The major part of this report is an account of birds collected by the
expedition of the Bernice P. Bishop Museum of Honolulu, Hawaii, to North
Borneo, from June 24, 1962, through January 14, 1963. Most of the time
spent in the then British Colony was devoted to collecting in lowland
habitats. The chief collecting localities were in the vicinity of Quoin
Hill on the Semporna Peninsula, and near Kalabakan. Approximately two
weeks were spent in surveying the Tenom area. Additional work was done
by the North Borneo Department of Agriculture after my departure, mainly
by Antonio D. Garcia.
