Hi Folks,
I find this Fisher Release Program interesting but than again I have always found wildlife interesting. When I was a young guy I always wanted to work with small wildlife and thought about going to school and becoming a Biologist but than girls came along, I quit school and got married young and became a trapper.
In 1989 I has asked if I could teach a Biologist how to trap coyotes for his Urban coyote study that he was going to do in the Seattle / Bellevue area. It was a two year program. I spent about sixty hours with him and we trapped and radio-collared a dozen coyotes and let them go. At the time I was also trapping a lot of coyotes for a Rancher so I gave him the carcasses so he could work on blood samples, stomach contents etc. I also show him what coyote dropping looked like so he had an idea.
He picked up 900 pieces of scat in four months. Hair doesn't dissolve so they can see what the animal is eating. In 900 pieces of scat 1/3 of the coyote diet was mice & rats and 2/3 was (Your going to love this) "house cats" all in the Urban / Metropolitan areas. They also eat a lot of fruit such as blackberries, apples and plumbs.
This fisher research is going to DNA now beside the hair samples. What is interesting about this research project is that they have a "Dog Handling Group". Their job is to have the dogs run out and find "Fisher Poop." They pick it up and give it to the researchers so they can find out what the fisher is eating. I'm thinking its back to the hair samples. They have also found several Fisher dead that were killed by predators. I asked the question to one of the Leading Researchers and here is what she said:
We know that bobcats and one cougar killed some of our female fishers because we were able to get on some of the kills soon enough that swabs of the wound sites contained enough saliva, that the lab could get DNA and identify the predator - kind of a fisher CSI. Many of the kills, however, were too far gone for us to ID the predator - so some may have been take by coyotes, but we were never able to document that.I am planning on staying in touch with these people and writing about this Fisher Research in our upcoming issues in our newsletter. Stay tune I think this reintroduction and release of the Fisher will be a positive issue for us trappers.
