The Ravin (spelled this way in the Bible) was the first bird Noah sent out to look for land but it did not return.
It was when he sent out the Dove that it came back with an olive leaf.

Crows and Ravins are highly intelligent birds.
In my lifetime, I've had the privilege of making friends with 7 different Crows.
Eventually they would return to the wild but I will never forget them and what they taught me.
