摘要

During April-July 1997, we censused birds in three woodlands near Arnprior, Ontario, Canada using conventional point counts (n = 12)and point counts supplemented With "pishing" (n = 12), a well-known method for attracting various bird species. Overall, 3.6 (19/100) more species were detected per census using pishing. Irrespective of statistical significance of individual species, 45 (74/100) of the 61 species were detected on ore days using pishing, whereas 5 (8/100) species were detected on more days using the conventional method.
