Hironbec Pendulums were invented by Rene Lepage of Quebec to protect Tree Swallows and their nests from destruction by House Sparrows. This video, created by the Salmon Creek Tree Swallow Project, and edited and narrated by Chris Gates, shows how Pendulums work, and when and how they should be introduced to Tree Swallows.
Persons wishing to order Pendulums should visit www.hironbec.com, the website of Mr. Lepage.
There is additional information on Pendulum operation available for download at the Sparrow Damage page of the website www.treeswallowprojects.com
