This great grey shrike has been at Prestwick Carr all winter but never comes close (at least when I am there). This photo was taken from just over 200m away with a 600mm lens and a crop sensor, giving an effective focal length of 960mm. I didn't have a tripod so I managed by propping the monopod against a fence post. The first photo is uncropped, the second is a big crop of the same image.
So, just a record shot but I guess it is not bad considering - at least you can make out what it is.
