Nature has created mechanisms to detect salient objects like food, prey or mates. Visual search is the process of shifting gaze from one salient object to another. It has both a stimulus driven bottom-up component as well as a task-driven top-down component. This is well studied in human and primates but not so much in other animals. It is, therefore, a challenge to increase our understanding of visual search in non-primate animals. The barn owl is a predator having frontally oriented eyes, but lacking eye movements. Because of such specializations, this bird offers itself for the study of visual search. We study mechanisms of visual search in this animal on both the behavioural and neurophysiological levels. In this talk I will present our main findings on these matters.
