'Birds of the Air' in the Bible

likewise of the birds of the air seven of every kind, male and female to save seed upon all the earth.

And Rizpah the daughter of Aiah took sackcloth and spread it under her upon the rock, even from the beginning of harvest until rain dropped upon them out of heaven, and suffered neither the birds of the air to fall on them by day nor beasts of the field by night.

I looked about me, and there was nobody, and all the birds of the air were away.
