Passeriformes originates from New Latin, combining the Latin passer ("sparrow") and -iformes ("having the form of"). It translates to "sparrow-shaped" or "sparrow-like", referring to the largest order of birds (over 5,000 species) that includes songbirds and perching birds.

Fringillidae, Fringilla: Latin fringilla for finch.

The name Eophona is derived from the classical Greek words eos meaning "dawn" and phone meaning "shout" or "cry".

The specific epithet "Migratoria" (feminine) or migratorius (masculine) is a Latin-derived term meaning "migratory," "wandering," or "moving from one place to another". It stems from the Latin verb migrāre ("to move," "depart") and the suffix -tōrius (indicating relationship).
