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…
This paper is a very good overview of the thinking about avian migratory navigation and acknowledges that birds use all the cues that are available to them to navigate successfully. Magnetic Compass Orientation in a Palaearctic–Indian Night Migrant, the Red-Headed Bunting Summary The earth’s magnetic field, celestial cues, and retention of geographical cues en route…
Dolphins and bats don’t have much in common, but they share a superpower: Both hunt their prey by emitting high-pitched sounds and listening for the echoes. Now, a study shows that this ability arose independently in each group of mammals from the same genetic mutations. For more reading follow this link: ow.ly/xkfk30nysHa
In January 2021 I had the opportunity to have another test of my theory that migratory animals (fledgling cuckoos) use an innate sense of direction to find their way to their destination. I did a zoom presentation to some of the best dowsers in Britain and asked them to track the routes followed by fledgling…
Please note that Tom Guildford is a very important Animal Navigation professor working at Oxford University. Manx Shearwaters have been extensively studied as they have amazing navigational skills but do not seems to rely on magnetism. Richard NissenEditor This is a summary of a paper protected by copyright: Syposz, M., Padget, O., Wynn, J., Gillies, N.,…
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…
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.
