I originally jotted down this poem when I first heard it quoted in a documentary DVD called Winged Migration. This was a documentary about birds and their migration patterns, much more interesting than it may sound—they took a small ultra-lite plane up and flew around with flocks of birds to get some fantastic close-up photography. A web search for the author turns up nothing, so apparently he has no books or collections of poety available. The DVD Winged Migration should be widely available; try Amazon.
