Saw this Sparrowhawk on our lawn eating a mouse(we checked after it had gone) photo taken at maximum zoom, hand held through glass. I also managed videos but since hand held and zoomed they are not too good . A blackbird came onto lawn, saw the Sparrowhawk , gave a squawk and rapidly flew away.
Modified title of photo from Kestrel to Sparrowhawk following ID by 'Kestrel (Derek)'
