Yes. There is evidence that some animals, probably most notably sea turtles, have the ability to sense the Earth's magnetic field (although probably not consciously) and to use this sense along with their several other senses for purposes of navigation. However, the issue of magnetic orientation by animals is really more a matter of biophysics rather than geophysics and we will therefore refer the curious reader to the following authoritative articles:
