Most of the vultures, instead of attacking the carrion, were, as we have already seen, sitting perched upon rocks and trees--some of them in listless attitudes, as though they were not hungry, and did not care to eat.
Basil proffered an explanation.
"No doubt," said he, "they are waiting until the flesh becomes putrid.
It is said that they prefer it in that state." "And that," remarked Lucien, "is another assertion that has no foundation in fact.

They do _not_ prefer it in that state.

On the contrary, it is certain that vultures like their food better when fresh, and eat it so when they can get it." "And what hinders them now ?" inquired Francois.
"The tough hide hinders them.

These birds do not possess the great muscular power in their claws that eagles do, else you would soon see the big-horn reduced to a skeleton.

They are waiting until its skin becomes more tender, through decomposition, so that they may be able to tear it open.
