Dapres moi c'est brun sur sa tete ^-^

spour ça que je pense que c'est une femelle ou un juvénile ( un jeune) parce qui'll a l"aire plutot brun je pensais que c'etait un bruant en premier XD

Haha! Oui il se peut tres bien quil soit juvenile aussi! ;)

I thought of that but it seem a bit to small to be a sparrow and usually redpoll are a bit more common here than chipping, thought I must admit that I cannot bet that it's indeed a redpoll you may be right.

and I don,t know way in english you call every little bird sparrow XD, because house sparrow and chipping sparrow are not even in the same familly XD, chipping are in the same familly as white-crowned, and white-throated sparrow etc.

indeed, but some can only have a really small spot on the throat, on that pic I cannot really saw it so if it got one it must be really small size of the spot can change, (maybe because of the age I dunno)
but for the beak I already saw some picture of em with darker beak, but like I said, It could be a chipping sparrow, but it would be odd cauz I rarely so them here that why my guess when to a not really colored female or juvenil redpoll XD because I know that they are more colored than that usualy
