Cuckoo Migration, a theory 2021
In January 2021 I had the opportunity to have another test of my theory that migratory animals (fledgling cuckoos) use an innate sense of direction to find their way to their destination. I did a zoom presentation to some of the best dowsers in Britain and asked them to track the routes followed by fledgling…

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…
Another description of how animal navigation might work
In a recent address to RIN Dr Kate Jeffery of the Institute of Behavioural Neuroscience at University College London described a very complete structure for understanding animal navigation. See https://animalnav.org/navigation-networks-in-the-brain/ We at www.animalnav.org have been struggling with exactly these concerns. Prof Jeffery postulates that you need four things to create a navigation system A compass…

Mathematical analysis of the homing flights of pigeons based on GPS tracks
Ingo Schiffner At the RIN 11 Animal Navigation Conference Ingo Schiffner, presented a paper: Mathematical Analysis of Pigeon Tracks, characterisation of the underlying Navigational Process and now he has produced another paper covering Mathematical analysis of the homing fights of pigeons based on GPS tracks. For me, this work begins to create an underlying mathematical basis…
