Another description of how animal navigation might work
In a recent address to RIN Dr Kate Jeffery of the Institute of Behavioural Neuroscience at University College London described a very complete structure for understanding animal navigation. See https://animalnav.org/navigation-networks-in-the-brain/ We at www.animalnav.org have been struggling with exactly these concerns. Prof Jeffery postulates that you need four things to create a navigation system A compass…

A champion racing pigeon can be released 400 miles from its home loft, in a place it has never been before, and return within 1 day. The last 40 miles of its journey, the bird navigates by sight. But over the other 360…

The Compass Within – Sense of direction
Article in Nature volume 18 number 4 April 2015 This is a very important piece of work which begins to bring us to an understanding how a sense of direction works and which is NOT magnetic based. We at animalnav.org know that this “sense of direction” must be crucial for navigation so Simon Raggett’s (one…
