These terms describe when an animal is most active: 1  Nocturnal - active primarily at night. 2  Diurnal - active primarily during the day. 3  Crepuscular - active primarily during both dawn and dusk. Many animals that are casually referred to as nocturnal are actually crepuscular.  Metaturnal - active part of the day and part of the night.
Fishers prefer large areas of dense mature coniferous or mixed forest and are solitary animals. They are mainly nocturnal, but may be active during the day. They travel many miles along ridges in search of prey, seeking shelter in hollow trees, logs, rock crevices, and dens of other animals.
