About These Birds
Barn Swallow
ツバメは世界で最も広く分布するツバメ科の種で、スズメ目の中でも最長の渡りを行うもののひとつ。北半球全体にわたってその到来が春の訪れを告げ、古代ギリシャから現代の詩に至るまで文化的な言及を生んできた。ツバメは営巣にほぼ完全に人工構造物を利用するようになっている。
Rock Pigeon
The rock pigeon is the ancestor of all domestic pigeon breeds and one of the most abundant birds in cities worldwide. Pigeons have served humans as messengers, food, and subjects for scientific research — their homing ability and vision have been studied extensively. Darwin's study of pigeon breeding contributed to his theory of evolution.
