Abstract
Behavioural experiments on disparity-based depth perception in two barn owls (Tyto alba) implicate that these frontal-eyed predatory birds can acquire depth information through stereopsis. Neurophysiological data revealed that disparity sensitivity in telencephalic neurons is due to position-shifts, phase-shifts, or a hybrid of the two. Computational modeling demonstrated that depth extraction is possible from the outputs of such cells.
