After the dove returned with an olive leaf, Noah sent a dove from the Ark again.
Genesis 8 describes Noah testing whether the Flood waters had receded. He first sent a raven, which went back and forth. He then sent a dove, which initially found no resting place and returned to him. After waiting seven days, Noah sent the dove again; it came back carrying a freshly plucked olive leaf.
Noah waited another seven days before sending the dove a third time. On that occasion, it did not return, indicating that the waters had diminished enough for the bird to remain outside. The sequence is therefore more detailed than the familiar image of a single dove flight.
The olive leaf became a widely recognized symbol of peace and restored land, although Genesis itself presents it primarily as evidence that the waters were falling. This question is distinct from asking which bird Noah sent first: the raven appears earlier, while the bird associated with the olive leaf is the dove.
