Birds have evolved many different strategies to cope with varying predation. Birds throughout the world are known to respond to threats, in part related to their size, social preferences, and foraging habits. Since there is relatively little known about these mechanisms for tropical birds of Cloud Forests, I have performed the following study in the Monteverde area of Costa Rica. A total of 129 calls of two types were played to 33 species in the Monteverde area during the course of this study. Anti-predator responses were recorded for birds exposed to a call playback of the Barred Forest-Falcon (Micrastur ruficolli) and the scold call of a White-breasted Wood-Wren (Henicorhina leucosticta). The degree of response was compared to a bird’s si...
