In February 1909, Beebe and Blair traveled to British Guiana, in the hope that with Roosevelt's support, it might be possible to establish a permanent field research station there. Another goal of this expedition was to find and capture a hoatzin, a bird whose clawed wings caused it to be considered an important link in the evolution of birds from reptiles. Beebe made extensive documentation of hoatzin behavior through field glasses, but their plans to capture one were foiled when they had to return home early due to Blair breaking her wrist. Despite their failure to obtain their most sought-after prize, the expedition still returned with 280 live birds of 51 species, 33 of which were new to the zoo, although several of these died or escaped during the long trip back to New York. Beebe summarized this expedition in his book "Our Search for a Wilderness", which was enthusiastically well-reviewed.
