Siberian crane
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".
