Irides white; bill black ; legs and toes ochre-yellow, with 
black spots on some of the joints. 
The November bird is in perfect plumage and the August 
example is shewing signs of considerable wear. The April 
bird is in almost full plumage, still moulting on the body; 
the old feathers shewing no signs of eclipse plumage.

This is the most uncertain of all Ducks in the Ajo district, 
considerable numbers being often seen where for weeks 
hardly one can be flushed. It has a strong flight and is 
always rather wary, and has a loud hoarse “quack.” It 
breeds here, but I have only taken two sets of eggs, and 
both of these were in the nests of Fulica and contained the 
eggs of that bird also ; the natives say this is the usual 
custom of the bird, and assert that the Coot brings off the 
young. 
Sixteen eggs were brought home, and these measure: axis 
2’29 to 2’5 mm., diam. 1*72 to 1*75.
