This year Lynx inventory is approaching its end, even if all family groups in the county have not been found and documented. In early March starts the rut and then it becomes more likely that the two tracks together is all about a pair of lovers, than it would be a female with a cub.
Early in the season, and if the snow is wet, which give clear footprints, you can often tell the difference between the adult female's paw prints compared to cubs, which is slightly smaller. The picture shows tracks from a lynx female and cub. ( cub was submitted at the prey while the female walked away for a moment.) Unlike dog feets, cat's feets are asymmetric (like humans feets), so it is easy to distinguish between right and left footprints.
One winter night in the late eighties, I was privileged to study a female lynx and her cub. Under cover of darkness, they visited a roe deer, the female killed a few days earlier. It was an amazing experience to see the shy cats, only a few feet away and in a few hours time. Although I clearly saw their big soft feet trampling the snow-covered ground I did not hear the slightest sound, they moved silently. However, I was very surprised by how loud conversation was between mother and baby, the contact call was a very sharp and crisp sound.
