McDonald" Subject: Raptor Visual Capability MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Hi All-------- Seems to me, I have heard stories from a couple different sources that some raptors can perceive light in the ultraviolet range and, thereby, are able to locate rodent prey by watching for activity along urine-marked rodent trails (which were said to be visible under ultraviolet). Does anyone know: are these true stories? or are they nice birdie-fairy tales? If so: does anyone know of the literature references to substantiate these stories? Thanks for any information supporting or negating these stories.
