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.
Fisher are solitary animals throughout most of the year, although snow tracking often indicates that two or more fishers will hunt in parallel patterns. Activity is mostly at night, although it appears that fishers hunt frequently during daylight hours in wilderness habitats.
