Vocal Tract Articulation in Zebra Finches
Birdsong and human vocal communication are both complex behaviours which show striking similarities mainly thought to be present in the area of development and learning. Recent studies, however, suggest that there are also parallels in vocal production mechanisms.

THE WAVELENGTH SENSITIVITY FUNCTION FOR THE ZEBRA FINCH [PDF]
With lights of different spectral compositions filtered from a white, the flicker response contours for the zebra finch are found to exhibit the same general kind of relationship between flicker excitation and wavelength as is found in the case of man ("cone" contours), with the same filters.

Resurgent Na+ currents promote ultrafast spiking in projection neurons that drive fine motor control
The zebra finch robust nucleus of the arcopallium (RA) directs singing by providing descending projections to brainstem motor neurons. The authors show that electrophysiological characteristics of RA neurons rely on resurgent Na+ currents that emerge ...

Maternal effects underlie ageing costs of growth in the zebra finch (Taeniopygia guttata). [PDF]
Maternal effects provide a mechanism to adapt offspring phenotype and optimize the mother's fitness to current environmental conditions. Transferring steroids to the yolk is one way mothers can translate environmental information into potential adaptive ...

Slc44a2 Deficiency Unveils an IFN‐I–Dependent Feedback Control of pDC Egress
Working model of SLC44A2‐mediated maintenance of pDC homeostasis. This model illustrates two central mechanisms by which SLC44A2 regulates pDC homeostasis: (1) SLC44A2 limits IFN‐I production by exporting amino acids (T, N, Q), thereby preventing spontaneous pDC activation.

Gene duplication and fragmentation in the zebra finch major histocompatibility complex
Background Due to its high polymorphism and importance for disease resistance, the major histocompatibility complex (MHC) has been an important focus of many vertebrate genome projects. Avian MHC organization is of particular interest because the chicken

Cardiac morphological and morphometric analysis of Ardea alba
Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

Classifying avian drinking behaviour: ecological insights and implications in a changing world
ABSTRACT Water is a fundamental currency of life, and its availability significantly influences animal behaviour, physiology and distributions. However, our knowledge around the dependence on water for drinking and the direct and indirect mechanisms driving related behaviours remains partial in the context of changing climates. Here, we review patterns

Housing quality affects male mouse attractiveness to females ABSTRACT Females generally prefer mates with traits indicating low stress (e.g., large size; good health). In captivity, stress from suboptimal housing might therefore reduce male attractiveness.

This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.
