Juvenile - Paler than adult, with a white breast, and lacks the facial shield; the adult's black plumage develops when about 3-4 months old, but the white shield is only fully developed at about one year old.

Similar Species

Similar to the Eurasian Coot (F. atra) which lacks the red knobs. The knobs may not always be obvious in the field. Note that the black feathering between the shield and the bill is more rounded in Red-knobbed Coot. In Eurasian Coot the bill feathering comes to an acute angled point at the side of the bill.

Distribution

Sub-Saharan Africa including Madagascar, and disjunct in Morocco and southernmost Spain.

Taxonomy

This is a monotypic species[1].

Diet

Mainly eats plant material, supplemented with molluscs, crustaceans and insects; occasionally the eggs of other water birds.

Vocalisation
