A White Cheeked Gibbon
How gibbons act
the real truth is white-cheeked gibbons are social and active during the day. Gibbons sleep at night high in the trees sitting upright holding each other tightly. Gibbons are very vocal and that is how they communicate with one another. When they make calls they will often do a type of acrobat associated with that call. Adult female gibbons tend to be the boss in their family. Gibbons are very territorial and let the others know where their area is.
