Always disturbing when I'm processing photos on my computer and discover one like this. Don't notice when I'm taking the shots so always a bit of a shock. This is a barn swallow that seconds before was stretching out its wing. Apparently it decided to do a little preening on its back which resulted in the headless bird shot. Personally I think the bird quietly laughed to itself saying: just wait till she sees that one.
