Population
Estimated population is unknown (2011).
Black-throated Huet-huet (Pteroptochos tarnii) [XC328249]
by Peter Boesman from Parque Nacional Alerce Andino - Sendero a Lago Sargazo - RDLL, Chile (begging call, call, song, dialogo colectivo)
Black-throated Huet-huet (Pteroptochos tarnii) [XC529883]
by Ignacio Escobar from Curacaut\u00edn, Malleco, Araucan\u00eda, Chile (alarm call)
Forms a superspecies with Chestnut-throated Huet-huet (Pteroptochos castaneus), and formerly considered conspecific. The two are geographically separated in western Argentina (Neuquén) by a distance of over 200 km. Recent studies have shown, however, that, despite earlier theories, the upper R Bío Bío is not an effective barrier to dispersal, suggesting that the two taxa have been in contact several times during fluctuating climatic conditions.
