How Far Can a Siamang's Call Travel?

💡 The Answer

• Siamang calls can be heard up to 3 kilometers (2 miles) away in the rainforest.
• Their loudness is due to the resonance of their throat sac and powerful lungs.
• Calls are used to defend territory and maintain pair bonds.
• The "great call" duet between mated pairs strengthens their bond.
