    Description

    The goal of this workshop was to discuss the development of a strategy to determine the status and assess trends of nocturnal raptor species (i.e., nocturnal owls) in Canada and the USA. A strategy for diurnal raptor species was initiated at a workshop in Boise, Idaho in August 1996. The results of these workshops will form the basis for developing the North American Raptor Monitoring Strategy. This owl workshop focused on nocturnal survey techniques for inventorying and monitoring owls.
