The term 'Grooms, as Plumes' is a reference to the job of a preen, which is a person who takes care of the feathers of birds. Preening is an important part of a bird's grooming process, and it involves cleaning, oiling, and arranging the feathers in order to keep them healthy and in good condition. The term 'Grooms, as Plumes' is a metaphor for the job of a preen, as they groom the feathers of birds in the same way that a groom would groom the plumes of a horse.
