Magnetoreception and the ruling hypothesis
This paper is fascinating. This site has always been sceptical about Magnetoreception – the magnetic navigation story for the same reasons that are discussed here. No-one has found the magnetic receptors. the cryptochrome story requires conditions in the eye that are not conducive to quantum effects and knowing where North is does not help without…

Path integration
Adelaide Sibeaux 1 , Cait Newport1, Jonathan P. Green1, Cecilia Karlsson 2, Jacob Engelmann 3 & Theresa Burt de Perera1 have recently published a paper showing that fishes as well as other animals use path integration to find their way home. I believe this is very important and probably the main way we navigate. Path integration maybe the way…

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…

Atlantic herring use a time-compensated sun compass for orientation
Lisa Spiecker1,*,‡, Malien Laurien1,*, Wiebke Dammann1, Andrea Franke2,3, Catriona Clemmesen4 and Gabriele Gerlach1,2 ABSTRACT Atlantic herring (Clupea harengus), an ecologically and economically important species in the northern hemisphere, shows pronounced seasonal migratory behaviour. To follow distinctive migration patterns over hundreds of kilometers between feeding, overwintering and spawning grounds, they are probably guided by orientation mechanisms. We…

The efficiency of varying methods and degrees of time compensation for the solar azimuth
This paper on navigation using the sun is an interesting one by Richard Massy and Karl R. Wotton. Already Tristan Gooley the natural navigator and one of our heroes walked across Crete to prove that the brain can in fact compensate for the movement of the sun during the day and keep a course by…
