Watch out - buzzard about

Came home at midday today to get some serious work done on the computer. Managed to get most of it done and am finishing the rest now.

A pair of buzzards nest in the area and frequently fly over but are usually careful to avoid flying over humans (especially those with a long lens). Something had rattled them today and they were mewing overhead for most of the afternoon. (Maybe she was proposing to him?!)

My office has a skylight which is more or less at eye level and this was taken through the open window.
