Abstract

The initial vocalizations of breeding catbirds in response to predator models positioned at their nests were analyzed to determine if they were correlated with the type of later defense employed (attack model vs. no attack), intensity of defense, and type of predator model (snake vs. blue jay). Statistical differences were found in the types and numbers of vocalizations used in relation to type of nest predator and form of future defense. The data suggest that the initial catbird vocalizations may indeed encode a variety of information.
