The FD tried to get to a cockatoo that was lost and perching on the roof of a hospital - needless to say, the bird would spook off every time they tried to get near but, at night, somebody in the hospital saw him still perching there and had the common sense of opening a window - the bird just flew in! There is nothing but offering a place with light in the night for a bird to come to it (I use this trick when I can't get one of the little ones to go back into the cage: make the room dark and place a light shining into the cage)
