I’ll never forget the first time I heard the call of a Sandhill Crane. It was early June, and I was halfway through an eight-day backpacking trip in the Sapphire Mountains. Sitting in a meadow one evening and refilling my bottle at the oxbow of a quiet creek, I began to hear a sound unlike anything I’d ever heard. It was part elephant, part jackhammer, and part squeaky door hinge. One thing seemed clear: no way had that sound been made by a modern animal, and certainly not by a bird.
