Cougars range in colour from buff to grey, to brown, and a variety of shades in between. Their long tail is a distinctive feature. Solitary by nature, they constantly patrol their home territories and prefer to live in remote woodlands and highlands. Deer, moose, snowshoe hare, beaver, birds, mice and frogs make up the bulk of the cougar's diet.
Despite many reported sightings, the last documented evidence of the cougar in Atlantic Canada was around 1930. The eastern subspecies was recently changed from Endangered to Data Deficient and receives full protection in both Nova Scotia and New Brunswick.
