Likely a little belated in most instances (and possible early for a few others), but mid-March to early-April is the time when fishers’ give birth to their kits. Our oldest on-air female just turned 8 years old, while the oldest male we are tracking turned 9!
This is a busy time of year for us on the ground. We try and locate the den-sites for all females who are old enough to have kits. In addition, we set up and maintain motion-censored cameras at all of the dens, attempting to get a glimpse into activities around the den as well as detect kits once a female chooses to move to another den.
This year, we are tracking 18 females who could potentially den and have kits. Thus far, 13 individuals are exhibiting behavior consistent with denning (staying in the same tree over multiple days). In addition to females giving brith, spring is also the time of year when breeding occurs. Males are busy roaming around trying to find the females, and often end up at their dens. As such, our camera’s have been takings lots of really interesting photos.
I made a “motion picture” from the photographs of one remote camera over the course of a few days at a natal den, which you can view HERE. Also below are a few pics from various dens so far. Enjoy!
