Some observations on the natural history and behaviour of the Canada Lynx, Lynx canadensis

Abstract

We made observations of Canada Lynx (Lynx canadensis) natural history during a long-term study of lynx population dynamics in southwest Yukon. We found evidence of adult lynx mating during Snowshoe Hare (Lepus americanus) population lows. We also found evidence of adult lynx litter sizes as large as eight and of adult and yearling lynx giving birth to kittens as much as six weeks later than normal, during hare highs. We document one instance in which a late-born litter of five survived to April when hares were abundant. We present evidence to suggest that some female lynx may lose their litters shortly after parturition during periods of food shortage. The above adaptation allow lynx the flexibility to respond demographically to changes in food supply faster than other species its size. We present evidence to suggest that the bond between related female lynx continues into their adult lives, as in other fields.
