I loved the sound of the purple martin colony, the birds gurgling and chirping as they flew in great circles overhead, the conversations and arguments that took place as the birds arrived back at their nests with insects for the babies. I knew I would miss the martins when they left for their winter homes in South America. And I knew they would be leaving soon. The end of July was approaching, and the week before Yearly Meeting, I had seen them gathering all together as a flock and making huge sweeping flights through the air. So the morning of Yearly Meeting, I set a tape recorder and microphone at the base of the colony, and left it there while I puttered around. When I had put everything in the car, including my map and my cup of coffee, I went across the yard to pick up my tape recorder, throw it in the back, and trundle off to Yearly Meeting. That was when I discovered the little martin, lying on its back about two feet from the tape recorder . . . [Truth in advertising: the thumbnail picture is of barn swallows, not purple martins.]
