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…
A conceptual framework on the role of magnetic cues in songbird migration ecology
This paper is difficult to understand but it summarises the work on animal navigation to date. The key is that all the research which is confident that animals navigate using magnetic cues are not necessarily the whole story and that all navigators use all the clues they can get to help them. Recently there was…
Monarch Butterflies
Here is a link to Monarch Butterflies http://phys.org/tags/monarch+butterflies/ Editor’s remark I have difficulty understanding these results which suggest that Cryptrochromes are involved which I am fairly clear is impossible as there is not enough time for the quantum coherence to take place. Inclination compasses are very inaccurate as there can be huge changes locally due to…
Animal navigation is based on Quantum effects theory
We believe that animal navigation is based on Quantum effects which are inimical to a classic Newtonian science based approach. This world is so weird and unlikely that it is impossible to understand properly or as Feynman said if you think you understand it you must have misunderstood. Dowsers know that you can access this…
How young cuckoos find their winter grounds
Please find this interesting link to important work on Cuckoos done by Kasper Thorup and his team in Denmark. http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0168940 They were able to tag and therefore track fledgling cuckoos. This work is very important as the major question for us is, how does a fledgling cuckoo find its way to its wintering grounds in…
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…
