Watching the show "quite interesting" if anyone know it... In short they talk about randomly fascinating stuff...
Anyway, to the hunting side of it...
They were talking about foxes and apparently foxes always try to pounce on their prey from a north-easterly direction. Seems they can detect the magnetic field of the earth or some such and use this to tell which way is which.
There they got this from is that they found any time a fox pounces on prey from the north-east, they had a 73% success rate.
When they were forced to pounce from any other direction, they only had an 18% success rate. So they try to pounce from the north-east.
Just interesting anyway, but maybe any fox hunters here can set up behind their targets from now on and have the foxes all be looking the opposite directiong
