ABSTRACT:
A birdhouse includes a one-way viewing wall or window which allows the birds to be viewed inside the birdhouse without allowing them to see their observer. The birdhouse can be mounted on a window sill such that the one-way viewing wall is adjacent to a window pane, thereby allowing any number of observers to simultaneously view the birds in their natural environment without intruding on their privacy. Thus, the birdhouse functions as an observatory.
