About These Birds
Anna's Hummingbird
Anna's hummingbird is the most common hummingbird along the Pacific coast and one of only three species resident in the United States year-round. Males perform spectacular dive displays, plummeting from 40 meters and pulling up with a loud chirp produced by tail feathers. Their body temperature can drop to near ambient at night to conserve energy.
Minute Hermit
ブラジル東部の大西洋岸森林に生息する小型のハチドリで、Idaliaハーミットとも呼ばれる。生息地の破壊により個体数が減少しており、保護が必要とされる。
