flocks through the year. Many nests were found early in Novem- 

 ber, all placed in trees in dry woods, and only ten or fifteen feet 

 from the ground. 



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 approached. This 

 species was again met with at Carhu6. 



170. Zenaida maculata {VieilL). Faloma (Dove). — 

 Abundant everywhere in thinly wooded districts but not on the 

 bare pampas. At Concepcion it was abundant throughout the 

 year in small flocks, but I failed to discover its nest or eggs. 



171. Columbula picui {Temm.) Palomita (Little 

 Dove). — This tiny Dove was only met with in abundance in 

 wooded regions, but appears to be gradually spreading over the 

 pampas wherever man carries shrubs and trees. It nests fearless- 

 ly in the gardens at Concepcion, and even in the orange trees 

 which border the public square, laying always two white eggs. 

 I think two broods are often reared in a season, but not more. 

 Yet I found occupied nests from November 17, until April 13. 

 At the latter date many of the summer birds had gone north for 

 the winter and the nights were becoming frosty. I found the 

 nests most frequently, however, during January and February. 



172. Leptoptila chalcauchenia Scl. et Salv. Paloma 

 (Dove). — Only seen at Concepcion, where it is an abundant 

 resident. It is almost constantly on the ground, singly or in pairs, 

 never more than three or four together, and usually close to the 

 border of some stream or marsh. When alarmed it takes to the 

 thickets, but very soon seeks the ground, as if it could not endui"e 

 to perch longer. Yet the only nest I found was placed among 

 the matted branches of some bushes, about seven feet from the 

 ground. The two white eggs were more nearly spherical than 

 are eggs of any other Dove of my acquaintance. During flight 

 the species is easily recognized by the rufous under-wings. 



173. Penelope obscura Wagl. Pavo del Monte 

 (Wood Turkey). — Limited to the borders and islands of the 

 river, w^here in heav-y growths of timber it is not uncommon, 

 though rarely seen. It has a very harsh, cackling cry, and is said
