ニュワス公園に住むフタスジヒメウソのつがいかな？ (Are they a pair of Double-collared seedeater?)
- 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.

もう一羽は全身が薄いこげ茶色の地味な色なのでメスだ。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。
Another one is a female because the color of the whole body is sober 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.

ニュワス公園に住むフタスジヒメウソのメス (Female of Double-collared seedeater living in Ñu Guazú Park)
メスの羽毛は薄いこげ茶色であり、翼は濃く腹部は薄く地味である。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。
The color of the whole body of female is sober with light dark brown plumage, thick of wings and thin of belly.
The plumages of the male and female are so different that it is hard to identify them as the same species.
