Ingia / Ingia

The behavioural signals used in mate selection are a key component in the evolution of premating isolating barriers and, subsequently, the formation of new species. The importance of mating signals has a long tradition of study in songbirds, where many species differ in their song characteristics.

Ingia / Ingia

Song in oscine birds is a learned behavior that plays important roles in breeding. Pronounced seasonal differences in song behavior and in the morphology and physiology of the neural circuit underlying song production are well documented in many songbird species. Androgenic and estrogenic hormones

Ingia / Ingia

Bird song is a complex behavior that requires the coordination of several motor systems. Sound is produced in the syrinx and then modified by the upper vocal tract. Movements of the hyoid skeleton have been shown in the northern cardinal (Cardinalis cardinalis) to be extensively involved in forming

Interruptibility of long call production in tamarins: implications for vocal control.

Ingia / Ingia

Vocal production can be highly deterministic, such that once the central nervous system generates a signal to call, the vocalization is emitted immune to external events. Conversely, vocal production can be modulated by auditory feedback such that interference or disruption can cause an individual

Ingia / Ingia

Passerida is a monophyletic group of oscine passerines that includes almost 3500 species (about 36%) of all bird species in the world. The current understanding of higher-level relationships within Passerida is based on DNA-DNA hybridizations [C.G. Sibley, J.E. Ahlquist, Phylogeny and Classification
