Population status

Brant
(Branta bernicla)

Recent estimates of the Atlantic population suggest a population of about 200,000 birds, according to Lincoln estimates. The number of Eastern High Arctic Brant is estimated by counts on the wintering grounds; recent estimates suggest a population of about 35,000 geese. Black and Western Arctic populations are assessed during winter surveys where it is difficult to separate the two types of Brant. The population estimate is therefore unavailable. The Atlantic Brant population, as well as the Eastern and Western High Arctic populations, are considered to be at acceptable levels, while the Black Brant's population is considered to be data deficient. Detailed information on the population status of waterfowl species is available in the Population Status of Migratory Game Birds in Canada report (summarized version).
