The Bird with the Sky on it's Back by Brian and Marci Swanson
Saturday, July 18; 10:30 am at Central Library
8601 Mathis Avenue, Manassas, VA 20110
People have loved Bluebirds since they saw them on their farms in earlier centuries. Loss of habitat almost doomed them until far sighted folks began to put up nest boxes for them. The result has been a great comeback for the beautiful Bluebird.
Marci and Brian Swanson have been putting up nest boxes for 20 years and have been active in several Bluebird societies, including the one here in Virginia. Their program will talk about how to attract Bluebirds to your garden, what to feed them if you wish, and the biggest threat they face.
