 University Museum have furnished bases for the descriptions here given. 



" Mr. Burgess found this bird breeding on the coast of the lower Arroyo 

 Grande, which flows into the Rio Negro from the north, some years ago. 

 The birds were in a small colony, and the nests were on big tussocks of 

 grass in a marshy place." (O. V. Alpin, on Birds Uruguay, Ibis, p. 199, 

 1894.) 



Mr. Barrows found the birds abundant on the lower Uruguay in 

 summer. Here he met with them in flocks, and they were very tame and 

 unsuspicious, allowing near approach to them while feeding. " During 

 clear, hot days they were often seen to rise in spirals to an immense height 

 and continue floating in circles for hours." (Barrows, Auk, I. 1884, p. 272.)
