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。
Red-crowned Crane
The red-crowned crane is one of the rarest crane species and a potent symbol of longevity and fidelity in East Asian culture. Their elaborate unison call and dancing displays have inspired art and folklore for millennia. The resident population on Hokkaido, Japan, recovered from about 33 birds in 1952 to over 1,800 today.
