Song & Call Comparison

Male produces a complex, scratchy song with buzzy 'dzzzzt' notes. Gives a nasal 'chee-chee-chee'. Males sing year-round, even in winter; one of few hummingbirds with true song.

Largely silent; produces mechanical bill-clattering 'clap-clap-clap' when greeting at the nest — similar to White Stork. Also gives low croaking grunts. Rarely calls in the wild.

Massive shoe-shaped bill, one of the largest of any bird — pale yellowish-grey with darker markings
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.
Shoebill
The shoebill is one of the most sought-after birds for birdwatchers visiting Africa, prized for its prehistoric appearance and massive bill. It can stand motionless for hours before collapsing forward to seize prey in its enormous bill. Despite standing over a meter tall, shoebills weigh relatively little due to their hollow bones.
