Apparently the organ they do it with is located in (or behind?) the right eye, again the same as birds. They can actually "see" the mouse's magnetic field against the normal field of the earth.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4912713243046142041.post-77778519676400922792011-02-26T13:04:54.020-06:002011-02-26T13:04:54.020-06:00Some Czech researchers recently published their fi...Some Czech researchers recently published their finding that foxes appear to be able to judge the distance and depth of their pounces by calibrating against an innate perception of the earth’s magnetic field.
