Behavior

Sightings of thylacines were usually of solitary animals. Occasional sightings of adult-sized animals together cannot be construed as evidence of pair-bonding, and there is no evidence to support territorial defense of home ranges. Tasmanian wolves were mostly nocturnal but were occasionally observed active during the day.

These vocalizations are not dissimilar in structure to the vocal repertoire of the Tasmanian devil.
