A new Mesembriornithinae (Aves, Phorusrhacidae) provides new insights into the phylogeny and sensory capabilities of terror birds
(Society of Vertebrate Paleontology, 2015-03)
Terror birds constitute the most outstanding group of the South American Cenozoic avifauna. Considered as apex predators, their hunting skills have recently been examined, but their diversity is still unresolved. Here we ...
Molecular phylogenetics of Doraditos (Aves, Pseudocolopteryx ): Evolution of cryptic species, vocal and mechanical sounds
(Wiley Blackwell Publishing, Inc, 2020-12-01)
While bird vocalizations (produced by the syrinx) have been the focus of countless studies, mechanical sounds (produced by external body structures) have received much less attention. In particular, the evolutionary interplay ...

Estudo anatômico e imaginológico dos órgãos celomáticos do Ramphastos toco - Müller, 1776
(Universidade Estadual Paulista (Unesp), 2019-02-22)
A obtenção de diagnóstico clínico em aves é um desafio, porque geralmente os sinais clínicos são inespecíficos e o exame físico é muito limitado por fatores fisiológicos e anatômicos em comparação aos mamíferos domésticos. ...
Automatic reconstruction of physiological gestures used in a model of birdsong production
(American Physiological Society, 2015-09)
Highly coordinated learned behaviors are key to understanding neural processes integrating the body and the environment. Birdsong production is a widely studied example of such behavior in which numerous thoracic muscles ...
