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。
Demoiselle Crane
The demoiselle crane is the smallest crane species but undertakes one of the most grueling migrations, crossing the Himalayas at altitudes over 8,000 meters to reach wintering grounds in India. Named for its elegant appearance by Marie Antoinette, it is the second most abundant crane species in the world.
