According to the Bible, after the great flood, Noah sent out a bird to search for dry land. The first bird that Noah sent out was a raven. The raven flew out and did not return to the ark because it was able to find food and a place to perch on the floating debris.
Later on, Noah sent out a dove to search for dry land. The dove initially found no place to rest, so it returned to the ark. Noah waited for a week and sent the dove out again, and this time it returned with an olive leaf in its beak, indicating that there was now dry land with trees growing on it. Noah waited for another week and sent the dove out again, and this time it did not return because it had found a suitable place to live.
So to sum up, the first bird that Noah sent out was a raven, but it was the dove that eventually found dry land and helped Noah and his family to safely leave the ark after the flood.
