Abstract: I present new information about 34 of the 195 resident land and freshwater bird species of Northern Melanesia, an area characterized by a rich avifauna, high endemism, and great geographic variation in morphology. There are many examples of geographic variation in voice, behavior, habitat preference, altitudinal range, vertical stratum, abundance, and nest. Possible vocal convergence or mimicry between sympatric populations of different species is described between the goshawk Accipiter albogularis and the kingfisher Halcyon chioris, between the cuckoo-shrike Coracina [tenuirostris] and other species in its mixed-species foraging ...
