Please look at this link as it covers important ground on Avian Navigation. You will see that one of our heroes David Keays has established that the magnetite structure in the beaks of pigeons does not exist. The magnetic theory still has problems because you cannot navigate using a compass without knowing where you are, where you are heading and a map.

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…
Evidence for a critical role of olfactory cues for homing after displacement in open ocean. Procellariiformes are pelagic birds which wander in the open sea most of the year and often nest in remote oceanic islands. These birds are able to pinpoint their breeding sites following straight routes even if their nesting island is located…
Here are the points to be added that I anticipated or predicted that they should happen as proof or implied consequences of my animal navigation model. The posting in the website is Introduction to my Ideas from Sept 2013 – “Gravity and Gyro effects are the basis of animal navigation, by Antonio Nafarrate“. Appendix. 1) From a paper by…
At RIN11 Ingo Schiffner gave his presentation Mathematical Analysis of Pigeon Tracks (the characterisation of the underlying navigational process). He analysed 167 tracks with birds navigating from four different locations and from two different directions. His theory is that pigeons navigate using at least four different components and these components change over the course of…
A summary: The RIN Conference spends a lot of time on pigeon navigation, with delegates coming from all over the world. The leading players in this world are the Wilschkos from the Johann Wilfgang University Germany, M. Walker from the University of Auckland, and A. Gagliardo of the University of Pisa. Overall, it was decided…

Many swallows make a 6,000 mile journey from Europe to winter in South Africa and back. I believe, that the way that swallows make this migration is by…
