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 can exist in the “noisy” high temperature environment of the eye of a bird.

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…
You will find other descriptions here of Henri Weimerskirch’s work on Albatrosses under Albatrosses on this site as well as Anna Gagliardo’s work on the use of smell in navigation. A book recently written by Adam Nicholson called “The Seabirds Cry” is fascinating about the mythology and lives of the sea birds in his book;…
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…

Many swallows make a 6,000 mile journey from Europe to winter in South Africa and back. I believe, that the way that swallows make this migration is by…
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. Click here for the full article: The Quantum Robin
I love this little observation by James Mather… “I was on a ladder clearing the gutters end of last week, and over a period of hours heard a number of flocks of birds gathering to migrate, and I could see them heading off in V-formation. Then, at one point, low cloud closed in, but I…
