This link is important as it gives you more information on the work done by David Keays et al, which proved that the magnetite particle array supposed to exist in the upper beak, creates a magnetic compass response mechanism for birds, does not exist.
As this article suggests the other candidate for magnetic response is a quantum effect in the cryptochromes in the birds eyes.

Intro This piece has been forwarded to me by one of our editors: Simon Raggett. He gives us the quantum twist. You will also find much written here on the subject of avian navigation based around gravity from our editor Antonio Nafarrate, who has been in communication with the authors of this piece.

Questions by Richard Nissen. Replies by David Higgins – President of the Royal Pigeon Racing Association. If pigeons are not trained do pigeons roam far from their lofts? Probably no more than a mile. Do you think that homing into the loft when it is near by is done using geographical features such as roads…

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…
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…
Please note that the BTO (British Trust for Ornithology) carry out a brilliant Cuckoo tracking project. We think that we need to be sure that we are clear how fledglings make the journey to their wintering grounds. As they have never been there before, how do they know how to get there? If any of…
Cuckoo Migration is one of the great mysteries and to date there is still no agreement on how Cuckoos find their way to the Congo for the winter starting from different locations in Europe. The team at Copenhagen University under Prof Kasper Thorup have been able to tag fledgling cuckoos to follow their migration….
