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!
To add to my previous post I thought I’d share one of the more impressive series of images from a den thus far;
We believe the Red-tailed Hawk you can see entering and exiting the upper left of frame in this series was attempting to steal the prey item being carried by female 199B9 (center frame) to her natal den in April 2011. Whatever the reason, she survived unscathed and went on to occupy 2 maternal dens through the 2011 season before her VHF transmitter finally failed.

With the belated and thus far underwhelming winter storms making an appearance recently a few of us have found ourselves with time on our hands away from the field. In light of this situation the ever industrious Aaron has, among other assignments, set us to work organizing a digitalized mountain of trail camera pictures.
As a (more?) naïve youth I used to quite enjoy going through these pictures, then I came to work in bear country…needless to say, the novelty has worn a little thin. For the uninitiated; it is a favorite pastime of black bears to find, wander around in front of and then try to eat trail cameras, this can become a little tedious to watch the 10th or 100th time you see it. Nonetheless, we do get to see some of the more reclusive local residents going about their business too.
I thought I’d share a few recent favorites to add a little color…then I realized they were all night shots.
