Comparative hearing : birds and reptiles

TL;DR: The morphology of the inner ear is examined to predict the hearing range and sensitivities of species within the Order Galliformes and provides significant insight into how species differences in BP morphology evolve and putative relationships with size, vocalizations and life history.

TL;DR: The thesis describes the design and evolution of echolocation in the South and Southeast Asian Swiftlets and treats potential morphological adaptations in the echlocation system, i.e. in the syrinx, ear, and brain.

TL;DR: The spatiotemporal events leading to morphogenesis of the columella and middle ear structures are documented and the first gene expression data for this region is provided, which identify candidate genes and facilitate future functional studies and elucidation of the molecular mechanisms of columlla formation.

TL;DR: In this article, the authors reviewed the contributing ornithologists' current research in birds' acoustic communication with an ecological and evolutionary focus, and also identified the areas they feel will dominate future research efforts.

TL;DR: The process by which spatial cues are used for localizing a sound source in a free-field listening situation is summarized, and current evidence does not support the view that auditory motion perception is anything more than detection of changes in static location over time.

TL;DR: In this article, the smallest angular separation that can be detected between the sources of two successive tone pulses (the minimum audible angle) was determined for each of three subjects, and the threshold angles were analyzed in terms of the corresponding threshold changes in the phase, time, and intensity of the tone at the ears of the subject.
