a dove or pigeon, specifically the common rock dove and its young: the affordable altar-bird for the poor and a frequent image of tenderness, grief, and swift flight
Yonah is the everyday Hebrew word for the dove or pigeon, most likely named for the soft cooing sound the bird makes. It always refers to the same literal creature, the common rock dove that nested in cliffs and was kept in dovecotes for food and for sacrifice.
The reason one plain word carries such a wide range is that biblical writers watched the bird closely and drew on its real habits. Because the dove was cheap and widely raised, it became the offering a poor worshipper could afford. Because it is gentle and prized, it became a pet name for the beloved. Because its call is a low moan, it became the standard image of grief. Because it flies fast and homes back to its nest, it pictures both escape from danger and exiles coming back. And because it can flutter about in blind panic, it could even stand for a foolish, easily led people.
So the different uses are not different words but different sides of one familiar bird. The literal dove of the flood story and the sacrificial pigeon of the law sit alongside the dove of love poetry, the mourning dove of the prophets, and the homing dove of return, all held together by the creature itself.
Nuances
Whether the dove-imagery for the beloved's eyes evokes the Ancient Near Eastern love goddess, for whom the dove was a sacred messenger, or simply conveys gentleness, beauty, or the fluttering motion of a glance.

- contestedThe image is evocative rather than allegorical, conveying beauty, gentleness, or the darting motion of the eyes without invoking a goddess cult.; Michael V. Fox, The Song of Songs and the Ancient Egyptian Love Songs; J. Cheryl Exum, Song of Songs (Old Testament Library)
