In spanish there is ventanear and its derived terms, meaning to look out the window, in a busybody/nosey way. (It could also mean to peep into windows, in some places, but that's not important). It is literally derived from ventana (window).
Is there an English equivalent word or phrase? It brings to mind Gladys Kravitz from the show Bewitched. I know busybody is partly close, but it doesn't require peeking or watching from afar.
