The view of the leaping squirrel mid-air as he bounded across the garden milliseconds after I took today's shot, from which you can see he did in fact have a head.
Sadly I deleted the one of him sliding down the bird table, his head was missing from that one too but it would have been an easy entry for the 'upside down' theme this week! I'll leave you to imagine it but please don't trouble to think of any intelligent comments to add below...! :)
