Oriental Stork
Wetlands, flooded rice paddies, rivers, and marshes. Nests on tall trees, utility poles, and artificial platforms.
Song & Call Comparison

Oriental Stork
Essentially silent like all storks; produces loud mechanical bill-clattering at the nest as a greeting display. Chicks beg with hissing and squeaking. Rarely vocalizes otherwise.

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.
Oriental Stork
The oriental stork is one of the most endangered stork species, with fewer than 3,000 individuals remaining in the wild. It was once widespread across East Asia but declined dramatically due to wetland drainage and pesticide use. Reintroduction programs in Japan and Korea have achieved notable success.
