Dendrocygne \u00e0 face blanche (Dendrocygna viduata)<\/p>\n
Autres noms : Canard arboricole \u00e0 face blanche<\/p>\n
Aire de r\u00e9partition : Le canard \u00e0 face blanche se rencontre dans les zones tropicales d'Am\u00e9rique centrale et d'Am\u00e9rique du Sud, ainsi qu'en Afrique subsaharienne.<\/p>\n
Habitat\u00a0: Le canard \u00e0 face blanche est un oiseau aquatique qui pr\u00e9f\u00e8re les plans d'eau douce calmes et ouverts tels que les lacs, les r\u00e9servoirs, les marais et les berges des rivi\u00e8res. Il \u00e9vite g\u00e9n\u00e9ralement les zones bois\u00e9es, mais niche dans les zones \u00e0 v\u00e9g\u00e9tation dense. Le nid est construit \u00e0 partir de v\u00e9g\u00e9taux, soit au-dessus, soit pr\u00e8s de l'eau.<\/p>\n
Description : Comme son nom l'indique, cette esp\u00e8ce a la face blanche, mais l'arri\u00e8re de la t\u00eate est noir. Sa poitrine est couleur rouille et ses flancs sont barr\u00e9s de noir et de blanc. Ses pattes et son bec sont gris. Le m\u00e2le et la femelle sont de couleur similaire, bien que les m\u00e2les soient g\u00e9n\u00e9ralement l\u00e9g\u00e8rement plus petits que les femelles. La plupart du temps, les \u00e9rismatures \u00e0 face blanche sont de puissants aviateurs, mais elles subissent une br\u00e8ve mue apr\u00e8s la saison de reproduction. Elles ne peuvent pas voler pendant cette p\u00e9riode et sont particuli\u00e8rement vuln\u00e9rables aux pr\u00e9dateurs.<\/p>\n
Situation \u00e0 l'\u00e9tat sauvage\u00a0: Les \u00e9rismatures \u00e0 face blanche sont abondantes \u00e0 l'\u00e9tat sauvage. Elles vivent en bandes et des groupes de 1\u00a0000 individus ou plus ont parfois \u00e9t\u00e9 observ\u00e9s ensemble. L'Union internationale pour la conservation de la nature (UICN) classe cette esp\u00e8ce dans la cat\u00e9gorie \u00ab\u00a0Pr\u00e9occupation mineure\u00a0\u00bb. Contrairement \u00e0 de nombreuses autres esp\u00e8ces de sauvagine, la population sauvage d'\u00e9rismatures \u00e0 face blanche est en croissance, gr\u00e2ce \u00e0 la construction de cours d'eau artificiels et \u00e0 la culture de c\u00e9r\u00e9ales dans les zones o\u00f9 elles vivent naturellement.<\/p>\n
Situation en aviculture : Il existe des populations sauvages en bonne sant\u00e9 et le canard \u00e0 face blanche est populaire aupr\u00e8s des personnes qui aiment \u00e9lever des oiseaux aquatiques sauvages. Il y en a donc \u00e9galement un nombre abondant \u00e9lev\u00e9 en captivit\u00e9.<\/p>\n
Saison de reproduction : La reproduction commence avec la saison des pluies.<\/p>\n
Taille de la couv\u00e9e : 8 \u00e0 12 \u0153ufs<\/p>\n
P\u00e9riode d'incubation : 26 \u00e0 28 jours<\/p>\n
Notes diverses\u00a0: Les \u00e9rismatures \u00e0 face blanche appartiennent au genre Dendrocygna, aussi appel\u00e9 \u00ab\u00a0oiseaux siffleurs\u00a0\u00bb, qui comprend huit esp\u00e8ces. On les appelle \u00ab\u00a0dendrocygnes siffleurs\u00a0\u00bb en raison de leur cri distinctif, d\u00e9crit comme \u00ab\u00a0r\u00e9solument diff\u00e9rent de celui d'un canard\u00a0\u00bb. L'\u00e9rismature \u00e0 face blanche se nourrit en barbotant et en pataugeant, g\u00e9n\u00e9ralement la nuit. Il se nourrit principalement de v\u00e9g\u00e9taux, mais aussi d'insectes et de mollusques.<\/p>","protected":false},"excerpt":{"rendered":"
