shells: or else, if it is too young to be able to do so, it will
gradually encircle the egg with its coils, and hold it so tight as
to break it at the end, just, in fact, as though a piece had been
cut out with a knife; then holding the remaining part in its
folds, it will suck the contents. In the same manner, too,
when it has swallowed a bird whole, it will make a violent effort,
and vomit the feathers.
