In itself, the pendulum does not attract Tree Swallows or Eastern Bluebirds. Once the swallows and bluebirds have adopted the nesting box, the pendulum makes quite sensation! It's guaranteed to keep pesky English Sparrows out of the nest and allow the desired birds to nest successfully.

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.
