1. Evidence of tutoring in the development of subsong in newly-fledged Meyer's Parrots Poicephalus meyeri
Os ''subsongs'' são ensaios vocais emitidos pelas aves jovens para exercitar suas vozes. Nos pássaros canoros, ''subsongs'' são exibidos por indivíduos em seu primeiro ano de vida. Estudos com Poephila guttata sugerem que os jovens aprendem seus cantos de um tutor vocal, seu pai. Neste trabalho examinamos os ''subsongs'' em seis papagaios Poicephalus mey

2. Song selectivity and sensorimotor signals in vocal learning and production
Bird song, like human speech, is a learned vocal behavior that requires auditory feedback. Both as juveniles, while they learn to sing, and as adults, songbirds use auditory feedback to compare their own vocalizations with an internal model of a target song. Here we describe experiments that explore a role for the songbird anterior forebrain pathway (AF

3. Novel motor gestures for phonation during inspiration enhance the acoustic complexity of birdsong.
Sound generation based on a pulmonary mechanism typically occurs during the expiratory phase of respiration. Phonation during inspiration has been postulated for the calls of some amphibians and for exceptional sounds in some human languages. No direct evidence exists for phonation during inspiration in birds, but such a mechanism has been proposed to explai

4. Individual variation in neuron number predicts differences in the propensity for avian vocal imitation
Avian song learning involves memorizing and reproducing song material produced by conspecifics. In several species song repertoire size correlates with the overall volume of two song-related brain regions, the HVc (acronym used as the proper name) and the robust nucleus of the archistriatum (RA). We raised male zebra finches with two adult tutors and found t
