partiality for human excrement ; but, should there not be a sufficient supply of garbage, it will 

 feed on lizards, snakes, frogs, insects of various kinds, worms, and slugs. Its flight is tolerably 

 easy, though slow ; and at a distance, on the wing, it reminds one much of a Raven. It walks 

 leisurely, with ease, lifting its feet rather high as it stalks along ; and it can even run with 

 tolerable facility. When wounded it vomits up the horrible filth on which it has been feeding ; 

 and when irritated it will utter a harsh croak, which is the only sound I have heard it emit. It 

 lives quite contentedly in confinement ; and Lord Lilford informs me that those he has kept were 

 always very quiet and peaceably disposed towards other raptorial birds in the same division of 

 his aviary. 



The specimens figured are the adult and young birds above described. 



In the preparation of the above article I have examined the following specimens: —
