A dove returned to Noah with an olive leaf after the floodwaters receded. In Genesis 8, Noah first sent out a raven and later sent a dove to test whether the waters had fallen from the earth.
The dove initially returned because it found no place to rest. Noah waited seven days and sent it again; this time it came back with a freshly plucked olive leaf. After another seven days, the dove did not return, signaling that dry land was becoming available.
The olive branch later became a widely recognized symbol of peace and reconciliation. That broader symbol developed through many cultural and artistic traditions, while the biblical scene itself concerns finding evidence that the floodwaters were retreating.
The raven and dove are both part of the episode, but they have different roles. The bird carrying the olive leaf is specifically the dove, not the raven.
