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。
Great Blue Heron
The great blue heron is the largest heron in North America, standing up to 1.4 meters tall. These patient hunters can stand motionless for extended periods before striking at prey with remarkable speed. They nest in large colonies called heronries, often returning to the same site year after year.
