Pitheciidae

The family Pitheciidae is a group of New World monkeys found in South American rainforests. These monkeys are part of the order Primates. The family includes genera such as Callicebus (titis), Pithecia (sakis), Chiropotes (bearded sakis), and Cacajao (uakaris). Titis, for example, are small, arboreal monkeys with long furred tails, typically weighing less than 2 kg. They live in monogamous, territorial groups and forage for fruits, bird eggs, insects, and small vertebrates. While generally omnivorous, primate diets vary, with some species specializing in leaves, fruits, or insects. The term "pithecus" itself derives from the Greek word for ape or monkey.1234
