Prothonotary warblers nested in a decorative gourd hanging on my porch a few years ago when I lived in Chester county. They used the grassy nesting material left by wrens. My sister had them nesting just off her porch in Oktibbeha county Mississippi in a birdhouse that very same year! It seems they may be making it a habit. Wonder if anyone has information on houses that might specifically encourage prothonotary warblers? They may not require specific design since my gourd was actually designed to be a feeder and had broad openings on two sides though the wren nest had blocked the entire space.

Cyndi and I co-authored the article's text, but the story comes from Cyndi's many hours of observations and is beautifully illustrated with her intimate photos of the nesting family. The article is described in more detail in my recent blog post: http://vickiehenderson.blogspot.com/2014/03/tennessee-conservationist-nest-box.html If you are not already a subscriber to the TN Conservationist Magazine, consider visiting the subscription page at their website: http://www.tn.gov/environment/conservationist/conservationist_subscribe.shtml The magazine is self-supported by subscriptions, the price of which has remained at a low $15.00 a year for many years. Each issue contains informative conservation articles about Tennessee's heritage and wildlife, with frequent articles about birds. Many of the photographers and authors are people you will recognize from both TOS and other conservation organizations. This is a well-circulated way to keep Tennessee informed about the birds we enjoy and their future.
