In Genesis, the first bird Noah sent from the Ark was a raven. Genesis 8:7 says Noah sent it out after the Ark came to rest and the waters began to recede.
The raven is followed by a series of dove flights. The dove is sent to discover whether the waters have diminished from the ground, and later returns with an olive leaf. Because the dove receives more narrative attention, readers sometimes remember it as the first bird, but Genesis names the raven first.
The two birds have different roles in the sequence. Genesis says the raven went to and fro until the waters dried from the earth, while the dove’s returns provide more specific signs about the condition of the land. This question concerns the first bird, not the bird that brought the olive leaf.
