Morphology

Steatornis + caripensis

This is a taxonomic binomial (genus + species). Knowing 'Steatornis' lets a learner infer it is a kind of Steatornis (i.e. a particular bird), so the general category is compositional, but the species epithet 'caripensis' and the detailed species traits (nocturnal, fruit‑eating, fatty young) are technical/Latin and not predictable from the parts for a B1 learner. Because the name tells you the type of organism but not the specific behaviors or cultural uses, it is only partially transparent.

Etymology

Steatornis caripensis comes from older words that mean 'fat' (the part steato-) and 'bird' (the part -ornis), while 'caripensis' refers to Caripe, the place where the bird was first noted. So the name paints a clear picture of a 'fat bird from Caripe', which fits the species whose oily young were once used like 'butter'.
