Abstract: The Philippine archipelago is one of the top conservation a??hotspotsa?? due to the high number of endemics under extreme threat from habitat destruction. Progress towards conserving biodiversity has been achieved in recent decades. However, many challenges remain, including lack of information on the effects of extensive and rapid habitat loss on the countrya??s fauna. Fieldwork was conducted in the Subic Bay Watershed Reserve to investigate effects of different land uses on forest birds and butterflies. Community assemblages, species richness and populations, as well as levels of predation on nests and larvae were compared across a disturbance gradient. Higher levels of disturbance resulted in changes to communities and predation. An analysis of correlates of extinction risk in all Philippine resident birds revealed that traits associated with specialized ecological needs are important predictors, reflecting the impact of habitat destruction as a threat. Further research into species biology and ecology are urgently needed.
