'Birds' in the Bible

Look at the birds of the heaven, that they sow not, nor reap, nor gather into granaries, and your heavenly Father nourishes them. Are ye not much more excellent than they?

And Jesus says to him, The foxes have holes, and the birds of the heaven roosting-places; but the Son of man has not where he may lay his head.

and as he sowed, some grains fell along the way, and the birds came and devoured them;

which is less indeed than all seeds, but when it is grown is greater than herbs, and becomes a tree, so that the birds of heaven come and roost in its branches.
