    Description

    Tape playback of the staccato song of the Boreal Owl (Aegolius funereus richardsoni) proved useful in attracting fledglings of both North American Aegolius species. No Boreal Owl nests were found in 8 hours of daytime searches. However, six Boreal Owls, including three to four fledglings at two locations, one Northern Saw-whet Owl (A. acadicus) fledgling, and an unidentified Aegolius responded to tape playback in 16 hours of systematic surveys during the post-fledging period (15 July to 30 August) of 1992 and 1993 in habitat known to be occupied by Boreal Owls. This method is considerably less costly than other means of documenting breeding by this species and may prove useful for other owl species as well.
