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.
Eurasian Eagle-Owl
The Eurasian eagle-owl is one of the largest owl species in the world, with females sometimes reaching a wingspan of nearly two meters. Its deep booming call can be heard up to four kilometers away on calm nights. These apex predators sit at the top of the avian food chain, preying on other raptors including buzzards and smaller owls.
