There was s terrible cacophony of bird noise outside, so I looked into my unspectacular urban garden and saw a spectacular sight on my lawn. Magpies were mobbing a small bird of prey that had caught something.
I think it may have been a sparrowhawk, and the captured bird was very similar coloured, so perhaps a starling. When I opened the garden door the magpies fled, and the sparrowhawk (?) zipped into a snug, sheltered corner of the garden. I thought it might stay there for a moment, and took my eyes off it for an instant to grab my clogs, but when I turned back it had gone.
The magpies continued yammering for several minutes longer.
What an excitement!
