BTO Cuckoo Tracking
Please note that the BTO (British Trust for Ornithology) carry out a brilliant Cuckoo tracking project. We think that we need to be sure that we are clear how fledglings make the journey to their wintering grounds. As they have never been there before, how do they know how to get there? If any of…
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…
The energy and mechanisms needed for cryptochrome navigation
At the RIN 13 animal navigation conference there was a lot about bird navigation and particularly, the Continental Robin, Erithacus rubecula which it is proposed, navigates through the action of the cryptochromes in their eyes which are disrupted by radical pairs caused by the effect of a magnetic field. This means that in theory they…
Swallows
Useful links wikipedia.org/wiki/Swallow birdsofbritain.co.uk/bird-guide/swallow.asp Below is the of the swallow migration map: www.bbc.co.uk/blogs/autumnwatch/2009/11/lates… We, in Europe, measure the beginning of Spring by the arrival of the swallows. 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…
Navigation Networks in the Brain
Professor Kate Jeffery of University College London gave the annual address to the Royal Institute of Navigation (RIN) this year (2014). This article published in RIN’s Navigation News is, for me, a seminal step forward in describing the parameters of animal navigation and building a structure to delve deeper into how navigation might work. Her idea that…
Do you have a sense of direction?
There is a lot of work going on in the navigation field. All the researchers in this field are now clear that navigation takes place in the sub-conscious. I made the mistake of thinking that native peoples who seemed to navigate perfectly without any aids could tell me how they did it, but language is…
