In 1991 and 1992 Common and Arctic Terns differed in chick-feeding and chick-rearing strategies. Arctic Terns favoured smaller prey, primarily crustaceans, for feeding their chicks than did Common Terns. Consequently, Arctic Tern feeding rates were higher. The influence of the tide on food parameters was greater in Arctic Terns.

Common Tern Sterna hirundo and Arctic Tern S. paradisaea hybridization produces fertile offspring
Seabird Journal, 2016This 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.

Dispersal and climate change: a case study of the Arctic ternSterna paradisaea
Global Change Biology, 2006AbstractDispersal is an important evolutionary process that can affect admixture of populations and cause rapid responses to changing climatic conditions due to gene flow from populations at different altitudes or latitudes already experiencing these conditions.

Abstract. Arctic Terns show large variations in colony attendance between breeding seasons, making comparable counts of colony size complex and population status estimates difficult. Here, three areas in two regions of Greenland were surveyed in consecutive breeding seasons between 2002 and 2009.

Nest defence and predator recognition by Arctic tern \kur{(Sterna paradisaea)}
2022In the presented work, I describe the behaviour of Arctic terns (Sterna paradisaea) toward predator species that differ in the threat they represent to them and to their nests. I presented textile dummies of great black-backed gull (Larus marinus), peregrine falcon (Falco peregrinus), common raven (Corvus corax) and common eider (Somateria mollissima),
