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.
Long-tailed Hermit
南米北部と中部アメリカに分布する大型のハチドリで、長い尾羽と白い眉斑が特徴的。熱帯雨林の薄暗い下層部に生息し、ヘリコニアの花を好む。
