L’oie \u00e0 t\u00eate barr\u00e9e<\/strong> (Anser indicus<\/strong><\/em>), parfois appel\u00e9e oie tigr\u00e9e<\/strong> est une esp\u00e8ce d’oiseaux de la famille des Anatidae.<\/p>\n

L’oie \u00e0 t\u00eate barr\u00e9e mesure entre 71 et 78\u00a0cm<\/abbr> de longueur pour une envergure de 140 \u00e0 160 cm et une masse de 2 \u00e0 3\u00a0kg<\/abbr>. Elle est facilement reconnaissable gr\u00e2ce \u00e0 sa t\u00eate blanche et sa barre blanche sur le c\u00f4t\u00e9 du cou qui contrastent avec l’arri\u00e8re du cou noir et les deux barres noires sur la t\u00eate. Le reste du plumage est gris. Le bec et les pattes sont jaunes. La femelle est relativement plus petite que le m\u00e2le.<\/p>\n

C’est l’un des oiseaux volant le plus haut. Elle a \u00e9t\u00e9 observ\u00e9e \u00e0 plus de 10\u00a0km<\/abbr> d’altitude. Le rapport de sa surface alaire \u00e0 son poids est l\u00e9g\u00e8rement sup\u00e9rieur \u00e0 celui des autres oies, ce qui pourrait l’aider \u00e0 voler plus haut.<\/p>\n

\"\"<\/p>\n

Cette esp\u00e8ce se rencontre dans le centre de l’Asie (essentiellement en Mongolie et en Chine) o\u00f9 elle fr\u00e9quente les lacs de haute montagne. L’oie \u00e0 t\u00eate barr\u00e9e est une esp\u00e8ce migratrice qui passe l’hiver dans le nord de l’Inde et les r\u00e9gions voisines.<\/p>\n

La plus grande colonie a \u00e9t\u00e9 observ\u00e9e sur le lac Tso Moriri\u00a0(en)<\/span> au Ladakh.<\/p>\n

Une population introduite s’est d\u00e9velopp\u00e9e en Su\u00e8de\u00a0; d’autres sp\u00e9cimens sont acclimat\u00e9s dans les parcs et jardins en Europe, et ils sont fr\u00e9quents dans les parcs zoologiques.<\/p>\n

C’est une esp\u00e8ce gr\u00e9gaire aussi bien en migration que durant la p\u00e9riode de nidification. La reproduction d\u00e9bute au mois d’avril, les oiseaux quittant les aires de reproduction \u00e0 partir du mois d’ao\u00fbt. Durant la migration, elle survole l’Himalaya, exploit seulement \u00e9gal\u00e9 par la grue demoiselle3<\/sup>,<\/sup>4<\/sup>. L’oie \u00e0 t\u00eate barr\u00e9e dispose d’une multitude d’adaptations physiologiques qui rendent possible cette travers\u00e9e bisannuelle. Gr\u00e2ce aux particularit\u00e9s de son h\u00e9moglobine qui fixe tr\u00e8s fortement l’oxyg\u00e8ne, elle peut fournir l’effort n\u00e9cessaire aux migrations dans un air rar\u00e9fi\u00e9 en oxyg\u00e8ne. L’h\u00e9moglobine de son sang a une plus haute affinit\u00e9 \u00e0 l’oxyg\u00e8ne que celle des autres oies. Des \u00e9tudes ont montr\u00e9 que sa respiration est plus efficace dans des conditions pauvres en oxyg\u00e8ne et qu’elle est capable de r\u00e9duire les pertes thermiques.<\/p>\n

\"\"<\/p>\n

La population est comprise entre 52\u00a0000 et 62\u00a0000 individus et ne semble pas menac\u00e9e<\/p>\n

Peut observations au bord de la mer Noire, sure des exemplares echappe du zoo.<\/p>\n
