238 4 Description of the Birds 



Young. — Head and neck rufous tawny, with indistinct longi- 

 tudinal black streaks ; back and shoulders light rufous, with 

 large irregular or triangular black spots ; chin nearly white ; 

 throat light tawny rufous, with irregular streaks like those on 

 the head ; belly with the same ground color as breast, and 

 streaked or spotted in front, but behind like the vent and thighs, 

 without variegations; wing feathers all distinctly tipt with 

 white, with the black tinge stronger, and the yellow of the 

 feet, toes, and cere is less clear. 



This hawk occurs very frequently in all parts of the colony, 

 as well as in the country both to the eastward and northward 

 of it. When in search of its prey it is generally seen soaring 

 about in open country, but when disposed to rest it retreats 

 towards mountains or rocky knowls, and there passes the 

 night. In such situations, also, it constructs its nest, which 

 it forms externally with dried twigs, and internally with hair 

 and feathers : according to Le Vaillant, the eggs are of a 

 rufous color, and often six or eight are found in the same 

 nest. It feeds upon the smaller quadrupeds, lizards, &c.
