These noble members of the deer family were once one of Canada’s most widespread wildlife species, found in over 80% of the country. Today though, their numbers are dropping dramatically—for many herds by more than 90%. The average weight is 55 kilograms to 318 kilograms and their lifespan is 10-15 years. Unlike other members of the deer family, both male and female caribou display antlers for part of the year.
