are generally two, sometimes three, in number. In a nest that 

 I once robbed of thi-ee eggs, on going to it again about a week 

 later, I was sm-prised to find two more laid, one of which was 

 a very light colom-ed one. * * * * j once had my cap 

 knocked off by this bii'd while taking its eggs, and had it not 

 been for a friendly piece of tussac gi'owing near, I should have 

 fallen into the sea from- the perpendicular cliff where the nest 

 was situated." 



The ii'is in this Caracara is dark brown, the cere, legs, and 

 feet are a bright lemon yellow, and the bare skin of the crop 

 is of the same colour, but paler and not so bright. In imma- 

 ture bii'ds the cere and feet are of a slaty colour. 



This species is well figured in Temminck's "Planches 

 Coloriees," plates 192 and 224 ; the first of these plates being 

 the figiu'e of the adult, and the second of the immature bird. 



The egg of this species is figui-ed in the "Ibis," vol. 2, 

 pi. 1, figure 1.*
