doubleplumed

Doubleplumed is an English adjective used to describe something characterized by two distinct plume-like projections or feather-like structures. The term is compound, formed from double and plume, and is used primarily as a descriptive label rather than a formal technical category. It is encountered across several domains where paired feather-like features are noted.

In biology and zoology, doubleplumed describes organisms or parts that have two prominent plumose appendages, such as paired tail filaments or head plumes in certain species. In ornithology, it could be used for birds with two crests or decorative head plumes observed in certain plumages or display phases; however, it is not a standard taxonomic term and its use is descriptive.

In heraldry and insignia, the term may appear to describe devices, crests, or tassels that feature a pair of plumes, often used to convey symmetry, duality, or affiliation. In fashion, textiles, and art, doubleplumed can describe items with two feathered or feather-like projections, such as a hat ornament or necklace motif.

Because doubleplumed is not a formal designation, its precise meaning depends on context, and it should be clarified by accompanying description or imagery. See also plume, plumage, crest, feather tufts.
