Les Jaseurs bor\u00e9aux ont un plumage tr\u00e8s complexe \u00e0 d\u00e9finir. Il existe quelques diff\u00e9rences entre les femelles, les m\u00e2les et les jeunes.<\/p>\n\n\n

Si la bavette noire se termine de fa\u00e7on tr\u00e8s nette, c’est probablement un m\u00e2le.
On remarquera aussi les fins traits blancs sous les yeux qui continuent jusqu’a la commissure du bec. Ces deniers d\u00e9tails ne prouvent pas le sexe de l’oiseau. Ils seraient communs aux deux sexes.<\/p>\n\n\n

Cet oiseau change de r\u00e9gime alimentaire en hiver, d’insectivore, il passe \u00e0 frugivore, par la force des choses. En effet, dans les r\u00e9gions polaires o\u00f9 il se reproduit, la quantit\u00e9 d’insectes (moustiques) est impressionn\u00e2tes. Par contre en hiver, il se rabat sur les baies qui, si possible ont gel\u00e9.<\/p>\n\n\n

On le voit avec un fruit du tro\u00e8ne dans son bec qu’il va avaler.<\/p>\n\n\n

Les 2 sexes ont une belle huppe que l’oiseau peut redresser ou abaisser \u00e0 souhaits.<\/p>\n\n\n\n
