As of today, out of season, returns ~November. Earth Exhibit tracks the live conditions and flags it the moment it is on.
At Nam Cát Tiên (Cat Tien) National Park, southern yellow-cheeked crested gibbons (Nomascus gabriellae) produce loud, coordinated dawn duets each morning.
The calling bout is concentrated in the 30–60 minutes around sunrise and is audible across forest ridgelines; guided dawn treks and the Dao Tien primate centre are the primary ways visitors reliably experience the chorus.
