Woodpeckers (Picidae) at Pasoh: Foraging Ecology, Flocking and the Impacts of Logging on Abundance and Diversity

摘要: Woodpeckers are extremely diverse in the lowland rain forests of Southeast Asia. In these forests, up to 16 species can be found, representing highest syntopic diversity for woodpeckers world. Understanding how foraging resources partitioned this species-rich guild is both ecological and management concern. We investigated ecology 13 woodpecker at Pasoh Forest Reserve (Pasoh FR) from May-July 1998. obtained interpretable sample sizes four (Meiglyptes tristis, M. tukki, Picus mentalis Reinwardtipicus validus). These exhibited distinct behaviors by using different substrates or attack maneuvers, heights. Although overall abundance was similar between logged unlogged forest, there were significant differences relative individual species. The most likely reason lack heterogeneity mature forest compared forest. relatively low snags, treefalls, treefall gaps probably limit number that use resources. While conducting study, we also documented flocking interactions among several species, Greater Racket-tailed Drongo (Dicrurus paradiseus). complex associations warrants further study.
