hi it can fly no eggs , in 3 weeks that we have seen it came down once as soon as we got there it flew to the fence and then on the tree , it sleeps on the tree branch and also the roof  , the tree branch goes over the part of the roof,

if it was a flat roof ok i would go up there but not on a tiled roof ,

do you think i should stop putting its bowl on the roof and keep the bowl on the ground, but she sometimes knocks the plastic bowl off the roof ,but does not bother that i know off come down. my wife has called it patricia.mmmm

even had the baker across the road come over with a knife and fork.
