The barn owl is a nocturnal hunter, capable of capturing prey using au- ditory information alone . The neural basis for this localization be- havior is the existence of auditory neurons with spatial receptive ﬁelds . We provide a mathematical description of the operations performed on auditory input signals by the barn owl that facilitate the creation of a representation of auditory space. To develop our model, we ﬁrst formu- late the sound localization problem solved by the barn owl as a statistical estimation problem. The implementation of the solution is constrained by the known neurobiology.
