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…
New Study Fuels Debate About Source of Birds’ Magnetic Sense
This link gives you a very good overview of the latest arguments about whether Cryptochromes, which are sensitive to magnetic fields and exist in the eyes of birds, help with their navigation. All the great and good involved in this field are quoted. I personally do not think that the quantum effects in a Cryptochrome…
Avian Compass Reloaded
http://www.2physics.com/2012/10/avian-compass-reloaded.html Please find this interesting piece entitled The Avian Compass Reloaded by Dagomir Kaszlikowski at the Centre for Quantum Technologies, Department of Physics, National University of Singapore. Kaszlikowski talks about the the quantum effect that is required to enable the Cryptochromes in the eye of the European Robin to be sensitive to the earth’s magnetic field….
Bird Migration
I believe that it is possible that dowsers may have unique insights into how birds navigate over long distances. There seem to be three principle discussions on how navigation is done: firstly using magnetic orientation especially in homing pigeons, secondly on the use of olfactory clues, thirdly on the anomaly that Robins (Passerines) have their…
Hippocampus by Simon Raggett
I was at a lecture on animal navigation at the Royal Society this week. Nothing world changing, but possibly some useful bits of background regarding navigation. This deals with the mammal brain, but given the similarities in behaviour between mammals and birds one can assume the birds might achieve some similar process. The important brain…
Bird Navigation
I was delighted to be able to attend the animal navigation conference at Reading University in May 2008. I attended as a dowser with the theory that animals can and do follow dowsable clues including earth energy lines as an aid to navigation. We all know that dowsers (water diviners) can find water. However what…
