Here is another image of a Carrion Crow but this time showing it in its landscape. This was taken with an 800mm focal length and the bird itself was 58.5m away from my position.
Most people think that if you have an 800mm lens then you can photograph birds from miles away. Even though this crow was fairly close, the 800mm still renders it small in the frame but shows the landscape off nicely.
Carrion Crow, Corvus corone, Malvern Hills, Worcestershire, November, 2011.
