COSEWIC Update Status Report on the Roseate Tern in Canada 1999
Assessment Summary – October 1999
Common name: Roseate Tern
Scientific name: Sterna Dougallii
Reason for designation: The number of mature individuals in Canada is fewer than 250; rescue through immigration of United States birds is unlikely since the species is also endangered in New England. The primary factor that limits the population is predation of eggs and hatchlings, and, to a lesser extent, adult birds.
Occurrence: Quebec, New Brunswick and Nova Scotia
Status history: Designated Threatened in April 1986. Status re-examined and designated Endangered in April 1999. Endangered status re-examined and confirmed in October 1999. Last assessment based on an existing status report.
