A conceptual framework on the role of magnetic cues in songbird migration ecology

This paper is difficult to understand but it summarises the work on animal navigation to date.  The key is that all the research which is confident that animals navigate using magnetic cues are not necessarily the whole story and that all navigators use all the clues they can get to help them.  Recently there was a paper in   Navigation News (the magazine of the Royal institute of Navigation),  Professor Mike Salmon, the research professor in the Biology department of Florida Atlantic University says he thinks that Logger head sea turtles navigate using instinct!
