turtle <SON2 -12> The flowers appear on the earth; the time of the singing [of birds] is come, and the voice of the {turtle} is heard in our land;
turtle <JER8 -7> Yea, the stork in the heaven knoweth her appointed times; and the {turtle} and the crane and the swallow observe the time of their coming; but my people know not the judgment of the LORD.
