This morning, my wife and I took a walk on Whitney Beach, which stretches along the northwest edge of Longboat Key. Renowned for its wide, flat surface, plentiful shells and large congregations of sea birds, the beach is also a nesting site for least terns, black skimmers and snowy plovers. In order to protect the nesting areas, ropes and signs are used to keep beachcombers away from these colonies, minimizing human disturbance.
Today, the beach was relatively quiet toward its northern end, populated by small flocks of royal and Sandwich terns, ubiquitous laughing gulls, a couple snowy egrets and a few shorebirds (willets, sanderlings and ruddy turnstones); the initial highlight was a large flock of magnificent frigatebirds that soared above the coast. Farther south, however, were this year's nesting sites; there, a large number of black skimmers and least terns occupied the beach, the latter already attending to chicks that waddled across the sand.
Clearly in protective mode, adult least terns took aim at my floppy sun hat, swooping in to encourage my departure. They may be the smallest terns in North America but they certainly can be aggressive; after all, successful nesting on open beaches and sandy river islands (favored by least terns) necessitates bold and attentive parents. I kept my distance and the tern attack soon abated.
