YAsoooooooBU.They are not fighting,they are mating so produce lots more of the nasty little cackling maniacs which attacked my neighbours elderly cat. There needs to be loads more so that when they swoop in front of my car-and they wait for me I'm sure-and I say "helloMrMagpieand how'syourwifetoday" under my breath;then I can find a second one easily. Or another 4 or 5.(Rather have silver or gold than a secret)!
I would never harm them but I'm finding it hard to think of a more annoying noise! (apart from slurping, people chewing their nails, Tim Westwood's voice and my neighbour doing "oosh oosh" noises whilst pretending to box in the middle of the street! )
