In songbirds, song complexity and song sharing are features of prime importance for
territorial defence and mate attraction. These aspects of song may be strongly influenced by …

The evolution of complex signals has often been explored by testing multiple functional
hypotheses regarding how independent signal components provide selective benefits to …

The principal strategy used to deal with animals recovered from trafficking operations is to
release them back into nature. Our goal was to test the feasibility of using vocalizations to …

Vocal complexity is an important concept for investigating the role and evolution of animal
