  1. Rails Biology, Ecology, and Management

  2. Classification Kingdom Animalia Phylum Chordata Class Aves Order Gruiformes Family Rallidae Coturnicops Laterallus Rallus Aramides Porzana Cyanolimnas Pardirallus

  3. Characteristics of Family • Small to medium-sized waterbirds • Shy, mostly solitary • Laterally compressed bodies • Bill varies, usually slightly decurved • Short tail

  6. Rails of Kentucky There are 4 found in Kentucky! Coturnicops noveboracensis Yellow Rail Rallus elegans *King Rail Rallus limicola Virginia Rail Porzana carolina Sora *Argued whether found in Kentucky or not.

  7. Sora Porzana carolina

  8. Breeding Range of Sora

  9. Wintering Range

  10. Identification • Length: 6.75 inches • Wingspan: 12.5 inches • Body is small and chunky • Short-tail which is cocked during walk and shows white undertail coverts • Wings are rounded • Ground-dwelling • Short thick, yellow bill • Rarely flies • Sexes similar • Black face mask

  11. Habitat and Foraging • The sora occupies a freshwater wetland habitat throughout its range; it also uses salt marshes while overwintering. • The preferred habitat provides considerable cover for breeding soras, and consists mostly of freshwater wetlands with stands of cattail, sedges, and other tall wetland plants. • Diet consists mainly of seeds, insects and snails.

  12. Breeding • Nests are woven into a shallow basket from dead emergent wetland vegetation, and attached to stalks of dense, live vegetation. • Nests are generally placed over or adjacent to water, occasionally occurring in dry environments such as willows or grassy habitat near water's edge. • The average clutch size ranges from 10-12 (sometimes 6-18) brown, spotted eggs, occasionally laid in two layers to accommodate such large numbers in a relatively small nest. • Incubation by both parents lasts from 18-20 days, and is initiated with the laying of the first few eggs. • Young hatch asynchronously due to incremental stages of incubation. • Young soras leave the nest shortly after hatching, and mainly forage themselves, having been taught by a parent. • At 21-25 days young soras fledge and gain independence from their parents' care.

  13. Management Concerns • Due to loss of wetland habitat, sora’s range has declined. • Although population is considered abundant, further depletion of wetlands is a threat.

  14. Management • Wetland loss and degradation should be avoided. • Long-term protection of wetlands. • Wetland complexes would allow for variation of water levels and therefore is recommended. • Protection of mudflats, sandbars, and meadows where soras forage.

  15. Virginia Rail Rallus limicola

  16. Breeding Range of Virginia Rail

  17. Wintering Range

  18. Identification • Length: 7.5 inches • Wingspan: 14 inches • Fairly small chunky body • Short-tailed • Round-winged • Ground-dwelling • Long, slightly decurved bill • Rarely flies • Sexes similar • Red eyes

  19. Habitat and Foraging • Rails prefer freshwater marshes and wetlands. • The most important features of their habitat include shallow water, an emergent cover of cattails and bulrushes, and a high invertebrate abundance in the water. • They forage in standing water, moist soil, and mudflats. • Using its long, curved bill, the Virginia Rail probes the muddy soils and shallow waters of its habitat for food. • It most often consumes small aquatic invertebrates, such as beetles, spiders, snails, and true bugs. • In the winter, when these foods are less available, it also eats aquatic plants and seeds.

  20. Breeding • Pairs are thought to be monogamous. • Either males or females may initiate bond formation, which spans a period of one or two weeks. • During this time, pairs engage in mutual preening, courtship feeding, copulation, and defense of territory. • Nests are built in May. • Both the male and female build the nest, which is located in marshes containing cattails and bulrushes. • A canopy is often built above the nest by bending and weaving adjacent vegetation. • Along with the nest, numerous "dummy" nests are built within their territory. • Clutch size varies greatly with geography, but the average size seems to be 8-9 eggs. • Both sexes incubate, and the young hatch about 19 days after incubation begins. • Young are covered with black down and development progresses rapidly; young begin to run down the nest ramp to drink and swim only 11 hours after hatching.

  21. Management Concerns • Degradation of its wetland habitat may have caused a decrease in populations. • Although populations are considered stable, this is not really known due to the fact that not a lot of research has been done on this species.

  22. Management • Protection of wetlands is important. • Since they like shallow waters, water manipulation is beneficial. • The management of wetlands helps to manage birds.

  23. Yellow Rail • Coturnicops noveboracensis

  24. Breeding Range of Yellow Rail

  25. Wintering Range • Not much is known about wintering range of this species.

  26. Identification • Length: 5 inches • Small, chunky body. • Short-tailed • Round-winged, • Ground-dwelling • White secondaries • Short, thick, yellow bill • Black upperparts with thin white fringes and broad buffy streaks • Dark crown, yellow supercilium, and dark eyeline • Breast buffy yellow • Flanks and undertail coverts barred black and white • Rarely flies • Sexes similar

  27. Habitat and Foraging • Yellow Rails prefer moist areas, with little or no standing water. • Their preferred summer habitat includes marshy areas with low ground cover, grassy flood plains, wet meadows, and bog areas with low vegetation. • During migration, they stop over in rice fields, dry hay fields or cereal fields. • In winter, the birds can be found in coastal marshes and rice fields. • Eats on fruits and seeds.

  28. Breeding • Nest usually constructed in dense clump of marsh grasses or fallen or dead grasses often a few inches above flooded soil or bottom just touching. • Cup nest is woven from fine dry grasses, some sedge. • Clutch size = 7-10 eggs, rich yellow-buff color, usually speckled or densely spotted at large end with red-brown • Incubation, presumed by female alone, approx. 18 days. • Incubation begins with last egg. • Young are precocial, covered with black down, and possess a 'wing claw' on the manus facilitating movement through dense vegetation

  29. Management Concerns • Degradation of habitat due to draining of wetlands. • Thickening of sedges and other vegetation may reduce the reproduction due to lack of adequate nesting sites.

  30. Management • Protection of wetlands. • Periodic burnings to thin out vegetation so that adequate nesting sites are available.
