Their beaks were orange-red; and over their bases grew crest-like protuberances, like the comb of a cock.

Their eyes had dark pupils and white irides, encircled by rings of a deep red colour; and, in short, the whole appearance of these beautiful creatures was such that, like the peacock, when once seen, they could never be forgotten.
"I have never seen one of them before," remarked Lucien, "but I have no difficulty in telling what they are." "What ?" inquired Basil and Francois, impatiently.
"_King-vultures_." As Lucien said this, the birds, that did not seem to regard the presence of the party, swooped suddenly down towards the carrion.

The boys followed them with their eyes--curious to witness what effect their arrival would have upon the buzzards and black vultures.

To the surprise of all, not one of the latter was now to be seen near the carcass! While the attention of the party had been directed to the king-vultures, the others had been regarding them as well; and, knowing from experience what these great birds were, both buzzards and black vultures had scattered precipitately, and now sat upon the rocks at a respectful distance! The king-vultures, without seeming to heed their presence, hopped up to the carrion, and commenced tearing it with their beaks.

In a few minutes these creatures, that had appeared so clean and beautiful--for the king-vultures are as proud of their plumage as peacocks, and usually keep it in the best order--exhibited a picture of filth that was disgusting to look upon.
