Tags work on the basis of emitting a signal to receiving transmitters but if you have been in the Highlands you will know with your phone how many "black spots" there are. How often the signal transmits is open to the user, the more it transmits the more expensive data recovery.

The tag also works on solar power which can be varied in Scotland thereby running down the battery. So there are all these factors to consider. So say we set the transmitter to emit every hour and it stops at 10 am. We get a precise fix on the signal, or do we?

No we don't because we need to triangulate off at least two other masts, to get it accurate. If the signal is due to transmit again at 11 am, that means we potentially have another hours flying time. So what does this mean. Well there is a reason the data is not shared.

I am sure you can work out why. I can take the data and look for Moorland and say that's where the last signal was. I can't be challenged and if I agitate the media enough I have a story and if I am politically motivated even better. As explained above I will never find the bird.

We can look at Crime Scene Examinations, Locard's theory on trace at the scene of a crime and modern technology, which could be used to catch anyone involved in raptor crime. CP is how not to do it. I should also mention from the against side there are huge financial gains made
