人を惑わす忍者ヒメウソ (A Ninjya seedeater that deceives a person)

2015年12月26日、ニュワス公園とGuazu Metropolitano Parkを散歩した。散歩道近くの木の枝に背中の黒っぽい小鳥が止っていた。 頭部は黒いが頬の部分が白いのでホオジロヒメウソのオスかと思った。
On December 26, 2015, I strolled in Ñu Guazú Park and adjacent Guazu Metropolitano Park. A small bird with blackish back perched on the branch of the tree close to the promenade. I thought whether it was a male Lined seedeater because the head was black and the part of cheeks was white.

頭部は黒いが頬の部分が白いのでホオジロヒメウソのオスかと思った。しかし、背中が焦げ茶色で翼に白いスポットがなく体形もかなり異なる。変わったヒメウソだ、とすれば、忍者のように羽毛模様のバリエーションが多いカワリヒメウソではないか。
I thought whether it was a male Lined seedeater because the head was black and the part of cheeks was white. However, the back is dark brown and the wing does not have a white spot, and the figure is considerably different. This bird is a strange seedeater, and then the bird may be much Variable seedeater that has much variation of the plumage like Ninjya.
