238 A 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 ventand 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 colour, and often six or eight are found in the same 
nest. It feeds upon the smaller quadrupeds, lizards, &e.
