Travelling from my hotel to TechEd I've been walking through Vondelpark - a place festooned with more high speed hazards(otherwise known as Bicycles!) than I've ever seen before! In the trees there were many Green Parrots which were sqwarking everywhere I went.
I spoke to some local people who informed me that over the years many people have let their domestic Parrots go in the park - they have bred - leading to a large population in the wild.
What the heck has this got to do with security
There is a large community of Parrots in London too, on the Thames near Walton up to and including Staines made famous by Ali G!
