the country. It sometimes soars to a great height. Its principal 

 food is partridges and domestic fowls. The young appear to accom- 

 pany the old for at least six months, and depend on them till that 

 age for food. I have frequently seen an eagle catch a patridge and 

 carry it to its young that would be waiting on a tree or rock ready 

 to receive it. Iris light brown; legs pale yellow; cere yellow. 

 Builds its nest on the tops of trees, and lays from three to four dirty- 

 white eggs." 

 Polyborus Brasiliensis, Sw. Traro and Tare. 



" Feeds on carrion, worms, frogs and the larva of insects. It is 

 common to see these birds following the ploughman, picking up 

 worms, &c. in the newly broken soil. They build their nests in 

 trees : the nest is composed of sticks and stems of a species of Ru- 

 mex, and on the outside is a kind of platform where the male sits 

 during the setting of the hen. The eggs are dirty white spotted 

 with brown. Iris brown ; legs and cere yellow. When pressed by 

 hunger it attacks chickens." 

 Phalocoboenus montanus, D'Orb. Tuique de la Cordelliera. 



" This is a very rare bird, occurring only in the valleys of the 



Andes at an elevation of from 5000 to 8000 feet. Found in pairs. 



Iris dark brown." 



Milvago pezoporos, Meyen. Thiique. 



" Common in all parts of Chile. Habits the same as the Traro 



{Pol. Brasiliensis). Iris brown ; legs light brown or grey." 



Buteo erythronotus. King. Aguilucha. 



*' This is the small eagle of Chile, as its name in Spanish implies. 



It inhabits the open parts of the country, and is mostly seen perched 



on the top of a solitary tree enjoying the sun in the afternoon. Base 



of the bill, cere and legs greenish yellow ; iris brown. Food, rats 



and small birds." 



Astur unicinctus, Temm., PI. Col. 313. Peuco. 



** This species of hawk is found in the retired and woody parts of 



the country : it appears to seek the shade during the day and hunts 



its food in the evening. Iris light brown." 



Falco anatum, Bonap. Gavilan. 



" The Gavilan is a rare bird in Chile, and the most rapid on the 

 wing of all the Chilian hawks. It is occasionally seen in open parts 

 of the country perched on a rock-stone. Iris brown; legs and nos- 

 trils yellow." 



Falco femoralis, Temm. Alcon. 



*' This is the species of hawk in Chile used for hunting partridges. 

 It is easily domesticated. I have seen them caught in a net for the 

 purpose of hawking, and in fifteen days afterwards follow their master 

 and hunt partridges when sprung by the dogs. Base of the bill and 

 margins of the eyes bright yellow ; iris dark brown." 



Tinnunculus Sparverius. Sarnicula. 



" This is the smallest of the hawk tribe in Chile. It is said to 

 build its nest in holes of trees. The female is easily distinguished 

 from the male by the bands across the tail-feathers. Iris dark brown.**
