Max C. Thompson, Birds from North Borneo
“ Authorities of the United States National Museum and The American Museum of Natural History generously permitted me to work at those institutions, using their specimens for comparative studies. Other specimens were borrowed from the Museum of Comparative Zoology, Rijksmuseum Van Natuurlijke Historie, British Museum (Natural History) , and the Yale Peabody Museum. Dr. Alexander Wetmore, Herbert Deignan, and Charles Vaurie helped with some of the more difficult taxonomic problems. ”
