Noah first sent out a raven from Noah’s Ark, before sending a dove.
Genesis 8:7 says Noah sent a raven after the floodwaters began to decrease. The raven went back and forth until the waters had dried from the earth. Noah then sent a dove to determine whether the surface had become clear; that bird later returned with an olive leaf.
The two birds serve different narrative functions. The raven appears first and is described as continuing to fly back and forth, while the dove’s successive returns provide more specific signs about the changing conditions outside. Because the dove and olive leaf are so famous, people sometimes remember the dove as the only bird Noah released.
The answer is raven, not eagle or pigeon. In ordinary modern speech, “pigeon” can be used loosely for dove-like birds, but Genesis explicitly names a raven and a dove.
