After the waters receded, Noah sent a raven through the Ark’s opening.
Genesis 8:7 says Noah sent out a raven after the Ark had come to rest and the waters had diminished. The raven went back and forth until the waters dried from the earth. Noah then sent a dove on separate occasions to test whether the ground was clear.
This question is distinct from the famous olive-leaf episode. The dove returned with a freshly plucked olive leaf, providing the narrative’s recognizable sign that the waters had fallen. The raven is the first bird named in the sequence, while the dove’s later flights receive more detail.
The text does not say that the raven returned to Noah carrying anything. It simply describes the bird moving back and forth. That is why “a raven” is the precise answer, whereas the dove is associated with the olive leaf and later with not returning after its final release.
