Morphology

Procellaria + aequinoctialis

This is a Latin binomial (scientific name). Even if a learner knows 'Procellaria' as a genus of petrels, the second element is a Latin adjective not part of general English vocabulary and the full descriptive meaning (a particular large black petrel with a white chin mark) is not transparently derivable. Scientific names act as fixed labels rather than compositional English phrases, so a B1 learner would not reliably infer the species meaning from the constituents.

Etymology

Procellaria aequinoctialis comes from old Latin words that paint a picture: Procellaria means 'storm' and aequinoctialis means 'of the equator' or 'of the equinox'. That's why the name fits a sea bird often seen in rough southern waters and following ships — the large black petrel with a white chin.
