Editor’s remark

I have difficulty understanding these results which  suggest that Cryptrochromes are involved which I am fairly clear is impossible as there is not enough time for the quantum coherence to take place.

Inclination compasses are very inaccurate as there can be huge changes locally due to magnetic anomalies in the ground.

I still have the problem that knowing where North is, is of no help, if you do not know the bearing of where you are going.  Ie You must  know where your destination is.

I look forward to any feedback on all of this.

I have heard that The Monarchs that set off on these migrations are not the same individuals as end at their destinations – another conundrum!
