Week after week, I watched this pair of yellowlegs as they foraged back and forth across a shallow, grassy mudflat that developed after weeks of unusually heavy rains. I never saw them fly, and I never heard them call; they were too busy plucking indeterminate creatures from the sandy mud.
While they fed, I amused myself by trying to decide if they were greater yellowlegs (Tringa melanoleuca) or lesser yellowlegs (Tringa flavipes). There are ways for an experienced birder to distinguish between them — body size, the length of the bill, the nature of their call — but I never was certain which species I was seeing until the day something startled them. Calling to one another, they flew up and away from their buffet table. A later comparison of yellowlegs calls convinced me they were Lesser, not Greater — but no matter which species, I found them a great delight.
