In this BBC article, we're told that they are intending to spend approx £250 per nest to move the pigeons (they're vermin, by the way) to Ayr.
Apparently they ruled out anti-roosting spikes as being "unattractive" - well, no more unattractive than the Parliament and its inhabitants then, eh?
As per usual, the lunatics at "Advocates for Animals" are claiming this is a good use of public money, suggesting that we, the Scottish taxpayers would be happy that the pigeons are going to a wildlife sanctuary... Heaven forbid that disease spreading flying menaces be killed - it's not as if there aren't enough pigeons in the world.
... now if only we could get rid of those pesky MSPs too...
