Red-naped ibis (Cò quăm cánh xanh or Cò quăm đen Ấn Độ or cò quăm gáy đỏ, Pseudibis papillosa) also known as the Indian black ibis or black ibis

The red-naped ibis (Pseudibis papillosa), also known as the Indian black ibis or black ibis, is a species of ibis found in the plains, agriculture fields and cities of the Indian subcontinent.

Pelecaniformes translates to "pelican-shaped" or "pelican-formed," derived from the New Latin Pelecanus (pelican) + -iformes (having the form of). The term originates from the Ancient Greek pelekan (πελεκάν), which is linked to pelekys (πέλεκυς), meaning "axe," likely referencing the large, axe-like bill of the bird.

Threskiornithidae, the scientific family name for ibises and spoonbills, originates from Ancient Greek and New Latin, meaning "religious bird" or "worshipper bird". It is derived from thrēskeia (Greek for "religion" or "worship") and ornis (Greek for "bird"), likely referring to the sacred status of the ibis in ancient Egypt.

Pseudibis is a scientific genus name for a group of Southeast Asian ibises, derived from a combination of Greek and Latin meaning "false ibis". The prefix Pseudo- originates from Greek pseudos, meaning "false" or "lying," and ibis comes from the Latin/Greek term for the bird. 

Papillosa is a Latin-derived botanical and zoological term meaning "full of nipples," "pimpled," or "covered in small, raised projections" (papillae). It originates from the Latin papilla (nipple or pimple) and the suffix -osa, meaning "full of" or "abundant in".
