Iris brown. 
This beautiful red-crested Woodpecker is found over a great 
stretch of country, as I observed them commonly in all parts of the 
province of Catamarca, as well as in the sierras of Cordoba; and I 
believe they are occasionally met with as far south as Buenos 
Aires. 
" They fly in pairs, frequenting old trees ; and their note is exceedingly 
shrill.

Tris light blue. 
These noisy birds, abundant in various parts of Misiones as well as 
the rest of the north of the Republic, go about in flocks of eight or 
ten and settle on the same tree, which they proceed to ascend very 
comically in a spiral or corkscrew fashion, each head touching the 
preceding tail. They are not seen in dense forests, but only out in 
the open, on some old, usually dead tree; and I think I observed 
them as far south as the sierras of Cordoba.

Iris dark red. 
Very common inhabitants of the open campo, where they are 
usually discovered, either on the ground, or more generally perched 
on an ant-hill, two feet high, and constructed of such intensely 
hard ferruginous clay as to admit of almost indefinite weight on the 
top without disturbing its shape; the tops of these they are 
engaged in pecking. They very rarely take to a tree, and are never 
observed in the woods. They fly in pairs ; but commonly a good 
many pairs remain within call of each other.

Iris brown. 
These birds are very rare here, and have a peculiar ery, which it is 
impossible to describe otherwise than by saying that it resembles the 
voice of a ventriloquist, very deceiving as to distance, and extremely 
mournful. They frequent the topmost branches of the loftiest 
forest-trees, and are very difficult to discover, as they sit motionless. 
A Monte-Cristo rifle had not sufficient range to reach them. One 
I shot on the banks of the Vermejo had some small fish-scales in its 
crop.
