About These Birds
Emu
에뮤는 두 번째로 키가 큰 현존 조류이자 호주 최대 조류이다. 날지 못하지만 시속 50km로 달릴 수 있으며 강한 다리로 포식자를 방어한다. 수컷이 알을 품고 새끼를 기른다.
Ruby-throated Hummingbird
The ruby-throated hummingbird is the only breeding hummingbird in eastern North America. These tiny birds beat their wings about 53 times per second and can fly backwards, sideways, and even briefly upside down. They make an extraordinary non-stop 800 km crossing of the Gulf of Mexico during migration.
