Rollo Beck's Collections of Birds in Northeast New Guinea

ABSTRACT In 1928–1929 Rollo Beck discovered in New Guinea a spectacular new species of bowerbird, Sericulus bakeri, which according to his specimen labels he collected near the previously well-studied lowland town and former colonial capital of Madang. That seemed so implausible that suspicions arose that Beck had intentionally falsified the locality—especially when it eventually turned out that the new bowerbird is instead confined to the nearby Adelbert Mountains. Beck made this discovery in the course of amassing large collections in northeast New Guinea that, in fact, have never been published as a whole, although Ernst Mayr (1941) in his List of New Guinea Birds included some of Beck's records. Much doubt has remained about Beck’s collecting localities. Hence we have now reconstructed Beck’s itinerary on the basis of his field diary and specimen register; the letter by his wife who accompanied him; a spreadsheet of his cataloged specimens in the American Museum of Natural History (AMNH); and correspo...
