The genus Pharomachrus, including the Resplendent Quetzal, is known for its vibrant plumage and long tail feathers. These birds inhabit cloud forests in Central America, feeding on fruits, insects, and small animals. They are crucial seed dispersers in their ecosystem. Euptilotis, including the Eared Quetzal, shares similar habitats but is found in Mexico and the southwestern United States.

Pharomachrus (Quetzals) and Euptilotis (Eared Quetzal) are found in the Neotropical region, primarily across Central America and parts of South America. These species are native to countries such as Mexico, Guatemala, Costa Rica, Honduras, Nicaragua, Panama, and parts of the Andes in South America.

Quetzals typically inhabit cloud forests and montane forests at elevations ranging from 1,200 to 3,000 meters (3,937 to 9,843 feet). These environments are characterized by high humidity, frequent mist, and dense vegetation, including epiphyte-laden trees.

Quetzals are primarily frugivorous, feeding on a variety of fruits, especially those from the Lauraceae family. They also consume insects and small vertebrates. Their ecological niche is that of a canopy dweller, playing a crucial role in seed dispersal, particularly in cloud forest ecosystems.
