2015年11月14日、ニュワス公園と北西に接するもう一つの大きい公園であるGuazu Metropolitano Parkの両方を散歩した。 両公園を隔てる川にかかる橋を渡っている時、岸辺の草原に小さなヒメウソが2羽いるのに気付いた。 1羽はフタスジヒメウソのオスとすぐ分かった。もう一羽は薄い焦げ茶色でメスの特徴をしている。2羽には近づいて交流しているような行動が見られたので フタスジヒメウソのオスとメスのようだ。オスとメスの羽毛の模様は同じ種とは思えないほど異なる。
On November 21, 2015, I strolled in Nu Guazu Park and adjacent Guazu Metropolitano Park which was another big park contracted northwest of Nu Guazu Park. When I was crossing the bridge of the river which divides both parks, I noticed two seedeaters in the grassy plain of the bank. One of them was easily identified as a male of Double-collared seedeater. Another one had a female characteristic with light dark brown plumage. They seem to be male and female of Double-collared seedeater because they took an action to communicate each other. The plumages of the male and female are so different that it is hard to identify them as the same species.

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。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。
On December 26, 2015, I strolled in Nu Guazu 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. 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.

2015年11月07日、ニュワス公園とGuazu Metropolitano公園を散歩した。大メトロポリタン公園の緑の遊歩道を歩いていたら 茂みの木の枝に頭部の黒い小さい鳥が止っているのに気付いた。シロハラヒメウソのオスのようだ。近くに姿は似ているが色が地味な小鳥もいた。 この2羽は一緒にいる様子なのでつがいだろうか？ヒメウソのメスは種によらず似ているので判別が困難だ。 公表されている他の写真とも見比べる必要がある。他の写真と比較検討した結果、以前（10月24日）、 撮影したヒメウソがシロハラヒメウソのメスのようだ。

On October 31, 2015, I strolled in Nu Guazu Park and Guazu Metropolitano Park. When I was walking the Green promenade I noticed a small bird with black head perched on the twig of bush. It seemed to be male of the White-bellied seedeater. There was a similar small bird with quiet color near the male bird. These two birds might be pairs since they are together. It is difficult to identify species of seedeater females because they resemble each other. It is necessary to compare with other photos open to public. As a result of having compared it against other photos, the seedeater which I took photos before (Oct. 24, 2015) is the female of White-bellied seedeater.

2015年1月3日、ニュワス公園内を散歩した。以前ヒメウソを見た湖畔の草原に行くと、小さい小鳥の群が動き回っていた。 しばらく静かに見た結果では複数の種類の小鳥がいるようだが、小さい上に草や小枝に隠れて肉眼では区別が難しい。 フタスジヒメウソが草の実を食べている近くにもう一羽の小鳥がいた。体全体が茶色っぽく見えたのでメスかなと思ったが、 写真を見るとそうでもないようだ。若いヒメウソのオスかもしれない。
January 3, 2015, I took a walk in Nu guazu Park. When I went to the grassland near the pond where I saw Seedeater last time, group of small birds were moving around. It seemed there were more than one type of bird after seeing them for a while quietly, but it was difficult to distinguish with the naked eye because they were small and hidden in grass and twigs. There was another bird near the Double-collared seedeater that was eating the grass seed. Although I thought it would be a female seedeater since the entire body looked brownish, it seemed different after looking at the photos. It may be a young male of the seedeater.

2014年11月29日、草原へと続く林を歩いていたら目の前の木の枝に1羽の小さい小鳥が止まった。 この小鳥はくちばしの形からseedeaterと思われる。全身の色が地味なのでメスだが、seedeaterのメスはどの種類も似ているので判定が難しい。 前回Double-collared seedeaterのオスの写真を撮ったので、多分そのメスではないだろうか。
November 29, 2014, when I was walking the forest leading to the grassland one small bird perched on a branch of a tree in front of me. This bird seems to be seedeater from the shape of the beak. It is a female because the color of the whole body is sober, but it is difficult to determine the species because female of any kind of seedeater is similar. I suppose this bird is the female of the Double-collared seedeater, because I took the photo of its male last time.

October 4, 2014, I went to Nyuwasu park (Parque Nu guazu) in the place of about 30 minutes by bus from Asuncion city center. There are many seedeater birds because there are wide meadows. I saw a bird smaller than a sparrow in the grassland. It seems the Sporophila of tanager family to see the first time in this park. Tanagers are often brightly colored. Males are typically more brightly colored than females. It is hard to distinguish female species because their color are more uniform and do not have special characteristics. This bird seems to be a female of the Double-collared seedeater.
