Cuculiformes

The cuculiformes are anatomically close relatives of the Psittaciformes. Like those, they have two former fingers and two posterior fingers, but their legs are less prehensile, with a different musculature. As for their nozzle, his upper part is not mobile, nor hooked, and the nostrils do not carry a wax. The long tail of the cuculiformes account less feathers than that of the psittaciformes.

Systematic

Traditionally, this order is subdivided in 2 families:
  • musophagidés (23 species of Touraco S), currently regarded as formant a particular order: the Musophagiformes,
  • cuculidés , 140 species divided into 5 or 6 subfamilies having statute of family in the classification of Sibley & Monroe.
    • Centropodinés (or centropodidés): Coucal S,
    • Coccyzinés (or coccyzidés): Coulicou S, Tacco S, Piaye S,
    • Crotophaginés (or crotophagidés): ani S and Guira,
    • Cuculinés (or cuculidés): Cuckoo S, Malcoha S, Calobate S and Coua S (constituting the subfamily of the couinés ),
    • Néomorphinés (or néomorphidés): Géocoucou S,
  • opisthocomidés (1 species of Hoazin) formerly integrated into the order of the Galliformes or constituting that of the Opisthocomiformes.
