.... I went to the local nature reserve again this evening and spotted a couple of Buzzard's scouting the area from on high.
Luckily the EF500mm & EF1.4x converter were attached to the EOS 1DIII, so I managed to get this shot, even though they were quite a way above my head.
Not a lot else around, but it's very windy, and a bit colder than expected, so maybe everything (apart from the rabbits!) are in hiding.
