Abstract
Habitat fragmentation has been considered as threat to biodiversity and maintaining large forest patches is often considered the key in preserving biodiversity in fragmented landscape. However, the effects of habitat fragmentation are not universal to all bird species. We mapped the locations of all observed bird individuals in a 50 hectares farm by territory mappings during the breeding seasons from 2005 to 2007. We classified habitat types by aerial photograph and measured vegetation structure of each patch. Almost 90% of the registration spots were located in forest patches. Forward variable selection of logistic regression suggested the distributions of different statuses of species in forest patches were affected by different habitat characters. Family richness of sub-canopy plants was the most important factor to dominant residents; and canopy foliage volume was to non-dominant residents. Wintering species mainly affected by habitat types. We conclude that, habitat type is a strong effect to habitat selection of birds, even in a very small patch. The habitat with highly diverse characters is a key factor to attract different statuses of forest birds.
