The white birds appear as points of light in the river until they can be heard
They obey parliamentary procedures for the most part until ordinary words are not enough
Then they either
Across the vault of the sky lights rise and fall, signaling splendor
Morning and evening
And it was so.
Genesis 1:20 NIV
 And God said, “Let the water teem with living creatures, and let birds fly above the earth across the vault of the sky.”
