109. Columba maculosa* (Temm.); Scl. et Salv. Nomencl. 
p. 132. 
Common to the north of Buenos Ayres ; but I have not 
observed it to the south of the city. Towards dusk large 
flocks wing their way to the marshes (I suppose, to drink) 
from the high ground. Immature birds want the fine grey 
and black transverse markings on the sides of the neck above 
the breast which are found in the adult., Common at Ba- 
radero in April. Legs red, between scarlet and carmine. 
110. Zenaida maculata (Vieill.) ; Scl. et Salv. P. Z. S. 
1868, p. 143. 
Very common, in the winter congregating in enormous 
flocks. Its chief food is the seed of the eardoon, which here 
covers the face of the country; and in June last year I took 
more than 700 seeds from the crop of a single bird. Com¬ 
mon at Baradero in April. Legs and feet dull scarlet, in¬ 
clining to carmine. 
111. Columbula picui (Temm.); Scl. et Salv. l.s.c. 
Very common, and found in gardens quite within the city. 
Partially gregarious in winter. 
112. Leptoptila chalchauchenia, Scl. et Salv. P. Z. S. 
1869, p. 633. 
Seen occasionally in the riverain wood, but not a common 
bird. Legs scarlet, with a tinge of crimson. 
113. Ballus nigricans (Vieill.); Scl. et Salv. Nomencl. 
p. 139. 
Pretty common in reed-beds, coming out to feed in the 
morning and about dusk. On the 13th October last I found 
a nest in a clump of thick reeds frequented by Limnornis cur - 
virostris and Synallaxis sulphur if era, in the riverain wood close 
to Belgrano. From the peculiar character of the nest I was 
careful to identify the owner, and, after having flushed the 
old bird once, retired some little distance to give it time to 
return. This it readily did; and on cautiously approaching and

this group usually sent from Buenos Ayres. C. maculosa occurs near 
Mendoza, and further south in Patagonia.—E dd.]
