Chestnut-throated Huet-huet (Pteroptochos castaneus) [XC459777]
by Cristian Pinto from Reserva Nacional Altos de Lircay, VII Region., Chile (alarm call)
Forms a superspecies with Black-throated Huet-huet (Pteroptochos tarnii), 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, contrary to earlier beliefs, the upper R Bío Bío does not represent an effective dispersal barrier, suggesting that the two have been in contact several times during fluctuating climatic conditions.
