摘要
The birdhouse comprises a fledgling board (12) or platform which is deployed just below the entrance hole (16) in order to provide an exercise area for the young birds so that they may test their legs and wings just prior to taking their first flight. The platform 12 can be pivoted about hinge 15 so that it lies flat against the front of the birdhouse (Fig 1). The platform can also be deployed in a roughly horizontal position when it is retained by retainer 17.
