Morphology

Circus + cyaneus

This is a scientific Latin binomial rather than a compositional English phrase: 'Circus' here is a taxonomic genus and 'cyaneus' is a Latin species epithet (not a common English word and absent from the dictionary entry). A B1 learner who knows everyday English words would not be able to derive that this names a specific harrier species from the constituents alone, so the expression is opaque.

Etymology

Circus cyaneus comes from Latin words that describe the bird. The first part, Circus, comes from a word for a 'circle' because the bird often flies in circles, and cyaneus means 'blue' for its grey-blue color, so the name gives a simple picture to help you remember the bird.
