Steatornis Caripensis, commonly known as the oilbird or guácharo, is a unique species of nocturnal bird found in South and Central America. While there are no direct synonyms for this species name, it is often referred to by its common names or other descriptions. For example, the oilbird is also known as the "rain bird" due to its activity during rainy nights and its ability to navigate using echolocation. Additionally, it is sometimes called the "avocado bird" because it feeds on the fruit of the avocado tree. Some descriptive synonyms could include "nocturnal bird of the tropics" or "large, fat bird with unique adaptations for living in caves.".
