Mystery of Bird Navigation System Still Unsolved
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…
Light pollution is important
Atchoi, E., Mitkus, M., Vitta, P., Machado, B., Rocha, M., Juliano, M., Bried, J. & Rodríguez, A. 2023 Ontogenetic exposure to light influences seabird vulnerability to light pollution. Journal of Experimental Biology 226. doi: 10.1242/jeb.245126. Atchoi 2023 (no pdf) Light pollution critically affects the fledglings of burrow-nesting seabirds, leading to massive mortality events. The successful management of this pollutant depends…
Some thoughts on The Migration of the Arctic Terns by George Nissen
See www.arctictern.info see the google tour You can see the tern’s tracks from their breeding grounds in Greenland in the Arctic (in yellow) to their wintering grounds in Antarctica. The white track is the averaged return flight. The terns dawdle down to their Antarctic wintering grounds looking for food etc. The Earth’s Prevailing winds. Note:…
Avian Navigation
www.bbc.co.uk/news/science-environment-17855194 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…

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…
