Range and natural history
FishBase retains the combination Etheostoma douglasi, while ITIS explicitly lists it as a synonym of Nothonotus douglasi. The taxonomic connection is documented, rather than inferred from a shared common name.
The reviewed species summary gives Alabama as its distribution and notes that migratory behavior has not been determined. It does not establish a seasonal movement pattern, so the available evidence supports a regional species overview rather than a detailed migration account.
