In 1919, Osborn helped secure Beebe a new research station in Guiana to replace Kalacoon: Beebe was offered Kartabo Point, an outpost of a New York-based mining corporation. Beebe was enthusiastic about the new station, and it proved very successful for conducting the same detailed analyses of wildlife within small areas that had been performed at Kalacoon. At Kartabo Beebe discovered the phenomenon known as an ant mill, a column of ants following itself in an endless loop until nearly all of them died of exhaustion.
