The word "chionis" is spelled k-eye-oh-n-i-s, with the stress on the second syllable. It is a genus of bird in the family Chionidae, commonly known as sheathbills. These birds have white plumage and are known for their habit of eating the feces of other birds.

Chionis is a genus of flightless birds belonging to the family Chionidae. There are two species within this genus, the Snowy Sheathbill (Chionis albus) and the Black-faced Sheathbill (Chionis minor), both of which are native to the Antarctic region.
The Snowy Sheathbill is a medium-sized bird that measures approximately 40 centimeters in length. It has a distinctive white plumage with a small, curved bill and pink legs. In contrast, the Black-faced Sheathbill is slightly smaller and has a black mask-like pattern on its face, with white plumage covering the rest of its body.
These birds are known for their unique feeding habits, as they scavenge on carrion and prey on small invertebrates. They have a specialized bill that allows them to tear open the flesh of dead animals, and they also use their bills to probe the soil for insects and other arthropods.
Chionis birds are highly adapted to the harsh Antarctic environment. They have thick plumage and a layer of fat to provide insulation against the extreme cold. They are also capable of surviving long periods without food, relying on their fat reserves to sustain them.
Due to their restricted habitat and specialized adaptations, Chionis birds have a limited range and population size. They are considered to be vulnerable to environmental changes, particularly those resulting from climate change and human activities. Efforts are being made to monitor and conserve these unique birds and their fragile ecosystem.
