Details
The Campbell Islands Teal (Anas nesiotis) is a medium-sized swimming bird belonging to the family Anatidae.
Kan Island ducks are timid and mainly nocturnal, gathering in small flocks with couples or families, never in large flocks. Male and female ducks pair up all year round. They defend their territory during the breeding season. It mainly feeds on roots, grass seeds, leaves, grass fruits, rice, etc. in marshes and lake areas, and also eats invertebrates and arthropods.

The bowl-shaped grass nest of the nest is hidden far below the nearby water grass. Female ducks usually lay six eggs. During this time the duck is very active at night. They feed among riverbank vegetation.
