Male frogs produce sounds to attract conspecific females as well as advertise their own territories to other males. Subsequently male frogs acoustically interact with each other, which induces various types of synchronized behavior. In this seminar, I will introduce the synchronized calling behavior of actual male frogs as well as theoretical studies using a phase oscillator model [1, 2]. Next, I will introduce our recent projects on the identification of the phase oscillator model from empirical data [3] and the extension of the model to a hybrid dynamical system in which male frogs intermittently switch their behavioral mode based on internal condition and also the interaction with other males [4].
