a kind of natural pouch or hollow for that purpose, situated 

 below each wing); when the parent-bird dived the young one 

 separated itself and remained afloat. The cry of the adult 

 resembled that of the Peacock, though naturally not so 

 powerful, whilst the young had but a feeble note. Under 

 the title of " nestling," I have described the bare parts of 

 the chick. When placed upon- the ground (while it bit me 

 savagely), it sat with its head and neck erect, the body 

 resting on the ground, and the feet stretched out behind ; 

 these it used for progression, propelling itself along with 

 them in a succession of frog-like jumps. 



In my former paj)er I described three nests, all taken 

 very early in the season, namely, the last week of August 

 (1877); these, I recollect, were all situated in the same 

 locality, in the deep and central part of a swamp ; were 

 built of wet water-weeds (which the sitting-bird hurriedly 

 drew over the eggs on leaving the nest at my approacli), 

 and contained two clutches of three and one of two eggs 

 respectively. There is no further entry in my diary until 

 1898, when I chronicled four nests between 14th and 20th of 

 December; these in position and materials were very similar 

 to the previous lot ; Avere again in two groups of two each, 

 while the sitting-birds (one of which was a male) showed the 

 same solicitude in covering-up the eggs. Of the clutches, all 

 much-incubated, two this time were of four eggs, the other 

 two of three respectively. Since the last-named year, I 

 have met Avith no further nests ; but I would premise that 

 they are difficult of approach in a canoe, owing to the 

 density of " durasnillos^'' and ^'juncos," and equally awkward 

 on horseback for the same reason, in addition to the deep 

 and muddy nature of the position selected. 



The eggs average 5G x 37 mm.
