NOTES ON OCCURRENCE AND FEEDING OF BIRDS AT CRATER MOUNTAIN BIOLOGICAL-RESEARCH STATION, PAPUA-NEW-GUINEA

During 1989-93, 170 species of birds were observed and 1787 individual s captured in mist nets at the Crater Mountain Biological Research Sta tion, Chimbu Province, Papua New Guinea Populations of many species fl uctuated on animal or supra-annual schedules; 46 species were consider ed transients. Areas of the forest where many understorey trees had be en removed exhibited reduced mist net capture rates. Comparisons among four other sites in southern Papua New Guinea reveal striking similar ities among site in number of species and trophic organisation. Range extensions, weights and natural history observations are reported for many species. Feeding observations of nectarivorous and frugivorous bi rds at over 50 species of plant are reported.
