The Avifauna of Mt. Kitanglad, Bukidnon Province, Mindanao, Philippines
Intensive inventory work on the Mt. Kitanglad massif of north-central Mindanao, Bukidnon Province, Republic of the Philippines, revealed a diverse avifauna. In all, 198 bird species were detected, of which about 172 were likely breeding in the area, placing the mountain among the most diverse sites that have been surveyed in the country. Three migratory species (Luscinia calliope, Turdus chryso...
متن کاملEffects of Long-term Forest Management on a Regional Avifauna
We compared breeding bird populations on and off of the Savannah River Site (SRS), South Carolina, to determine whether management practices on SRS have affected abundance and composition of the resident avifauna. We assessed relative abundance by comparing Breeding Bird Survey (BBS) data from six routes off SRS with three surrogate routes generated using point-count data from four research pro...
متن کاملMapping Global Diversity Patterns for Migratory Birds
Nearly one in five bird species has separate breeding and overwintering distributions, and the regular migrations of these species cause a substantial seasonal redistribution of avian diversity across the world. However, despite its ecological importance, bird migration has been largely ignored in studies of global avian biodiversity, with few studies having addressed it from a macroecological ...
متن کاملMacroecological signals of species interactions in the Danish avifauna.
The role of intraspecific and interspecific interactions in structuring biotic communities at fine spatial scales is well documented, but the signature of species interactions at coarser spatial scales is unclear. We present evidence that species interactions may be a significant factor in mediating the regional assembly of the Danish avifauna. Because >95% of breeding species (n = 197) are mig...
