Jeane I put phase one of your suggestion into operation yesterday and suspended a lovely glittery CD right over their favourite spot.
"Ahhh" sez I rubbing me hands with a confident glee.."that'll shift em bejayzez!!"
However my euphoria was short lived as at half time in one of the football matches I went out to survey my victory, my success, only to find 2 pigeons happily dozing right beside the bloody CD !!
Strewth!! sez I while having a cataclysmic seizure!
