Birdsong's lovely most of the time, and nice to wake up to. This, however, was not a bird. This was a four inch tall demented Luciano Pavarotti on helium with with short term memory difficulties, repeating two lines from Refrains In C# Too Irritating To Be Used As Ringtones by the lesser known Dutch composer Hans Twit.
It knew what it was doing, too. Oh yes. After ten minutes waiting to see if it'd give up, I went up to the window - and it stopped, for about thirty seconds. Back to bed - it started again. I opened the window, and it flew away. Peace... I went back to bed.
Parrottini had flown all of five metres away and continued singing with redoubled chirrupiness, this time with full dawn chorus backing. He went away just after I decided to admit I was awake and get up.
Off to put the kettle on.
