Population status

Mute Swan
(Cygnus olor)

Mute Swan populations have increased dramatically in both numbers and distribution since their introduction in North America. The first breeding record of feral Mute Swans in southern Ontario was in 1958. In the mid-1960s and 1970s, Mute Swans began colonizing the lower Great Lakes and the population has been expanding ever since (Petrie and Francis 2003). In British Columbia, Mute Swan numbers have been steadily increasing since the late 1990s, primarily on southern Vancouver Island and in the Fraser River delta.
