Ross’s Gull (Rhodostethia rosea) Breeding in Penny Strait, Nunavut, Canada

We found a small, previously undiscovered breeding colony of Ross’s gulls (Rhodostethia rosea) in Nunavut, Canada, approximately 80 km from a previous colony location occupied during the 1970s. The birds nested in association with arctic terns (Sterna paradisaea). The collective observations from th...

Description
Summary:We found a small, previously undiscovered breeding colony of Ross’s gulls (Rhodostethia rosea) in Nunavut, Canada, approximately 80 km from a previous colony location occupied during the 1970s. The birds nested in association with arctic terns (Sterna paradisaea). The collective observations from this region of the High Arctic suggest that Ross’s gulls may move colonies each year, or that colony occupation is intermittent. Nous avons repéré une petite colonie de reproduction de mouettes rosées (Rhodostethia rosea) non découverte jusqu’à ce moment-là au Nunavut, au Canada, à environ 80 kilomètres de l’emplacement d’une autre colonie occupée dans les années 1970. Les oiseaux nichaient avec des sternes arctiques (Sterna paradisaea). Les observations collectives de cette région de l’Extrême-Arctique laissent supposer que les mouettes rosées peuvent changer de colonie chaque année ou que l’occupation des colonies est intermittente.
