Morphology
The sense 'to lower your body quickly' is directly and compositionally built from the verb sense of 'duck' (to lower/crouch) combined with 'down' (to a lower position), so a learner who knows the constituent meanings can infer the action. Although 'duck' is listed here as a noun, the relevant verb sense is common and the motion/position combination is cross-linguistically familiar, making the expression immediately comprehensible.
Etymology
The noun duck down is the very soft, fine feathers from a duck, the warm, fuzzy layer under its outer feathers, and people use this material to fill pillows and jackets, so it means 'soft filling for warm clothes and bedding'.
