AVES COLUMBID/E. 



37 



"Each nest contained a single white egg. Either the variation in size 

 of the eggs of this species is very great, or else a few of the preceding 

 species were breeding with them ; for several eggs were found which were 

 very much larger than the others. I failed, however, to detect a single 

 specimen of C. picazuro among the birds which left the trees as we ap- 

 proached. This species was again met with at Carhue." (Barrows, Auk, 

 I, No. 4, p. 274, 75, July, 1884.) 



Of this pigeon as he saw it in Patagonia Mr. Hudson writes: 

 "This bird appears in winter in the settled parts of the Rio Negro; 

 they come in large flocks, and gather in great numbers on the ploughed 

 fields, eager to devour the wheat ; so that the farmers, when sowing broad- 

 cast, have to be constantly firing at them, or to keep trained dogs to chase 

 them from the fields. When on the ground, the flock keeps very much 

 crowded together, all the birds running with great rapidity, and eagerly 

 snatching up the grain or seed they find. The lively, brisk manner of 

 the Patagonian Pigeon is in strong contrast with the slow, stately steps 

 and deliberate manner of picking up its food of the Buenos-Ayrean 

 species (/. c, Colnmba picazitro: v. Scl. et Salv. P. Z. S., 1868, p. 143 

 — P. L. S.) ; but the voice of the former is exceedingly hoarse, while that 

 of the latter is the most agreeable dove-melody I have ever heard." 

 (Hudson, P. Z. S., 1872, p. 545.)
