Range & habitat

They also reside in partially deciduous hill forests as well as broadleaf pine forests, and can be found as high as 2,700 m in elevation in northeastern Myanmar. The eastern hoolock gibbon has been found in tropical environments that experience monsoon rains and have cool, dry winters. and lowland tropical environments. The eastern hoolock gibbon is an omnivorous animal, with fruits making up the majority of its diet at about 65%, with 60% of the fruits being figs. They also eat lichens, invertebrates, bird eggs, plant parts (buds, shoots, leaves, flowers), and insects. The majority of what they eat depends on their location and the density of the available resources, but fruits always show to be their most dominant food type. Gibbon groups sleep in trees that are close to each other, focusing on the tallest canopy trees, and tend to choose areas located either on hilltops or slopes. They also sleep in a fetal position with their arms hugging their knees into their chests. Gibbons are more active in the summer, awaking earlier in the day than in the winter, and socialize more with each other while being awake for about 8–10 hours a day, sleeping shortly before dusk arrives. …
