What is "chofa"

Chofa (; lit. sky tassel) is a Thai architectural decorative ornament that adorns the top at the end of wat and palace roofs in most Southeast Asian countries, such as Thailand, Cambodia, Laos, and Myanmar. It resembles a tall thin bird and looks hornlike. The chofa is generally believed to represent the mythical creature Garuda, half bird and half man, who is the vehicle of the Hindu god Vishnu.
