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.

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 Arctic Terns Kill Lemmings

ARCTIC, 2010
Arctic terns ( Sterna paradisaea ) are well known for exhibiting vigorous defense of nests at their breeding colonies. However, in 2008 we observed a previously unreported behavior by terns. We watched chick-rearing adult terns attacking collared lemmings ( Dicrostonyx groenlandicus ), which included repeatedly lifting them into the air and dropping ...

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,
