Christian belief: The Bible recorded that the dove brought an olive branch to the ark as a message that the Great Flood had ended.
Following the Great Flood, Noah dispatched birds from the ark to see if the water had receded. First he sent a raven, but it found no place to rest and came back to the ark. Then he sent a dove, but the bird returned as well. Then, on the 301st day of the Great Flood, Noah sent the dove yet again. The dove stayed away all day, and then “the dove came in to him in the evening, and, lo, in her mouth was an olive leaf plucked off; and Noah knew that the waters were abated from off the earth.”
