What does a bird symbolize?

Sunrise, captured at its predictable time — it was 5:19 — with the sudden appearance of a bird. Seeing it only now, as I process this morning's photographs, I wonder what does a bird symbolize?

The internet answers most simplistically: Freedom!

Which cues "Ballad in Plain D"...

Ah, my friends from the prison, they ask unto me
“How good, how good does it feel to be free?”
And I answer them most mysteriously
“Are birds free from the chains of the skyway?

ADDED: I have made a study of the birds of the Bible, and I have produced a list of 8 quotations, which I've ranked in the order that seemed right to me:

8. Matthew 8:20 — "Jesus replied, 'Foxes have dens and birds have nests, but the Son of Man has no place to lay his head.'"

7. Ezekiel 38:20 — "The fish in the sea, the birds in the sky, the beasts of the field, every creature that moves along the ground, and all the people on the face of the earth will tremble at my presence. The mountains will be overturned, the cliffs will crumble and every wall will fall to the ground."

6. Psalm 50:11 — "I know every bird in the mountains, and the insects in the fields are mine."

5. Ecclesiastes 9:12 — "Moreover, no one knows when their hour will come: As fish are caught in a cruel net, or birds are taken in a snare, so people are trapped by evil times that fall unexpectedly upon them."

4. Job 12:7-8 — "But ask the animals, and they will teach you, or the birds in the sky, and they will tell you; or speak to the earth, and it will teach you, or let the fish in the sea inform you."

3. Psalm 102:7  — "I am like a desert owl, like an owl among the ruins. I lie awake; I have become like a bird alone on a roof. All day long my enemies taunt me; those who rail against me use my name as a curse."

2. Matthew 6:26 — "Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they?"

1. Job 41:1-5 —"Can you pull in Leviathan with a fishhook or tie down its tongue with a rope? Can you put a cord through its nose or pierce its jaw with a hook? Will it keep begging you for mercy? Will it speak to you with gentle words? Will it make an agreement with you for you to take it as your slave for life? Can you make a pet of it like a bird or put it on a leash for the young women in your house?"

"The devil has two strategies: the seduction of worldly promises... self-realization, careerism, and worldly success...."

"... and when this fails... there is humiliation, there is rage.... His pride is so great that he enjoys destroying with rage.... May the Lord give us the grace to be able to recognize that spirit that wants to destroy us with fury and when that same spirit wants to console us with worldly appearances, with vanity.... May the Lord give us the grace to discern the path of the Lord, which is the cross, from the path of the world, which is vanity, appearances, window-dressing."

Said the Pope, in Rome, where the coronavirus rages, though this homily seems to speak to people who are enjoying good times — self-realization, careerism, worldly success, vanity, appearances, window-dressing. But that gives it special effect: Those things you used to enjoy were never good for you, and if you are forced to relinquish them, well, you ought to have given them up on your own.

I don't know if the Pope connected these thoughts to the coronavirus, but I note that the word "quarantine" originally referred to the 40 days Jesus spent in the desert tempted by the devil. There was a temptation to worldly success:

Again, the devil took him to a very high mountain and showed him all the kingdoms of the world and their splendor. “All this I will give you,” he said, “if you will bow down and worship me.”

So, when you are in your quarantine, you may long for all the vanity, appearances, window-dressing you have given up. The response from Jesus was:

"Away from me, Satan! For it is written: ‘Worship the Lord your God, and serve him only.'"
