The collared titi[1], also called the widow monkey, or yellow-handed monkey inhabits the lush rainforests of the Amazon and is typically found south of Río Negro and north of Río Solimões.
- Collared titis are small monkeys with long, glossy black fur on the underside and fading to rusty brown on the back.
- Their hands are light beige or yellow. Their faces are gray, and, in keeping with their name, they have a distinctive white ruff of fur on their necks.
- Their alternate common name, “Widow Monkey” is derived from their pale face, white neck, and “gloved” hands that contrast with their dark body, giving them the appearance of a grieving widow.
- Their tails are long, hairy, and non-prehensile.
