This study shows that the visual system of white zebra finches differs morphologically from that of normally coloured (wild type) birds, although eye pigmentation and retinofugal projection are normal. In white zebra finches, the recrossing tectorotundal projection is enhanced and a new (reciprocal) connection is established between the n. rotundi of both hemispheres. The morphological alterations found in this study may contribute to the previously described enhanced processing of ipsilateral stimuli in white zebra finches. © Lippincott-Raven Publishers.
