Over-shadowed by eye-catching vocal and visual signals, chemical communication has long been overlooked in birds. This study aimed at exploring whether volatile composition of the uropygial gland secretion (UGS) of birds was associated with the ...

The domestication of the larynx: The neural crest connection. [PDF]
We outline the developmental link between the larynx and the neural crest. This connection provides a powerful test of the predictions of the most prominent hypothesis in domestication research, the neural crest domestication syndrome hypothesis. Abstract Wolves howl and dogs bark, both are able to produce variants of either vocalization, but we see a ...

Comparative analysis of protocadherin-11 X-linked expression among postnatal rodents, non-human primates, and songbirds suggests its possible involvement in brain evolution. [PDF]
BACKGROUND: Protocadherin-11 is a cell adhesion molecule of the cadherin superfamily. Since, only in humans, its paralog is found on the Y chromosome, it is expected that protocadherin-11X/Y plays some role in human brain evolution or sex differences ...

Auditory processing in the zebra finch midbrain: single unit responses and effect of rearing experience [PDF]
In birds the auditory system plays a key role in providing the sensory input used to discriminate between conspecific and heterospecific vocal signals. In those species that are known to learn their vocalizations, for example, songbirds, it is generally ...

Parental influence on begging call structure in zebra finches (Taeniopygia guttata): evidence of early vocal plasticity [PDF]
Begging calls are signals of need used by young birds to elicit care from adults. Different theoretical frameworks have been proposed to understand this parent–offspring communication. But relationships between parental response and begging intensity, or

Thalamostriatal and cerebellothalamic pathways in a songbird, the Bengalese finch [PDF]
Abstract The thalamostriatal system is a major network in the mammalian brain, originating principally from the intralaminar nuclei of thalamus. Its functions remain unclear, but a subset of these projections provides a pathway through which the cerebellum communicates with the basal ganglia.

Complex sequencing rules of birdsong can be explained by simple hidden Markov processes. [PDF]
Complex sequencing rules observed in birdsongs provide an opportunity to investigate the neural mechanism for generating complex sequential behaviors. To relate the findings from studying birdsongs to other sequential behaviors such as human speech and ...

Dynamic expression of cadherins regulates vocal development in a songbird. [PDF]
BACKGROUND: Since, similarly to humans, songbirds learn their vocalization through imitation during their juvenile stage, they have often been used as model animals to study the mechanisms of human verbal learning.

Biological clocks as age estimation markers in animals: a systematic review and meta‐analysis
ABSTRACT Various biological attributes associated with individual fitness in animals change predictably over the lifespan of an organism. Therefore, the study of animal ecology and the work of conservationists frequently relies upon the ability to assign animals to functionally relevant age classes to model population fitness.

The carotenoid redshift: Physical basis and implications for visual signaling
Carotenoid pigments appear redder as the concentration of a pigment increases. The carotenoid redshift arises due to the asymmetrical reflectance spectra of carotenoid‐colored ornaments and the exponential attenuation of light. Structures that increase the path length of light through carotenoid pigment also cause a redshift, as we demonstrate in the ...
