Extralimital reports of cougars (Puma concolor) at the northern limits of t
heir range are rare. We documented at least 21 individual occurrences of co

a between the years 1983 and 2000. Our evidence suggests that, at a minimum
, transient cougars are regular visitors to northern Alberta and the Northw
est Territories.
