The Swinging Society?

A purely opportunistic attempt. Problem: through the window, standing back so as not to disturb and stop the game. Sometimes it was only one on the swing, sometimes three. Others stood on the ground below, either waiting their turn or in admiration and awe as the Pampas Grass frond went up and down in a huge arc.

I was having trouble with focus, and just did not think of using the 'Servo' focus mode! Still, it was fun for a few moments.

And then they were gone — all except one who lay in shreds on the lawn, sad remains of a young Sparrowhawk's evening meal! Couldn't get to the camera soon enough to catch the S-H at his carnage-making gourmandising.
