'Birds of the Air' in the Bible

Look at the birds of the air; they neither sow [seed] nor reap [the harvest] nor gather [the crops] into barns, and yet your heavenly Father keeps feeding them. Are you not worth much more than they?

Jesus replied to him, “Foxes have holes and the birds of the air have nests, but the Son of Man has nowhere to lay His head.”

and of all the seeds [planted in the region] it is the smallest, but when it has grown it is the largest of the garden herbs and becomes a tree, so that the birds of the air find shelter in its branches.”
