- proper n. A taxonomic family within the order Procellariiformes — the petrels, fulmars, shearwaters, etc.
But before too long we got to sentences like, "Fulmars are more robust than Shearwaters," and I couldn't help but thinking this was all a complex world-building sort of scheme, where the Procellariidae were in contention with the Sulidae for the Emperor's ear.
This is the case with species of shearwater, such as Puffinus puffinus (Procellariidae), which nest in gullies of laurisilva.
Procellariidae: Long, narrow wings, fully extended, slim hooked bill, all dark or dark with white underparts, paired tubular nostrils.
Procellariidae: Long wings, bent at wrists, heavy hooked bill, erratic flight, highly pelagic, all dark or dark with white underparts.
