only assume there was no shortage of food here and I couldn’t figure out why this osprey hadn’t yet made an attempt at catching some. By now, twenty minutes had passed. Even my own patience was waning, when all of a sudden something changed. Something had caught the osprey’s eye. Everything shifted, the pace quickened. The osprey began to dive with lightning speed. With a splash, it made contact with the water. I waited for the water to settle, for the bird to reveal its success or lack thereof. And when it took off, I could see what it had been waiting for all this time… a very large flounder. This is strictly speculation, but it certainly appeared that this osprey was holding out for the seafood dinner he/she really wanted. It seems safe to say that this particular osprey had a preference for flounder. Where the Dunlin Forages One afternoon I sat patiently on the side of a tidal pool on Kiawah’s beach and observed several shorebirds foraging in the wet sand and shallow water. The longer I observed these birds, the more predictable their behaviors became. The plovers were foraging about five feet from the surf, while the sandpipers were probing close to and just beyond the water line. In the deeper water, the taller birds were foraging. The subject in this photo is a Dunlin. Dunlin are medium-sized shorebirds —slightly larger than the nearby sandpipers—equipped with long, slender, down-curved bills. These birds were spending their time foraging in water that was one to two inches deep. As my subject probed in and out of the water, it dawned on me that the sand it was probing was just a smidge too deep, just out of reach, for the nearby sandpipers and way out of reach for the plovers. Sandpipers, and especially plovers, boast short beaks, unable to match the depth the dunlins can reach.  So, this depth was just right for the dunlin. My dunlin was foraging in an area that was exclusive to its kind. As a result, it didn’t need to compete with the other species of shorebirds that were likely all foraging for very similar foods within its vicinity. This experience helped me to realize that the sheer diversity of birds on Kiawah’s beach is reliant upon their ability to coexist. It was amazing to see how these subtle changes in bill length and bird height can create an inclusive feeding environment for our shorebirds.    WINTER/SPRING 2019 • VOLUME 41 Skimmers and Sunsets Gulls, terns, and skimmers are all members of the same family, but have several different ways of obtaining food. Terns are precision hunters. Flying above the water and diving down head first to snag a fish they’ve targeted with their bill. Gulls tend to be more opportunistic feeders. Sometimes they will grab their own prey, but they also seem to enjoy stealing fish from other birds. Even Cheetos from an unsuspecting person will satisfy a gull. Skimmers, however, are very specialized in their prey- capture technique. They fly low to the edge of a shallow body of water, adjusting their wing beats to seemingly glide just inches off the surface. They then dip their elongated bottom mandible into the water, thereby skimming the surface, as their name suggests. Their bills are incredibly sensitive and as soon as they feel a potential food item against their beak, they swiftly snap it closed, trapping their prey. As the sun begins to set on Kiawah’s beach, you’ll find less activity from the terns and the gulls. Since these birds are visual hunters, sunset means meal time has ended. But skimmers, well, skimmers are tactile feeders. All they need to see is the shoreline and the rest is simply felt. As I sat on the beach that dusk, paying little attention to the sun setting behind me, I felt enthralled by the black skimmers flying up and down the shoreline. As they hunted for dinner, the colors of the sunset reflected in the water all around them. It was a truly magical Kiawah scene. In the end, through all of the nature realizations, I’ve also come to realize something else: Photography encourages one to be patient and slow down. There is so much to learn and see in this world but failing to sit and observe may prevent one from appreciating and really understanding. For me, the osprey fostered appreciation that individual animals may have preferences, the dunlin taught the importance of small differences in beak length, and the skimmers revealed that some birds work later than others in the never-ending hunt for that meal in a perfect setting.
