Les r\u00e2les des gen\u00eats sont un peu plus grands qu’un merle et sont jaune-brun fonc\u00e9, avec des barres sombres sur le dos, des flancs rouge\u00e2tres et un ventre gris.\nLes poussins, \u00e0 l’\u00e9closion, ont un duvet noir. <\/p>\n\n\n\n

Les m\u00e2les \u00e9mettent un cri fort et distinctif, le \u00ab\u00a0crex crex\u00a0\u00bb, qui peut \u00eatre entendu jusqu’\u00e0 1 km de distance.\nEsp\u00e8ce timide, les r\u00e2les des gen\u00eats sont rarement vus et sont mieux localis\u00e9s gr\u00e2ce \u00e0 ce cri, qui est surtout entendu la nuit. <\/p>\n\n\n\n

Les r\u00e2les des gen\u00eats se rencontrent g\u00e9n\u00e9ralement dans la v\u00e9g\u00e9tation haute (20 cm) des champs de foin et d’ensilage, des p\u00e2turages pauvres et des peuplements d’esp\u00e8ces herbac\u00e9es telles que l’iris jaune et les orties.\nIl est omnivore et se nourrit principalement d’insectes, d’escargots, de limaces et de vers, mais aussi de graines. <\/p>\n\n\n\n

Les r\u00e2les des gen\u00eats sont des visiteurs d’\u00e9t\u00e9 qui se reproduisent en Irlande d’avril \u00e0 septembre et migrent vers l’Afrique pour l’hiver.\nLe territoire d’un m\u00e2le peut parfois englober plusieurs nids, cr\u00e9ant ainsi des concentrations locales d’oiseaux nicheurs.\nLe nid est construit sur le sol \u00e0 partir de tiges et de feuilles.\nLes femelles pondent de 8 \u00e0 12 \u0153ufs et produisent g\u00e9n\u00e9ralement deux couv\u00e9es par an.\nLes nids sont difficiles \u00e0 localiser et se trouvent g\u00e9n\u00e9ralement dans un rayon de 250 m autour des m\u00e2les qui appellent. <\/p>\n\n\n\n

Les crachats sont migrateurs et hivernent en Afrique subsaharienne, principalement dans les pays du sud-est (Afrique du Sud, Zimbabwe, Zambie et Tanzanie), o\u00f9 les habitats de prairies sont favoris\u00e9s.<\/p>\n\n\n\n

Les r\u00e2les des gen\u00eats commencent \u00e0 revenir sur leurs lieux de reproduction en avril et en mai.\nComme la plupart des r\u00e2les, ils sont discrets et on les voit rarement \u00e0 d\u00e9couvert.\nTout au long du cycle de reproduction, ils ont besoin d’un couvert continu de v\u00e9g\u00e9tation haute, d’au moins 20 cm de hauteur, qui conserve une structure ouverte – la v\u00e9g\u00e9tation qui devient trop dense \u00e0 mesure que la saison avance a tendance \u00e0 \u00eatre \u00e9vit\u00e9e. <\/p>\n\n\n\n

Les m\u00e2les attirent les partenaires gr\u00e2ce \u00e0 leur chant rauque et puissant, appelant le plus souvent pendant plusieurs heures \u00e0 partir de minuit, peu apr\u00e8s leur arriv\u00e9e et jusqu’\u00e0 la mi-juillet, lorsque l’activit\u00e9 d’appel diminue.\nIls forment un couple avec les femelles pendant la ponte, p\u00e9riode pendant laquelle ils chantent moins fr\u00e9quemment la nuit. <\/p>\n\n\n\n

La femelle est la seule \u00e0 s’occuper de la couv\u00e9e de 8 \u00e0 12 \u0153ufs dans un nid peu profond au sol, dissimul\u00e9 dans la v\u00e9g\u00e9tation haute.\nLes poussins de la premi\u00e8re couv\u00e9e sont accompagn\u00e9s par la femelle pendant environ 12 jours, puis la femelle abandonne les poussins pour pondre une deuxi\u00e8me couv\u00e9e. <\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
