Blacknaped

Blacknaped is an informal term used in natural history to describe organisms that possess a distinctive black patch on the nape, the back of the neck. The term is most commonly found in common names of species, where it signals a characteristic marking used for identification and distinction from related species. The spelling varies by source, with black-naped and Blacknaped used interchangeably; concatenated forms are sometimes seen in older literature or catalog entries.

Because Blacknaped is not a formal taxonomic term, it does not refer to a single species or group. Instead, it appears in multiple, independent lineages across different taxa. In birds, several species receive common names that include "black-naped" to indicate a dorsal neck patch. In other groups, comparable naming patterns exist for mammals, reptiles, and insects with similar markings. Field guides and checklists may differ in whether the term is hyphenated or not.

Taxonomic treatment of individual "black-naped" species follows standard practice for their respective groups, with genus and species names provided for precise identification. The feature often holds ecological or behavioral relevance in species recognition, mating displays, or camouflage, though the exact function varies by lineage.
