The International Ornithologists' Union (IOU) recognises 15 species of cranes in four genera. [7] This list does not include hybrid species, extinct prehistoric species, or putative species not yet accepted by the IOU. The cranes are divided into two subfamilies, which diverged from each other around 31 million years ago: Balearicinae ...
Of the four crane genera, Balearica (two species) is restricted to Africa, and Leucogeranus (one species) is restricted to Asia; the other two genera, Grus (including Anthropoides and Bugeranus) and Antigone, are both widespread. [5] [1] Many species of cranes are dependent on wetlands and grasslands, and most species nest in shallow wetlands.

Most have elaborate and noisy courting displays or "dances". Common crane, Grus grus (A) LC; Hooded crane, Grus monacha (A) VU; Sandhill crane, Antigone canadensis LC (ssp. nesiotes and pulla: E)
The genus formerly included additional species. A molecular phylogenetic study published in 2010 found that the genus Grus , as then defined, was polyphyletic . [ 5 ] 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 ...
There are only two suprafamilial clades (natural groups) among the birds traditionally classified as Gruiformes. Rails (), flufftails (Sarothruridae), finfoots and sungrebe (Heliornithidae), adzebills (Aptornithidae), trumpeters (), limpkin (), and cranes compose the suborder Grues and are termed "core-Gruiformes".
