Northern Grey Gibbon Sounds & Calls
Similar to other gibbon species, Northern Grey Gibbons are highly vocal. The ‘great call’ of the female is characterized by accelerating whoops followed by a rapid series of bubbly notes. Male-female duets are an iconic sound of the Bornean rainforest at dawn.

Due to the rampant destruction of Borneo’s lowland tropical rainforests, the Northern Grey Gibbon has suffered significant population loss and is now considered endangered. The expansion of oil palm plantations throughout Borneo is an ongoing threat to this species as well as countless others which depend on rainforest for their survival.
