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.
Black-tailed Trainbearer
A spectacular hummingbird (10 cm body + 15 cm tail in males) found in Andean highlands from Colombia to Peru at 2,500-4,000 m. Males have extraordinarily long, black outer tail streamers. Nectarivore of páramo and cloud forest edges. Named for its dramatic trailing tail feathers.
