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.
Gorgeted Sunangel
O beija-flor-anjo-de-coleira é um pequeno beija-flor das florestas nubladas andinas do sudoeste da Colômbia e noroeste do Equador. O macho apresenta partes superiores verde-brilhante e uma chamativa banda peitoral iridescente. Alimenta-se do néctar de flores nas florestas nubladas e matos da floresta andina. A fêmea é mais apagada. A desflorestação na sua área de distribuição restrita é uma preocupação para a conservação.
