Abstract

The community structure of the birds of Calauit island was determined via the species richness, species diversity, and density in six different habitat types: molave forest, secondary old growth, boho stand, quasi-savanna, mangrove, and beach forest. Birds were classified according to feeding guild and trophic groups in each habitat. The partitioning scheme of bird species found in the forests was known by correlating the positions with the vertical structure of the vegetation. Species richness was significantly higher in the quasi-savanna than in any of the remaining habitat. Birds species diversity was highest in the molave forest though followed closely by quasi-savanna and the secondary old growth forest. Extensive overlaps in home ranges were significant, exhibited even by restricted species. The bird species were classified in six trophic groups, all of which were present in the forest habitat. No significant differences were found between the molave and secondary old growth forest regarding the number of species in varying stratification.
