NOTES: Breeding status: Territorial. LNS Notes: AOU Part 11 notes that Escalante-Pliego (1992) considered auricularis (with peruviana) of western Peru and Ecuador and the velata subspecies group of southern South America as separate species from Geothlypis aequinoctialis, as they had been treated by (REF - fide Meyer de Schauensee 1966 - trace). Ridgely & Tudor (1989) pointed out that auricularis (with peruviana) differs in plumage from other aequinoctialis at least as much as do taxa of Geothlypis yellowthroats treated as full species in Middle America. Ridgely & Greenfield (2001) followed Escalante-Pliego (1992) in treating auricularis, velata, and Central American chiriquensis as separate species from aequinoctialis, but see Wetmore et al. (1984). SACC Proposal to elevate auricularis and velata to species rank did not pass due to insufficient published data. Ridgely & Greenfield (2001) also suggested that vocal differences between auricularis and the subspecies peruviana indicated that peruviana should also be recognized as a separate species. We note that North American G. trichas shows remarkable geographic variation in song (BNA REF), and so we urge caution in comparing vocalizations among localities without taking into account potential geographic variation from across the range of any Geothlypis species complex.
