Well, there have been two more
owls in ULYSSES. I don't need to remind YOU that
it's not my responsibility to tell you EVERY time an owl appears in a book, but the third owl is unusual enough to warrant comment, plus it is an actual owl, not - like the first two - a figurative one. It sits on the mantelpiece of Mr. Bloom, "an embalmed owl, matrimonial gift of Alderman John Hooper" with a "clear melancholy wise bright motionless compassionate gaze."
