns

Ringing & Migration, 1984
Methods of distinguishing the chicks of Common and Arctic Terns based on measurement of tarsus length and on the colours of the dorsal down and the belly down are described. The variation of tarsus length with age was investigated by relating it to bill length, to mid‐toe length, and to body weight.

Annual survival of Arctic terns in western Iceland

Polar Biology, 2020
Many seabird species in the North Atlantic region have shown considerable declines in their populations during recent decades. One such species is the Arctic tern (Sterna paradisaea), a small seabird which migrates farther than any other seabird each year and whose global population is thought to be in decline. We used banding data of chicks and adults,

Common Tern Sterna hirundo and Arctic Tern S. paradisaea hybridization produces fertile offspring

Seabird Journal, 2016
This study provides the first molecular evidence for hybridization between Arctic Terns Sterna paradisaea and Common Terns S. hirundo. We studied a mixed pair (P1; male Arctic Tern and female Common Tern) and its offspring on Penikese Island, Massachusetts, USA in 2007–2015.

Sexing Arctic Terns in the Field and Laboratory

Waterbirds, 2004
Abstract We examined sexual size dimorphism of Arctic Terns (Sterna paradisaea) from a breeding colony in northeastern North America. Each bird was sexed using DNA extracted from feather pulp. Body morphometrics recorded included mass, natural wing chord, head-bill, tail fork, culmen, depth of bill at the gonys, and tarsus.

Breeding biology of Arctic terns (Sterna paradisaea) in the Canadian High Arctic

Polar Biology, 2017
The Arctic tern (Sterna paradisaea) is a well-known polar seabird which breeds around the circumpolar Arctic, and which undertakes the longest known annual migration of any organism. Despite its familiarity, there is little information on its breeding biology in the High Arctic, an important baseline against which future studies of climate change ...
