Magnetoreception – the ability to sense the Earth’s magnetic field
David Keays is one of the mega stars of animal navigation research and has spent a life time trying to work out how magnetism might work. Here is a summary of his latest work: Magnetoreception is the ability to sense the Earth’s magnetic field, which is used for orientation and navigation. Behavioural experiments have shown…
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…
Eyes are essential for magnetoreception in a mammal
Here is another interesting paper: Mole-rat lives underground and basically cannot see and is often studied to understand how they navigate. Caspar, K. R., Moldenhauer, K., Moritz, R. E., Němec, P., Malkemper, E. P. & Begall, S. 2020 Eyes are essential for magnetoreception in a mammal. Journal of The Royal Society Interface17, 20200513. doi: doi:10.1098/rsif.2020.0513.

The Common Toad: Bufo, bufo.bufo
Observations from the “Observer’s book of British wild animals” first published in 1938. It was compiled by W.J.Stoke. “I found this piece fascinating as it describes the navigational skills of Toads. There are also other works that suggests that Newts operate in a similar way, making long journeys out of the water but not getting…

Animal Navigation Model
Antonio Nafarrate, one of our associate editors has sent his latest thinking: I am very interested in how so much of what he presents here fits with other pieces in our puzzle to understand how Animal Navigation might work Richard Nissen editor I have some new ideas that may connect my Animal Navigation Model with…
