Spatio-Temporal Distribution of Kalaw (Buceros Hydrocorax L.) at the Foothills of Mt. Pangasugan, Baybay City, Leyte, Philippines

Mt. Pangasugan contains one of the few remaining intact lowland dipterocarp forests in Leyte which is home to many threatened avain species including the Kalaw. The study aimed to understand the spatial distribution and temporal activities of kalaw to provide information to support conservation progrom. The preferred habitat of kalaw was characterized by the dominance of species belonging to family Dipterocarpaceae and gap species of Araliaceae and Moraceae. Kalaw occurred in stands where there were large trees with natural cavities which could be used for nesting and fig trees and other fruit bearing gap species as source of food. Specific perches were big tall trees which comprise the canopy and emergent layers. The result of the study suggest strengthening protection of the remaingin secondary forest as habitat of kalaw and put a stop to current activities that may have affected the biological clock of Kalaw
