​Rails, Common gallinule, and Coots

The American coot is an uncommon breeder in Pennsylvania but a common to abundant migrant. The American coot is dark gray with a bone white bill. Noisy and gregarious, coots often form flocks. They eat mainly plant foods but also take insects, fish, tadpoles, snails, crayfish, and the eggs of other birds. They feed like ducks, upending in shallow water; dive to get at plants; and graze on land. To take off from the water they must first run along on the surface to build up speed. Coots need extensive marshlands for breeding. In Pennsylvania they nest mainly in the northwest around Pymatuning Reservoir and in other wetland areas. During mild winters when lakes and rivers don't freeze over, many coots may winter in Pennsylvania.

The black rail is a slate-colored, sparrow size bird. It breeds in tidal marshes from New Jersey to Florida, and in inland marshes south of the Great Lakes; recent studies suggest 0-5 black rail nests occur in Pennsylvania each year. The Black rail is a federally threatened species. Marsh visiting birdwatchers sometimes glimpse black rails during the spring and fall migration. The species winters in the southern United States, Central America, and the Caribbean Islands.

The Common gallinule was formerly called the common or Florida gallinule and common moorhen. It sounds an assortment of cackles, clucks, croaks, and squawks that help make the marsh a magical, spooky place at night. Common gallinules are mainly dark gray, with red bills. While swimming they make pumping motions with their heads. They favor deeper water than the rails and often swim among water lilies and pondweeds. Common gallinules feed on buds, leaves, and seeds of water plants, fruits and berries of dry land plants, and a variety of insects and other invertebrates. They nest mainly in thick cattails. In Pennsylvania, moorhens nest around Pymatuning Reservoir and Conneaut Marsh and in scattered wetlands elsewhere in the state. Common gallinules migrate in spring and fall to wintering areas from coastal North Carolina southward.

The king rail is one of Pennsylvania's rarest breeding birds and has been designated a state endangered species. Its breeding range is centered on the Southeastern and Midwestern states. The king rail is reddish in color and about the size of a chicken. The largest of the North American rails, it can prey on frogs and small fish, as well as many aquatic insects.

The sora (Porzana Carolina) is the most widespread and abundant of the North American rails. It breeds across Canada and the northern United States, including Pennsylvania, and winters in the southern states and Central and South America. With its short bill, the sora eats primarily seeds. The species' song has been described as "an explosive, descending musical whinny".

The Virginia rail breeds in wetlands with sedges and cattails in scattered locations across Pennsylvania. Mainly nocturnal, it eats insects and their larvae, including beetles, flies, and dragonflies. Virginia rails build a nest on a platform of cattails, grasses, and reeds, in a dry zone of the marsh, where living vegetation may form a canopy overhead.

Ornithologists frequently describe the yellow rail as one of the most secretive birds in North America. This yellowish species breeds mainly in southern and central Canada and winters along the Atlantic and Gulf coasts. In Pennsylvania the yellow rail is a rare migrant, passing through in late April and early May and again in September and early October. The species eats a variety of insects as well as many seeds. The Yellow Rail was a game species for many years but is no longer legally hunted in the United States or Canada.
