Florida Birds: Shore Birds
Florida American Oystercatcher birdAmerican Oystercatcher - Since it is one of the largest and heaviest of our shorebirds, the oystercatcher is unmistakable. It is striking in appearance: dark-brown, black, and white, with a bright red bill. When in flight, a diagonal white stripe in each wing forms a V-pattern. Oystercatchers get their name from their habit of snatching oysters from slightly open shells. They also use their powerful bills to open mollusks and to sort through heavy shells in search of food. The oystercatcher needs extensive sandbars and mudflats for feeding and sand or shell-covered beaches free from predators and human disturbance for nesting. The birds usually nest in shallow depressions scraped out of sand, in areas surrounded by water, since they are very sensitive to disturbance and susceptible to mammalian predators. Unfortunately the availability of safe nesting places is declining. Florida Oystercatchers are best spotted in Apalachicola Bay, Tampa Bay, and the Cedar Keys.

Florida black skimmer shore birdsBlack Skimmer- Black skimmers “skim” the surface of the water with black-tipped bright red bills. The lower half of the bill is longer than the upper, allowing it to cut through the water and dip down to grab small fish encountered near the surface. Adult plumage is black above, white below and this striking combination, coupled with the brightly colored bill, makes it easy to spot the birds as they hunt over the water or loaf on the beach with other seabirds and shorebirds. Black skimmers, and least, royal and sandwich terns nest in colonies in the open sand on beaches, sandbars, and dredge material islands. Their nests are built on the ground and often consist of simple scrapes in the sand. (Due to habitat loss, a very small percentage of black skimmers also nest on gravel roofs!) Black skimmers rely on camouflage or group mobbing to protect their nests. Breeding colonies of black skimmers can be found along Florida’s Gulf and Atlantic coasts. Watch for them in the early evening when they actively feed, and scan flocks of loafing birds for this uncommon coastal resident.

least ternLeast Tern- Like all North American terns, the least tern has long, pointed wings and a deeply forked tail. It is the smallest of our terns, and bears outer wing feathers that edge the light-gray wings in black. The breeding adult is gray above, white below, with a black cap. In early spring least terns return from wintering grounds in Latin America. They soon pair up using courtship rituals in which hopeful males offer small fish to prospective mates. The shorebirds nest in very shallow depressions on broad expanses of bare sand, which camouflage the eggs. They lay from mid-April in south Florida to the first of May in the north, and the eggs hatch after 21 days. The young leave the nest in a few days, but don't begin to fly safely until about three weeks later. Populations of least terns sank after the turn of the century, when they were hunted to harvest their feathers to decorate women's hats. Not only are the birds extremely susceptible to nest disturbance, they have lost extensive nesting habitat to beach development and increased human activity there. Least terns are colony nesters, meaning they nest in a group, which allows them to exchange information about food sources, as well as to detect and mob predators. An entire colony can be easily destroyed by predation by red foxes, raccoons, dogs and house cats, by human trampling, or by catastrophic storms.

wading black-necked stilt shorebirds in FloridaBlack-Necked Stilt- With its black and white plumage, long, thin red legs, and long neck, the Black-necked Stilt is both striking and delicate in appearance. It is a medium-sized shorebird with a black needle-like bill, black or dark brown upperparts, and a white breast. The iris is red, and there is a white spot above the eye. Breeding males have glossy black wings, back, and back of neck, and a pink tinge on the breast. Non-breeding males lack the glossiness and pink tinge. Adult females have a brown tinge to the back. Juveniles have brown upperparts with buff feather margins, and a white trailing edge to the wing in flight. Five species of rather similar-looking stilts are recognized in the genus Himantopus. They have the second-longest legs in proportion to their bodies of any bird, exceeded only by flamingos. This bird's habitat includes  salt ponds, rice fields, shallow lagoons, and mangrove swamps.  Black-necked Stilts most often consume aquatic invertebrates. They also sometimes eat tadpoles, tiny fish, and seeds of aquatic plants. Pairs form on wintering grounds, during migration, or on breeding grounds; pairs remain monogamous throughout the breeding season. Both sexes choose the nest site, which is often on a small island in the marsh.
