Black-Chinned Sparrow

ブラックチンスパローは北アメリカ南西部に住むホオジロ科に属する鳥です。 The Black-chinned Sparrow lives in the southwest United States to Mexico.

私たちはラッキーなことにオスの繁殖期の写真を撮る事ができました。繁殖期にはこの様に黒いアゴになるそうです。それ以外の時はメスと同じように黒い色がなくなります。We were lucky that we could capture the male bird clearly showing black color on his chin. The male shows the black chin during the breeding season only. They look very much like female birds without the black chin outside of breeding season.
