Revision of Late Pleistocene and Holocene Galliformes Fauna from the Crimean Mountains

The Late Pleistocene and Holocene Galliformes faunas from the Crimean Mountains included seven species of birds belonging to the families Phasianidae and Tetraonidae: Phasianus colchicus, Alectoris chukar, Perdix perdix, Coturnix coturnix, Lyrurus tetrix, Lagopus mutus, and Lagopus lagopus. The habitation of Gallus representatives in the Crimea in the Late Pleistocene has not been confirmed. Representatives of the family Phasianidae were present in the Crimean fauna at least for most of the Late Pleistocene. All of them survived until the Late Holocene. Pheasants became extinct around the eighteenth century, and the rock partridge seems to have disappeared only in the first half of the twentieth century. The species were restored in the Crimea in the second half of the twentieth century. Gray partridges were common resident birds of the Crimean Mountains throughout the Late Pleistocene and Holocene. Quail was not a numerous breeding species of the Crimean Mountains at the same time, but mass migration of this species through the Crimea appeared only at the end of the Late Pleistocene and evolved over the Holocene warming. Species of Tetraonidae appeared in the fauna of the Crimea long before the beginning of the cold-phase maximum of the last glaciations but no later than 28000 years ago and became extinct in the Early Holocene warming but no later than 9000 years ago.
