It's very difficult to take a half-decent photo of a swallow. Believe me, I've tried. They're fast little blighters. But, this morning, I finally succeeded, by hiding behind the sheets on my washing line and firing away as a swallow fed its young on my back fence:
"Oh bloody hell, he's there with that camera thing. Right, let's go and sort him out."
It does look rather determined, in a menacing sort of way.
