In December 1909, businessman and philanthropist Anthony R. Kuser proposed to the zoo that Beebe be allowed to go on a voyage around the world to document the world's pheasants, which would be financed by Kuser. Hornaday strongly objected to this proposal, describing Kuser as an "evil genius" who was attempting to steal Beebe away from his duties at the zoo. However, the zoo ultimately decided in Kuser's favor, partly because the scientific papers produced by Beebe's trip to Guiana had been beneficial to the zoo's reputation. Hornaday appointed Crandall as the zoo's acting curator of birds, giving him the duty of caring for its birds in Beebe's absence. Beebe and Blair left for their expedition accompanied by Robert Bruce Horsfall, whose job would be to provide illustrations of the birds for the book that would hopefully result from this expedition.
