Open Barn/Shed/Garage Windows & Doors

Open barn/shed/garage windows and doors from early April through mid-September: Barn Swallows rely on human-made structures for nesting. With the decline of agriculture, barns are falling down or being repurposed with windows shut tight. Barn Swallows tend to like darker cave-like interiors, and they often place nests on beams/rafters near the ceiling. Barn Swallows nest in loose colonies and singly, so both large barns and smaller structures are important. For more information on the close relationship between humans and Barn Swallows throughout their evolutionary history, see this article.
