This is an English term for sheep that learn to live in a particular location who do not stray from their “land”. For us this is another piece of the jigsaw of how animals operate in the wild and know where “home” is.
DEFRA ( Britain’s government Agency for Rural Affairs) asked ADAS to do this report for them.

Showcased at the Royal Institute of Navigation is this interesting piece on animal migration. Maura O’Connor is a freelance journalist based in Brooklyn. Her first book is: “Resurrection Science: Conservation, De-Extinction and the Precarious Future of Wild Things,” from St. Martin’s Press. She is currently at work on a second book – an exploration of navigation traditions, neuroscience, and…
Susanne Åkesson is one of the foremost academics working in the field of animal navigation. Her recent paper: “Timing avian long-distance migration: from internal clock mechanisms to global flights” is impressive and important. Please see attached the whole paper: Timing avian long-distance migration: from internal clock mechanisms to global flights. One of the critical questions is…
Intro This piece has been forwarded to me by one of our editors: Simon Raggett. He gives us the quantum twist. You will also find much written here on the subject of avian navigation based around gravity from our editor Antonio Nafarrate, who has been in communication with the authors of this piece. Please follow…
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…
The avian navigation system is rather complex, based on many factors, and it even used two aspects of the magnetic field. If, in a given situation, one can show that the receptors in the beak have no effect, that does not mean that they do not have one in another situation! Anaesthesia of the upper…
Warrant11 2016 Here is a fascinating paper about The Australian Bogong Moth Agrotis infusa: which is the most amazing Long-Distance Nocturnal Navigator. As they navigate at night their feat is perhaps even more amazing than the migration of the Monarch butterfly in the USA. Richard Nissen editor Warrant E, Frost B, Green K, Mouritsen H, Dreyer D, Adden A, Brauburger K and Heinze S (2016) The Australian…
