Le Canard carolin<\/strong> ou Canard branchu<\/strong> (Aix sponsa<\/em>) est l’une des deux esp\u00e8ces du genre Aix<\/em>. Il doit son nom \u00e0 la Caroline, \u00c9tats des \u00c9tats-Unis o\u00f9 les premiers sp\u00e9cimens furent captur\u00e9s.<\/p>\n

Le canard carolin mesure environ les trois-quarts de la taille d’un canard colvert, soit environ 50 cm<\/abbr> pour une envergure de 75 cm<\/abbr>. Le m\u00e2le a un plumage vivement color\u00e9 qui fait que l’esp\u00e8ce est souvent d\u00e9tenue en captivit\u00e9, la femelle est, quant \u00e0 elle, beaucoup plus terne. Chez l’adulte, la masse avoisine les 850 grammes.<\/p>\n

R\u00e9partition g\u00e9ographique :<\/p>\n

  • habitat permanent<\/li>\n
  • zone d’hivernage<\/li>\n
  • nidification<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

    Cette esp\u00e8ce se rencontre principalement sur les c\u00f4tes est et ouest des \u00c9tats-Unis, mais aussi au Mexique et jusqu’au Canada en p\u00e9riode de reproduction.<\/span><\/p>\n

    Cet oiseau fr\u00e9quente les zones bois\u00e9es le long des rivi\u00e8res, les lacs et marais de son aire de r\u00e9partition.<\/span><\/p>\n

    Le canard carolin se nourrit dans son milieu naturel de plantes aquatiques, de graines et fruits ainsi que d’insectes. En captivit\u00e9, souvent maintenu avec d’autres esp\u00e8ces ayant de l\u00e9g\u00e8res diff\u00e9rences alimentaires, ou m\u00eame en sp\u00e9cifique, il se nourrit et s\u2019accommodera \u00e9galement de salades, et d’un certain nombre d’autres l\u00e9gumes simples communs, souvent fournis en compensation des plantes et autres mets rencontr\u00e9s dans son milieu.\"\"<\/span><\/p>\n

    Les m\u00e2les arborent tout au long de l’ann\u00e9e un plumage terne presque semblable \u00e0 celui des femelles. Mais quand vient la p\u00e9riode de reproduction, \u00e0 la saison des amours, le canard carolin se pare d’un plumage somptueusement color\u00e9. Ce magnifique oiseau se reproduit dans les r\u00e9gions de l’Ontario et du Qu\u00e9bec<\/span><\/p>\n

    Cette esp\u00e8ce a besoin d’arbres pour nidifier puisque les \u0153ufs sont pondus en milieu naturel dans une cavit\u00e9 d’arbre. Le nid est souvent situ\u00e9 \u00e0 proximit\u00e9 de l’eau afin de permettre aux canetons d’y sauter d\u00e8s leur 2e<\/sup><\/abbr> jour pour rejoindre leur m\u00e8re qui les appelle d’en bas. En captivit\u00e9 un simple nichoir artificiel adapt\u00e9 \u00e0 sa taille et semblable \u00e0 ce qu’il rencontre dans son milieu sera adopt\u00e9 sans trop de difficult\u00e9.<\/span><\/p>\n

    La femelle pond g\u00e9n\u00e9ralement entre neuf et une quinzaine d\u2019\u0153ufs. La couv\u00e9e varie entre 28 et 30 jours.<\/span><\/p>\n

    La pose de nichoirs a permis au canard carolin de voir ses populations se d\u00e9velopper aux \u00c9tats-Unis apr\u00e8s une chasse abusive au d\u00e9but du XX<\/span>e<\/sup><\/abbr> si\u00e8cle. En cause, la r\u00e9colte de ses plumes pour la confection de fausse mouche pour la p\u00eache et de chapeau. L’esp\u00e8ce a \u00e9t\u00e9 introduite dans divers pays d’Europe mais ne s’est pas aujourd’hui (2014) aussi bien acclimat\u00e9e que par exemple le Canard mandarin.<\/span><\/p>\n

    Un certain nombre de vari\u00e9t\u00e9s de s\u00e9lection sont blondes et\/ou blanches et sont consid\u00e9r\u00e9es comme domestiques.<\/p>\n<\/div>\n
