Ans: Both fisher and bobcat sightings in the eastern Finger Lakes, according to Scott Smith, regional wildlife biologist for the DEC, are likely animals invading from established populations in the Adirondacks and Catskills.    Fisher sightings are more common in central New York's southern region and are most likely the consequence of individuals spreading north from Pennsylvania, where they were reintroduced in the mid-1990s. Bobcats, according to Smith, have lived in the area longer than fisher and are more common and plentiful. Both species are effectively reproducing, and neither can currently be hunted or trapped in the area.
