Do you know when mountain goats are born? Have you watched wild deer give birth?
Do you know how long they carry their young? Do you know the time for their birth?
Do you know when they will crouch down and bring their young into the world?
In the wilds their young grow strong; they go away and don't come back.

How fast the wings of an ostrich beat! But no ostrich can fly like a stork.
The ostrich leaves her eggs on the ground for the heat in the soil to warm them.
She is unaware that a foot may crush them or a wild animal break them.

It was I who made her foolish and did not give her wisdom.
But when she begins to run, she can laugh at any horse and rider.

Does a hawk learn from you how to fly when it spreads its wings toward the south?
Does an eagle wait for your command to build its nest high in the mountains?
It makes its home on the highest rocks and makes the sharp peaks its fortress.
From there it watches near and far for something to kill and eat.
Around dead bodies the eagles gather, 1 and the young eagles drink the blood.
