Info from Licensor: "This video was show in my back yard in Dunstable, Massachusetts, in early spring, when all the birds start to reappear in our area. My father had taken a liking to birds, and noted that our large area of land had plenty of opportunity to make it a great hobby. He built boxes and hotels for the traveling birds, and was lucky enough to keep getting the same pairs and babies from the previous year. He read up on them, and realized when they liked to build their nest, especially out of white feathers. We have chickens, so there are plenty of small white feathers everywhere. The tree swallows will watch for you, and take every white feather you give them."
