Found in ” You’re ” by Sylvia Plath’s “trawling your dark as owls do ” (Line 6)

Knowing the definition helped me understand the simile and how the unborn child is being compared to an owl. Owls are nocturnal animals they’re active in the dark and the a growing fetus is in the dark during pregnancy and is feeding from a tube. The owl and the unborn child has a lot in common.
