So when you get a topic asking you to brainstorm ideas involving an outdoor play area for children that also acts as a birdhouse, the first question you may want to address concerns bird feces.
For some reason I really like the idea of either hanging birdhouses or interactive ones. The first and third idea incorporate hanging houses that are more free flowing and tend to move with the wind or motions of nature while the second idea incorporates an observation tube where the kids can sit and watch the birds. I wanted all the of the ideas to foster a sort of love for natural observation in the kids. I wanted them to be able to play and watch the birds at the same time.
Although to be honest, they will probably be traumatized when they inevitably get pooped on.
