Purple Martin House: Griggsville, Illinois
Positioned in boggy terrain betwixt the Missouri and Illinois rivers, Griggsville long put up with a serious mosquito infestation until the local Jaycees became wise to the fact that purple martins are the bird world's most prolific skeeter-eaters.
To fend off the bugs, in 1962 they commissioned a manufacturer to make dream homes for the birds. These homes were positioned along Quincy Street, which is now known as Purple Martin Boulevard.
