They are found in New Zealand.
They live on fast flowing rivers.
They are about 20 inches long and slate blue, which helps them blend into their river habitat. They have a special thick edge to their lower bill for scraping insect larvae off rocks to eat.
They are great swimmers, even in the strong currents of rivers. They are active in the early morning and late evening, feeding and defending their habitat from other ducks. They are preyed on by weasels (stoats), dogs and cats, which were introduced to New Zealand.
They eat the early stages of water insects (larvae).
: Females lay between 4- 9 eggs. She keeps them warm (incubates) them until they hatch in a little over a month.
