Rails are small, shy, marshland birds in the family Rallidae, which includes about 129 species. This family has a worldwide distribution, occurring on all continents except Antarctica. Many species of rails occur only on certain remote, oceanic islands, where many of these isolated species have evolved a flightless condition because of the lack of predators. Unfortunately, this characteristic makes these birds extremely vulnerable to predators that were subsequently introduced by humans to the remote habitats of these flightless birds. Consequently, many of the island species are now extinct or endangered.

Species in the rail family have a rather wide range of body and bill shapes. The true rails have a rather long, slender beak, often downward curving. The body of rails that live in marsh habitats is quite compressed laterally, a characteristic that gave rise to the saying, "skinny as a rail." Species that are commonly called rails generally live in reedy marshes, and are relatively l…
Nine species in the rail family occur regularly in North America, primarily in wetland habitats. The American coot (Fulica americana) is widespread and common in marshes and other relatively productive wetlands. This species has a grey body and white beak, with a vividly red frontal lobe at the top of the upper mandible, and red-colored eyes. This species chiefly feeds on aquatic vegetation, which…
Many species of rails that live on remote, oceanic islands have become flightless, because of the lack of natural predators. This is true of various endemic species that are specific to particular islands (that is, they do not occur anywhere else), and also of flightless populations of more wide-ranging species of rails. The benefit of flightlessness to rails living on islands is not totally clear…
