Just read this today.
a Lynx was live-trapped near here (Kamloops BC, west of the Rockies), 7 yrs ago, they figured it was 2 yrs old. They transplanted it, near Silverton Colorado.
From the tracking info or tag, they figured it had a mate and they had a few offspring, then it disappeared.
Recently a trapper in Alberta caught a tagged Lynx in a snare. This was north of Banff Alberta..
Seems the cat had travelled close to 1200 miles, was getting near where it had started from..
.. less than 300 miles but was still on the east side of the Rockies..
Simply amazing..
