Repertoire Size and Syllable Sharing in the Song of the Clay-Colored Thrush (Turdus grayi)
(2012)
Song repertoire size and extent of song sharing provide information about social interactions that occur in songbird species. We recorded the songs of eight male Clay-colored Thrushes (Turdus grayi) in San José, Costa Rica ...
Song structure and syllable and song repertoires of the Saffron Finch (Sicalis flaveola pelzelni) breeding in Argentinean pampas
(A B Academic Publisher, 2018-06)
Empirical descriptions of vocal behaviour in avian communication are important in understanding its meaning and role in shaping the social and genetic relationships among individuals in a population. In this study, we ...
Song plasticity over time and vocal learning in clay-colored thrushes
(2015)
Songbirds have been traditionally classified into close-ended or open-ended learning species according to the length of the sensitive period during which birds are able to memorize new vocalizations. Closed-ended learners ...
Repertoires of Spike Avalanches Are Modulated by Behavior and Novelty
(Universidade Federal do Rio Grande do NorteBrasilUFRN, 2016)
Neuronal avalanches measured as consecutive bouts of thresholded field potentials
represent a statistical signature that the brain operates near a critical point. In
theory, criticality optimizes stimulus sensitivity, ...
House Wrens Troglodytes aedon reduce repertoire size and change song element frequencies in response to anthropogenic noise
(2020-06-09)
Anthropogenic noise (≤ 3 kHz) can affect key features of birds’ acoustic communication via two different processes: (1) song-learning, because songbirds need to hear themselves and other birds to crystallize their song, ...

The structure and organization of song in Southern House Wrens (Troglodytes aedon chilensis)
(Springer, 2015-08)
Studies of birdsong across very broad geographic scales, such as between the north temperate zone and the tropics, provide special opportunities to understand the role of variable ecologies, life-histories and mating ...
