Behaviour
The red-faced spider monkey exhibits a fission-fusion society, associating with large groups of up to 30 individuals during the night, but choosing to spend the days travelling, foraging, and resting in much smaller groups. At dusk, they recongregate using a greeting call to communicate. At night, they often sleep in large groups called bands. Bands typically consist of several females, with their respective young, along with a few males for protection. The only range size estimate was 255 hectares (630 acres), of which 220 ha (540 acres) had suitable habitat.
The red-faced spider monkey feeds on a variety of foods and would be considered an omnivore. It will eat termites and grubs, but also feeds on supple leaves, flowers, berries and fruit.
It has a gestation period of 226–232 days, is weaned after four or five years when it reaches sexual maturity, and has a life span of up to 33 years in captivity.

Famous quotes containing the word behaviour:
“When we read of human beings behaving in certain ways, with the approval of the author, who gives his benediction to this behaviour by his attitude towards the result of the behaviour arranged by himself, we can be influenced towards behaving in the same way.”
—T.S. (Thomas Stearns)
“I cannot be much pleased without an appearance of truth; at least of possibility—I wish the history to be natural though the sentiments are refined; and the characters to be probable, though their behaviour is excelling.”
—Frances Burney (1752–1840)
“The methodological advice to interpret in a way that optimizes agreement should not be conceived as resting on a charitable assumption about human intelligence that might turn out to be false. If we cannot find a way to interpret the utterances and other behaviour of a creature as revealing a set of beliefs largely consistent and true by our standards, we have no reason to count that creature as rational, as having beliefs, or as saying anything.”
—Donald Davidson (b. 1917)
