I know this isn't scientific, but for those who may entertain the idea of a Creator, there's a mention of crow behaviour in the Quran, where it describes the story of Abel and Cain (sons of Adam and Eve), and how after Cain killed his brother, God sent a crow to teach him about burial:

    "Then Allah sent a crow searching in the ground to show him how to hide the disgrace of his brother. He said, “O woe to me! Have I failed to be like this crow and hide the body of my brother?” And he became of the regretful." (5:31)
