Gruiformes

Rallus

The Mangrove Rail (R. longirostris) and King Rail (R. elegans) are in a long zone of secondary contact in the eastern USA along which hybridization occurs (Maley & Brumfield, 2013).

Several hybrids have been produced in captivity by means of artificial insemination, for example White-naped crane (G. vipio) x Siberian Crane (G. leucogeranus) hybrids (Maksudov & Panchenko, 2002). For experimental purposes (DNA fingerprinting protocol), hybrids were also obtained between Siberian Crane and Sandhill Crane (G. canadensis) (Tokarskaya et al., 1994).

A population genetic study of Sarus Crane (G. antigone) revealed the Indian and eastern subspecies represent major breeding groups and that the Myanmar population probably resides in an introgression zone between them (Jones, Barzen & Ashley, 2005).
