Migratory birds navigate with the help of the Earth’s magnetic field, but how do their compasses work? Peter Hore of Oxford University discusses whether quantum coherence and entanglement could be the answer.

The bar tailed Godwit is about 37/39cms (15ins) long which summers in the arctic yet migrates to warmer locations during the winter. These include astonishing non-stop flights over the Pacific to New Zealand every Northern winter. As you can see from the tracks, you will see it flies in a perfect straight flight from the Arctic…
Recent work at Bognor University by a team headed by Charles Bishop has shown they actually follow the contours as they fly from their breeding ground in the high lakes North of the Himalayas south over the Himalayas into the Indian sub continent See wikipedia for images and an overview http://en.wikipedia.org/wiki/Bar-headed_goose This is an interesting…
We know that cuckoos nest over winter in the Congo and breed in Europe. UK cuckoos arrive in the latter part of April and lay their eggs in another bird’s nest. The common host of cuckoos are Reed warblers, Meadow pipits and even non-migratory Robins. The juveniles a month later in May. The fledgling casts out the other…

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…
Elephant seals (sea elephants) are large, oceangoing seals in the genus Mirounga. There are two species: the northern elephant seal (M. angustirostris) and the southern elephant seal (M. leonina). Both were hunted to the brink of extinction by the end of the 19th century, but numbers have since recovered. The northern elephant seal, somewhat smaller than its southern relative, ranges over the Pacific coast of the U.S., Canada and Mexico….

This article was published in Navigation News and is published with permission from the editor and the author. This is a very important piece of work by one of our heroes as it begins to show how magnetic information can be processed by an animals. Cryptochromes look alike a very promising route to understand how animals navigate as well as the quantum aspects covered.
