King River. 1916, January 3rd. Fairly numerous on a 
Shallow, grass-grown, weedy swamp, about six miles from 
the river. Several birds were breeding; they leave the 
nest, by diving and swimming under water for some dis- 
tance; and return in a similar manner, coming up right 
alongside of the nest, 
Male, shot from the nest, An oval space (3 x 2 in. )on 
the breast and abdomen was quite bare of feathers, the 
skin round the edge being produced into a flap about a 
quarter of an inch long; a cellular membrane under the 
bare skin being impregnated with a watery fluid. 
i have frequently noted a similar condition in. nesting 
females of various species,
