Miriam Liedvogel works on the genetics of migration
Miriam Liedvogel is working on the genetics of migration and recently gave a presentation on this at RIN13: the world animal navigation conference. She asks the big key question: How do animals migrate? She suggests that we should think about – What direction do they need to go Timing: when to go Distance: how far…

Avian Navigation System
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…
Annual Conference of Dowsers on Animal Navigation
In September 2015 I was asked to give a workshop at the Annual Conference of Dowsers on Animal Navigation. Of course I talked about how animals, including birds, navigate and all the outstanding questions that remain on how they do it. Those who came to my presentation were some of the best dowsers in the…
Olfactory landmarks and path integration converge to form a cognitive spatial map
This paper on olfactory landmarks is interesting as it covers the idea that the distinctive smell of a place can help navigation by creating a new landmark for helping an animal navigate. The recognition of a spatial landmark by its sensory features poses a problem for neural circuits. Fischler-Ruiz, et al. show how this problem…
Albatross Navigation
The Albatross that ranges over huge areas of the South Atlantic Region in overcast weather where sun clues are seldom available to return to their breeding islands such as Crozet in the South Atlantic, work done by Bonadonna et al in 2004 shows that manipulating the albatrosses by altering their magnetic environment made no difference…
