Used to be loads of them around here, they do seem to have got less in the last few years, but i suppose the population numbers must fluctuate. Five or six of them outside your bedroom window make a heck of a racket, and you want to hear them mating..............
But then I suppose given the way they are dressed, its understandable the noises they make doing it.
Someone must be keeping tabs on them, coz the 4 I get on my patch on a regular basis have got different colour paint sprayed on their backs.
