Differences In Bird Communities On The Forest Edge And In The Forest Interior: Are There Forest-Interior Specialists In Japan?, Reiko Kurosawa, Robert A. Askins

Biology Faculty Publications

Most North American bird species that are less successful in small forests than in large forests, are forest-interior specialists that winter in the tropics. These species have declined in small forests because of high rates of nest predation and brood parasitism near the forest edge. To determine whether migratory forest-interior specialists are also important components of bird communities in Japan, we surveyed bird populations on plots at the edge and in the interior of deciduous forests in Hokkaido and Kyoto. Surveys were conducted during the breeding season in forest fragments using the point count method. We calculated edge indices for …
