Of all the carrion-feeders it is generally the last which leaves the skeleton of a dead animal, and may often be seen within the ribs of a cow or horse, like a bird in a cage.

Another species is the Polyborus Novae Zelandiae, which is exceedingly common in the Falkland Islands.

These birds in many respects resemble in their habits the Carranchas.

They live on the flesh of dead animals and on marine productions; and on the Ramirez rocks their whole sustenance must depend on the sea.

They are extraordinarily tame and fearless, and haunt the neighbourhood of houses for offal.
