of Aconcagua in the North down to Chlloe ; but is commonest in the neighbourhood of the 

 city of Vaklivia. In Southern Chili it keeps to the edges of the forests. In the central 

 provinces it is foimd on the lower outlyers of the Cordilleras, and among the bushy woods 

 intermixed with larger trees, often approaching the settlements in pursuit of small birds, 

 pigeons, and fowls. It is fond of selecting the lofty summit of a dead tree as a resting-place, 

 and descends thence quickly on its victim, carrying it off. to a quiet place to be devoured. 

 Females of this species were twice shot by Messrs. Philippi and Landbeck near Valdivia in the 

 act of robbing the hen-roosts. 



The nidification of A. chilensis is said to resemble that of the European A. nisus^ but 

 Messrs. Philippi and Landbeck have not yet succeeded in obtaining specimens of the eggs. 



Our figures of this bird are taken from specimens now in the British Museum, which 

 were formerly in the Zoological Society's Museum, and were collected by Captain King in the 

 Straits of Magellan. The front figure is reduced to two-thirds of the natural size.
