According to Genesis, a dove returned to Noah with a freshly plucked olive leaf.
Genesis 8:8–11 describes Noah sending out a dove to discover whether the Flood waters had receded. On its second release, the dove came back in the evening with an olive leaf in its beak. Noah understood this as evidence that the waters were diminishing from the earth. A later release did not bring the dove back.
The raven was sent first, so it is a frequent answer mix-up. The text specifically identifies the returning bird as a dove and the plant material as an olive leaf. The olive branch later became a widely recognized symbol of peace, but Genesis’s immediate point is practical: the leaf showed that vegetation was visible again after the Flood.
