Behavioral responses to frequency specific head related transfer functions as filtered by the facial ruff in the Barn owl (Tyto alba)
The barn owl is, due to its numerous morphological and neuronal adaptations to sound localization, a long-established model animal for the auditory system. Besides extensive research on the topic within the last decades, it is still unclear how direction- and frequency-dependent physical cues …

Anatomical, morphometrical and biomechanical studies of barn owls' and pigeons' wings
Wings and feathers of barn owls (Tyto alba) were investigated with anatomical, morphometrical and biomechanical methods in order to specify noise reduction and noise suppressing structures evolved by the owl. Pigeons (Columba livia) with a similar body weight were taken as a reference species. Barn …

Charakterisierung von Acyl-CoA-Reduktasen
cDNA sequences encoding fatty acyl-CoA reductases were cloned from the uropygial glands of barn owl (Tyto alba), domestic chicken (Gallus gallus domesticus) and domestic goose (Anser anser domesticus). Heterologous expression studies in Saccharomyces cerevisiae showed that they encode membrane …

Processing of auditory signals in the forebrain of the Barn Owl : neural mechanisms of across-frequency integration
Interaural time differences (ITDs) of acoustic signals represent a major cue for sound localization in most animals including humans. Due to the finite propagation velocity of sound and the different path lengths to the two ears, ITDs change with the azimuth of a sound source. Binaural comparison …
