36 Mr. E. Gibson on the Ornitholoyy of 
where the head and neck of a watchful Maguari Stork (Cico-_ 
mia maguari), towering above the hunco, betrayed that it 
was standing up on its nest, while the many-coloured little 
Cyanotis azare crept up and down the green rushes in close 
proximity to me, and a hundred different sounds and cries 
spoke of nearly as many different species of waterfowl present, 
and kept me busy making mental memoranda. But the out- 
line of the sketch is quite sufficient, without all the fasci- 
nating accessories. 
I have seen the female conveying the young on its back, 
and on one such occasion managed to press the bird so close 
that I captured one of the young in down. Though only a 
few days old, it gave me a great deal of trouble to catch it, 
diving always just as the horse’s nose almost touched it; and, 
but that the water was so clear that I could see and follow 
its motions and so tire it out, it would have proved too 
quick for me. It had no sign of the black head and neck, of 
course, being in down; the colour was pure white, with a 
black beak. 
The general clutch of eggs is either three or five. I only 
once ever met with a nest containing six. They are of a 
smooth glossy cream-colour; and the average measure- 
ment of a large series is 333 x 272, varying from 4% x 244 
to 828 x 248. 
38. Cyanus coscoroBa. Native name “‘ Ganso,” or Goose. 
Common, but not nearly in such large numbers as the last, 
though in the month of August I have seen flocks of from 
eleven to seventeen. As a rule it is to be found in pairs. 
The occurrence of flocks in the above-mentioned month seems 
strange; for it is generally breeding then, and, though affecting 
certain favourite localities, does not nest in colonies. It does 
not associate with C. nigricollis, though, of course, it 1s often 
found in the same Jagoons. Even more wary than the latter, 
it is also more shy, and usually takes flight when alarmed. The 
note is a loud trumpet-call, uttered both when flying and on 
the water, if its suspicions should be aroused. In the latter 
case the male and female answer each other alternately with
