The response of free-living beavers (Castor canadensis) to castoreum and some of its components was determined through a series of field bioassay experiments in southeastern Ohio. Beavers responded to test scents containing castoreum and the neutral and phenol components but not the carboxylic acid and amine components. Urine from the bladder did not attract beaver, whereas urine after it passed the castor sacs and mixed with the contents of the castor sacs was an attractant. No seasonal difference characterized the response to castoreum, and the response to castoreum from adult male and female beavers was not different. The function of odor profiles of beaver and scent mounds are discussed.
