Sammanfattning

During two trips to West New Guinea in 1954 and 1960, the author made an extensive collection of birds as well as field notes in a variety of habitats ranging from the western islands adjacent to the coast of West New Guinea, the northern coastal areas from Sarmi to Hollandia (Kotabaru), and the mountains of the interior including a newly-opened valley, the Ilaga, in the Nassau Range. Some three hundred eighty-two forms of birds were observed during a fourmonth period. Descriptions of the habitats are given. In addition discussion is made of altitudinal shifts of range and the phenomenon of crowding and overlap of related species at feeding trees. At such feeding trees under compacted situations, high intensity calls and demonstrations of aggressive behavior occur. Extensions of range are listed and data on breeding seasons are presented indicating overwhelmingly that similar species breed at two rather different seasons geographically, earlier in the calendar year in the central areas of West New Guinea, later in the calendar year in the western islands and west coast, presumably correlated with the weather and monsoonal seasons. In the species list a considerable number of field notes are included as well as native names and occasional native beliefs.
