Thanks Daniel, they do get quite tame but I like seeing them flying free and living their lives, pooping on cars! I know they are considered a nuisance where they nest and make a mess, but I like their characters, they way they've escaped from being kept and exploit man's habitats. In some cities here there are now peregrin falcons nesting on tall buildings and living off the feral pigeon flocks, which is great news when the natural habitats of the falcons are under threat from egg collectors and disturbance.
