'Birds' in the Bible

I beheld, and, lo, there was no man, and all the birds of the heavens were fled.

As a cage is full of birds, so are their houses full of deceit: therefore they are become great, and waxen rich.

How long shall the land mourn, and the herbs of every field wither, for the wickedness of them that dwell therein? the beasts are consumed, and the birds; because they said, He shall not see our last end.

Mine heritage is unto me as a speckled bird, the birds round about are against her; come ye, assemble all the beasts of the field, come to devour.
