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.
European Goldfinch
The European goldfinch is a strikingly beautiful finch whose tinkling song and colorful plumage have made it popular in art and as a caged bird for centuries. It appears frequently in Renaissance paintings as a symbol of the Passion of Christ. Flocks of goldfinches are charmingly called a charm.
