Barrows o?i Birds of the I^oiver Uruguay. 
[July 
year had been spent at Conception that I found this species 
there. Possibly it had been overlooked, as all the specimens 
subsequently taken near this place were found in cultivated 
ground, sevefal being shot while perched on sheaves of wheat 
and in full song. This was at Christmas time, 1880. Two 
months later we found it abundant in similar places near Bahia 
Blanca, as well as on the grassy slopes at the foot of the Sierra 
de la Ventana. At all these places it was breeding, but nothing 
was learned of its nest or eggs. 
34. Embernagra platensis ( Gm .). — A common resident at 
Concepcion, where it breeds. Also numerous in suitable locali- 
ties at all other points visited. It prefers damp ground with or 
without bushes, and where the plumed pampas-grass abounds 
the bird delights to sit swaying on its feathery tips, chanting his 
weak but well-meaning song. The nest is placed near or on the 
ground and contains three white eggs with a very few dark flecks 
at their larger ends. Sets were taken at Concepcion, October 
12 and December 7, and at Azul, January 28, indicating a second 
and perhaps a third brood. 
35. Chrysomitris barbata {Mol.). Jilguero (Gold- 
finch). — I first made the acquaintance of this sprightly little 
songster in the markets and bird-stores of Buenos Aires where 
they are kept by hundreds as cage-birds. Afterwards I found 
them more or less abundant at all points visited. Like our 
common Yellowbirds, they are almost always in flocks, always 
restless, and able to sing well when they feel like it. Nothing 
was learned of their nesting habits. 
36. Sycalis luteola ( Sparm.) . Misto or Mixto. (Mixed, 
perhaps in allusion to the character of the flocks.). — Abundant 
everywhere in immense flocks, often of many thousand individ- 
uals, and largest in winter, when they are shot by the hundred 
and sold in the markets of Buenos Aires. Other species often 
help to sw~ell the size of these flocks, Chrysomitris perhaps 
most often, and then Zonotrichia. Sp e rm of) h if a , and even An- 
thus correndera. Nests were found during November, Decem- 
ber, and January, and probably many breed during October. 
The nest is very variable in size, material and location. Probably 
it is oftenest placed on the ground, but I have taken eggs from 
a well-built nest of the Oven Bird {Furnarius) ten feet from 
the ground, and was told by natives that the bird often nests in
