Grus (bird)


Grus is a genus of large birds in the crane family.
The genus Grus erected by the French zoologist Mathurin Jacques Brisson in 1760. The name Grus is the Latin word for "crane". The German ornithologist Peter Simon Pallas was sometimes credited with erecting the genus in 1766 but the International Commission on Zoological Nomenclature ruled in 1956 that Brisson should have priority.
The genus formerly included additional species. A molecular phylogenetic study published in 2010 found that the genus Grus, as then defined, was polyphyletic. In the resulting rearrangement to create monophyletic genera, the sandhill crane, the white-naped crane, the sarus crane and the brolga were moved to the resurrected genus Antigone that had been erected by the German naturalist Ludwig Reichenbach in 1853. The Siberian crane was moved to the resurrected monotypic genus Leucogeranus.

Species

The genus contains eight living species:
ImageScientific nameCommon nameDistribution
Grus carunculataWattled craneEastern and southern Africa
Grus paradiseaBlue craneSouthern Africa
Grus virgoDemoiselle craneCentral Eurasia, ranging from the Black Sea to Mongolia and northeastern China. There is also a small breeding population in Turkey.
Grus japonensisRed-crowned craneSiberia, northeastern China, Hokkaidō, the Korean Peninsula, and occasionally in northeastern Mongolia.
Grus americanaWhooping craneNorth America
Grus grusCommon craneEurope, Asia and northern Africa
Grus monachaHooded craneSouth-central and south-eastern Siberia, Mongolia, China.
Grus nigricollisBlack-necked craneThe Tibetan Plateau and remote parts of India and Bhutan.

The HBW/BirdLife and Clements checklists place the demoiselle crane and blue crane in the genus Anthropoides, and the wattled crane in the monospecific genus Bugeranus, leaving only the red-crowned, whooping, common, hooded, and black-necked cranes in the genus Grus.
The Cuban flightless crane, which became extinct in the Pleistocene, was formerly assigned to the genus Grus.

Fossil record

The fossil record of the genus stretches back some 12 million years or so. A considerable number of prehistoric species are known, with the oldest, Grus miocaenicus perhaps not a crane but a junior synonym of the swimming-flamingo Palaelodus ambiguus;. The Late Pleistocene Mediterranean Grus primigenia was hunted by Stone Age humans.Grus afghana - doubtfully distinct from G. penteleci

Several other fossil gruiforms are now considered not to belong here. "Grus" prentici is now in Paragrus, "Grus" princeps, "Grus" excelsa and "Grus" hordwellianus are placed in Palaeogrus, and "Grus" excelsa in Balearica. "Grus" marshi belongs in Aletornis.
More uncertain is the position of Probalearica from Golboçica and maybe elsewhere. It is usually regarded a nomen dubium but might belong into Grus. "Grus" conferta is apparently too different from the modern genus to be placed herein, but its affiliations are not well resolved.
