Morphology
Although the phrase is composed of transparent words 'night' and 'raven', a B1 learner would naturally interpret it as a raven (a corvid) that is active at night. The provided meaning — a night-active heron — does not follow from the literal constituents and is therefore unpredictable and misleading for learners, making the MWE idiomatic rather than compositional.
Etymology
Night raven comes from the picture of a dark, raven-like bird hunting at dusk. People used night for the time and raven for the dark, quiet look, so the name means a heron that is 'active at night'.
