Which is the only bird which hunt by sense of smell?

The Kiwi bird is the only bird which hunts by sense of smell. Kiwis are flightless birds native to New Zealand. They have long, thin beaks and nostrils at the tip of their beaks, which they use to sniff out insects and worms in the soil. Kiwis have a keen sense of smell, and they can even smell prey that is buried underground.
