🐦Corn Crake

Crex crex (Linnaeus, 1758)

Le Râle des genêts (Crex crex) ou Roi caille, est une espèce d'oiseaux de l'ordre des Gruiformes et de la famille des Rallidae, la seule représentante du genre Crex. Il s'agit d'un oiseau migrateur nichant au sol. Il est assez farouche, mais est connu pour son cri nocturne (« crex crex »). Il établit son nid à la mi-mai dans les prairies de fauche en Europe. Sa nidification dure deux mois. Durant l'hiver septentrional, il migre dans le sud de l'Afrique. Autrefois commune, l'espèce a subi un déclin marqué dans la plupart des pays d'Europe occidentale depuis plus d'un siècle, victime de la disparition de son habitat et de l'intensification agricole entraînant une fauche des prés précoce fatale aux jeunes voire aux adultes eux-mêmes.
