Circus cinereus, Vieill. Nublina is the name for the adult male, and 



Barril for the female and young. 



" This species is less rapid in its motions than the other hawks, 

 and generally flies nearer the ground. It feeds chiefly on rats and 

 mice. The ruflf of feathers round the head gives it the appearance 

 of an owl. Iris bright yellow." 



Elanus dispar. Baylarin. 



" This is the rarest of the Chilian hawks. It hovers over its prey, 

 and from that it takes its name, which signifies dancer. Eyes large ; 

 iris yellow. Found in pairs. It appears to be migratory, making 

 its appearance during the winter." 



Athene cunicularia, Mol., Hist, de Chile, pp. 293 and 390. Piqueu. 

 " This species lives in holes in the ground, which it makes to a con- 

 siderable depth. In the afternoon it comes out of its cave and basks 

 in the sun. It appears to live in communities, as several inhabit the 

 same cave. Iris bright yellow." 



Athene ferox, Vieill. Chucho. 



" This is the smallest species of owl found in Chile ; it is very 

 destructive to pigeons, killing the young and eating only the brains of 

 its victims. It is much dreaded by small birds, and the hiding-place 

 of the Chucho is frequently discovered by their cries. It makes its 

 nest in holes of trees. Iris yellow."

Caprimulgus bifasciatus, Gould. Plasta and Gallina ciega. 



** This bird is found in bushy places on the east and west side of 

 the Andes. Iris brown. The female is rarer than the male. It is 

 called Plasta from its laying flat on the ground : Gallina ciega in 

 Spanish signifies BHnd-hen." 

 Hirundo leucopygia, Licht. Golondrina.

 which is composed of grass and feathers, in holes under the tiles of 

 houses. Remains in Chile throughout the year." 

 Ceryle torquata, Gmel. Martin Pescador. 



" The Indian name of this bird is Quete Quete. It inhabits all the 

 southern provinces of Chile, and may be generally seen sitting on a
