Genesis 8:10

Also he sent forth a dove from him, to see if the waters were abated from off the face of the ground;

But the dove found no rest for the sole of her foot, and she returned unto him into the ark, for the waters [were] on the face of the whole earth: then he put forth his hand, and took her, and pulled her in unto him into the ark.

And the dove came in to him in the evening; and, lo, in her mouth [was] an olive leaf pluckt off: so Noah knew that the waters were abated from off the earth.

And he stayed yet other seven days; and sent forth the dove; which returned not again unto him any more.
