Oregon Department of Fish and Wildlife Release Fisher After GPS Collaring


Oregon Department of Fish and Wildlife’s (ODFW) Wildlife Research staff in southwest Oregon captured, collared and released a fisher (Pekania pennanti), a carnivorous mammal native to North America.

The short video of the fisher release is very entertaining as the wily critter leaps over the camera to the astonishment of field staff. So far, the video has had more than 1.6 million Views, 10,000+ Likes and was viewed by people in almost 50 different countries.

The subadult male in the video was fitted with a GPS collar in December 2023 to collect locality data that will help ODFW to understand home range sizes, movement rates, causes of mortality, habitat use and connectivity of fisher in Oregon.

GPS collars are fitted with enough room to support growth and biologists don’t collar juvenile animals. The material of most fisher collars is nylon which will eventually wear down as the animal moves through brush. Additionally, leather breakaway strips are added to provide a weak point that will fray and release after a period of time or if it happens to get caught on something. Collars can also be removed if the animal is recaptured.

Fisher are an Oregon Conservation Strategy Species found in forests and riparian corridors and known for preying on porcupines. In Oregon, they are found in the Klamath, Coast and Cascade Ranges. The Coast Range population is native while the Cascade Range population is from reintroductions done in the 1960s and 1980s from British Columbia and Minnesota.
