Induction of marking behavior in wild red foxes (Vulpes vulpes L.) by synthetic urinary constituents
- 82 Downloads
A control aqueous solution containing alcohol and polyethylene glycol, and a test solution with the addition of a mixture of eight volatile synthetic compounds identified in red fox urine, Were alternately placed on man-made mounds of fresh snow during January and February, the foxes' courtship season. The foxes preferentially marked those mounds treated with the test solution in the two experimental areas (P < 0.05 and <0.0001). It is concluded that one or more of the volatile substances induces mound marking in this species.
