Research on the function of acoustic signals has focused on high-amplitude, long-range song (LRS) and largely ignored low-amplitude songs produced by many species during close-proximity, conspecific i
Calling interactions in group-housed zebra finches: correlation values from vocal interaction matrices for call-type and bird combinations, calculated from PSTHs. Matrices were transposed to columns (
Birdsong often serves as a territorial signal, and vocal performance (the degree of vocalising close to vocal production or respiratory limits) can play a role in expressing a sender’s aggressiveness.
Bird vocalizations are critical cues in social interactions as they convey temporary information varying with the social context, e.g. the signaler motivation when facing a rival or a potential mate.
