Nasua narica, commonly known as the white-nosed coati, is native to the Americas, specifically found from the southwestern United States (southern Arizona, New Mexico, and Texas) through Mexico and Central America down to Colombia and Ecuador in South America.

The white-nosed coati primarily inhabits tropical and subtropical forests, including both dry and moist forest types. They are also found in woodlands and scrub areas. The typical climate in these regions ranges from warm to hot with varying amounts of precipitation depending on the altitude and specific locality.

The coati is an omnivorous mammal that plays a significant role in its ecosystem as both a predator and prey. It typically feeds on insects, fruits, small vertebrates, and eggs. The coati is known for its adaptability to different environments and complex social structures, often forming bands that help in foraging and protection.
