Morphology

fish + duck

The compound is transparently compositional: 'fish' modifies 'duck' to indicate a type of duck associated with fish (i.e. a fish-eating or fish-hunting duck). This noun+noun modifier pattern is a standard and cross-linguistically common way to form animal types, so a B1 learner who knows both constituents would readily infer the meaning.

Etymology

Fish duck comes from a simple picture: it is a duck that catches fish by diving and using a saw-like bill to hold slippery fish, so the name shows it 'eats fish'.
