'Birds' in the Bible

Consider the birds of the sky, that they do not sow or reap or gather [produce] into barns, and your heavenly Father feeds them. Are you not worth more than they [are]?

And Jesus said to him, "Foxes have dens and birds of the sky [have] nests, but the Son of Man has no place to lay his head."

and while he was sowing, {some seed} fell on the side of the path, and the birds came [and] devoured it.

{It} is the smallest of all the seeds, but when it is grown it is larger than the garden herbs and becomes a tree, so that the birds of the sky come and nest in its branches."
