We think about modern development destroying natural habitats and generally thsi is true, but some birds have adapted readily to man-made structures.
Recently Sue, my wife, was attracted to the sound of young birds whilst crossing London Bridge and on closer inspection witnessed starlings going in and out of the decorative structures of the front of Adelaide House.
I suppose to a starling it is just like a hole in a tree!
