sp\u00e9cifiques<\/strong><\/p>\n
L<\/strong>e pilet est un canard de taille moyenne, d\u2019une longueur de 51 \u00e0 66 cm (hors rectrices centrales) pour une envergure de 80 \u00e0 95 cm. Les m\u00e2les p\u00e8sent de 700 \u00e0 1100 g, les femelles de 500 \u00e0 900 g. C\u2019est un oiseau \u00e0 la silhouette tr\u00e8s \u00e9lanc\u00e9e, poss\u00e9dant un cou, une t\u00eate et un bec longs. Chez le m\u00e2le, les rectrices centrales peuvent d\u00e9passer le reste de la queue de 10 cm. Elles sont sensiblement plus longues chez les canes pilet que chez les femelles des autres esp\u00e8ces trait\u00e9es ici.[\/vc_column_text][vc_column_text]En plumage nuptial, le m\u00e2le a la t\u00eate et la nuque brun-chocolat \u00e0 refl ets violets, une bande blanche remontant le long du cou jusqu\u2019\u00e0 l\u2019arri\u00e8re des joues. Le dessus et les fl ancs sont vermicul\u00e9s de gris et blanc, la poitrine et le ventre paraissent blancs. Le dessus et le dessous de la queue sont noirs. Les femelles et les jeunes sont brun assez clair. Les femelles en plumage de type adulte ont du roux sur la t\u00eate, le dos et les scapulaires. Le trait oculaire est inexistant ou peu perceptible. Le bec du m\u00e2le est bicolore noir et bleu, ces deux couleurs nettement d\u00e9limit\u00e9es. Chez la femelle, il est gris et bleu fonc\u00e9, confus\u00e9ment m\u00e9lang\u00e9s. Les pattes sont gris-bleu \u00e0 gris fonc\u00e9.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/3″][vc_custom_heading text=”Canard pilet (Anas acuta)” font_container=”tag:h2|text_align:right|color:%23000000″][vc_column_text]Le miroir des m\u00e2les est vert iridescent (parfois violet), bord\u00e9 ant\u00e9rieurement d\u2019une barre cannelle et post\u00e9rieurement d\u2019une barre noire et blanche. Celui des femelles est brun bronze, bord\u00e9 ant\u00e9rieurement d\u2019une barre cr\u00e8me \u00e0 cannelle et post\u00e9rieurement d\u2019une barre blanche.<\/p>\n
D\u00e9termination du sexe et de l\u2019\u00e2ge <\/strong><\/p>\n
Il est pr\u00e9f\u00e9rable de d\u00e9terminer le sexe avant l\u2019\u00e2ge. L\u2019examen alaire portera sur la premi\u00e8re r\u00e9mige tertiaire, les couvertures sous-alaires, les petites et moyennes couvertures susalaires, les grandes couvertures tertiaires (crit\u00e8re valable seulement avant la mue nuptiale pour les femelles).
\nLa distinction des sexes se fait au premier coup d\u2019oeil, \u00e0 la couleur des petites et moyennes couvertures. Il est \u00e9galement tr\u00e8s ais\u00e9 de d\u00e9terminer l\u2019\u00e2ge des m\u00e2les par la seule observation de ces m\u00eames couvertures, sous r\u00e9serve de ne pas confondre l\u2019\u00e9claircissement fr\u00e9quent (par abrasion) de la bordure des petites et moyennes couvertures des m\u00e2les adultes avec le v\u00e9ritable liser\u00e9 p\u00e2le qui borde celles des m\u00e2les juv\u00e9niles.
\nDans certains cas, la d\u00e9termination de l\u2019\u00e2ge des femelles peut s\u2019av\u00e9rer d\u00e9licate. Si les grandes couvertures tertiaires de type juv\u00e9nile ont d\u00e9j\u00e0 \u00e9t\u00e9 remplac\u00e9es par des plumes nuptiales, elle reposera notamment sur la forme et le motif des taches \u00e9ventuellement pr\u00e9sentes sur les petites ou moyennes couvertures. Or, des femelles adultes peuvent pr\u00e9senter une ou deux taches de type plut\u00f4t juv\u00e9nile et vice-versa ; la d\u00e9termination est alors une question de proportion entre les deux types.
\nEn cas de doute et si on dispose de l\u2019oiseau entier, on recherchera des crit\u00e8res non alaires : forme des rectrices et taches sur le bec, pr\u00e9sence ou non d\u2019une bourse de Fabricius pour les oiseaux morts.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_single_image image=”9518″ img_size=”full” alignment=”center” css_animation=”fadeIn”][vc_row_inner][vc_column_inner width=”1\/3″][vc_single_image image=”9517″ img_size=”medium” alignment=”center” css_animation=”top-to-bottom”][vc_column_text] $\"\"$ \u00a0Premi\u00e8re r\u00e9mige tertiaire <\/strong><\/p>\n
