How to operate the pendulum with bluebirds

This system is amazingly efficient. The first version of this pendulum was tested in 1991 and proved to be a failure.

The sparrows managed to pass it in less time required to say it. Several protypes followed and in 1993 the first nest box with pendulum was a complete success!

Success repeated itself hundreds of times across Quebec as fast as the pendulum underwent important changes. Today, because of this pendulum, the swallows and the bluebirds are truly protected from the english sparrows.
