The karavayka is a medium-sized bird from the ibis family. It has dark plumage with a bright green and purple metallic sheen, long legs, and a downward-curved beak.
The karavayka differs from other ibises in its almost entirely dark shiny plumage without white markings. It is important for nature because it eats many insects and indicates the condition of wetlands.
