Sight Test

I'm thinking it's time for another visit to the optician to renew my prescription and perhaps choose some new goggles. Those wild creatures that rely on specialised vision to survive do not have that luxury.



The kestrel may need to hover and glide for much of the day before finding what he's looking for. This one, over Blacka Hill, would have needed to pick out movement of small mammals in the difficult leggy heather territory below .



Even humans well fitted out with prescription lenses may not be aware of the presence of our largest wild animal only a few yards away.



Unless, of course, the nearby male, somewhat less shy, decides to investigate.
