Bird Communities of the Lower Waria Valley, Morobe Province, Papua New Guinea: A Comparison between Habitat Types:

From June, 2007, to February, 2009, the Waria Valley Community Conservation and Sustainable Livelihoods Project (WVCP) completed an inventory survey of the birds of the lower Waria Valley, Morobe Province, Papua New Guinea. Four land use types – agricultural, secondary forest edge, primary forest edge and primary forest – were surveyed using Mackinnon list surveys. In total, 125 species representing 43 families were identified, of which 54 (43.2%) are endemic to the islands of New Guinea and the Bismark Archipelago. The avifauna of primary forest edge and primary forest was more species rich and diverse than that of agricultural habitats. Agricultural habitats also differed significantly in both overall community composition and some aspects of guild composition compared to all three forested habitats. Nectarivores and insectivore-frugivores formed a significantly larger proportion of species in agricultural habitats, whereas obligate frugivores formed a significantly greater proportion in forested habita...
