The acorn woodpecker (melanerpes formicivorus) is a highly social species with co-breeding behavior. The vocalization of the acorn woodpecker is thought to be complex due to the complexity of its social system. This research aims to study the vocalization and relevant social behaviors of the acorn woodpecker through various aspects such as the vocal features, the functions of different call types, general patterns of vocal communication, intraspecific /interspecific responses to vocal signals. In the study the distributed wireless sensor network will be applied to collect and monitor the vocal signals of acorn woodpeckers. Furthermore, this system could identify and localize individuals from their calls. After the sensor network is built, the information collected by the network will be used in bioacoustic and behavioral analysis.
