"Castanet" Natural Recordings by Native Speakers
A castanet is a small, hollow resonator, typically made of wood or metal, that is clicked together to produce a sharp, percussive sound, often used in music, particularly in flamenco and classical music.
A cassowary is a large, flightless bird native to Australia and New Guinea. It has a distinctive casque, or crest, on its head, and is known for its aggressive behavior if it feels threatened or cornered. Cassowaries are closely related to emus and kiwis, and are considered to be one of the most primitive and ancient bird species still in existence.
