Mystery of bird navigation system still unsolved
http://www.newscientist.com/article/dn21688-mystery-of-bird-navigation-system-still-unsolved.html We have always said that the work of our hero David Kaeys is critically important in demolishing the magnetite cluster in the beak theory. This theory proposed that the magnetite group acted as a compass which enabled birds to sense the magnetic field and therefore use this for navigation. I am delighted that other…
Ways pigeons might home
Here is a fascinating YouTube video discussing different ways a pigeon might home. The people shown here are our heroes, who are really important people in the animal navigation world and especially in Pigeon navigation. You will find Tim Guildford at Oxford University, who believes that pigeons follow landmarks, The Wiltchokos who believe in magnetic…
A conceptual framework on the role of magnetic cues in songbird migration ecology
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…
Avian navigation
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…
Some thoughts on The Migration of the Arctic Terns by George Nissen
See www.arctictern.info see the google tour You can see the tern’s tracks from their breeding grounds in Greenland in the Arctic (in yellow) to their wintering grounds in Antarctica. The white track is the averaged return flight. The terns dawdle down to their Antarctic wintering grounds looking for food etc. The Earth’s Prevailing winds. Note:…
Modelling collective navigation via non-local communication
A recent paper called “Modelling collective navigation via non-local communication”has been published by S. T. Johnston(1) and K. J. Painter(2). They tell us that a group of individuals produce better navigational results thanindividuals which is why flocks of birds are more efficient than a solo migrant. TheRAF confirms this where they have found that a…
