What is a tiercel?

A tiercel specifically refers to a male falcon, particularly in species such as the peregrine falcon. This term is derived from the fact that male birds, particularly falcons, are typically smaller than their female counterparts and are often recognized by the suffix '-cel' which is derived from a Latin word meaning "third." In avian terms, the male is considered to be the "third" in size compared to the female. In many species of raptors, such as the peregrine falcon, it is a common practice in falconry to differentiate the males and females due to their size and behavioral characteristics.

Other options such as a type of raptor's leg, a female peregrine falcon, and a hunting technique used by falcons do not accurately define what a tiercel is, as they refer to different aspects of falconry and raptor biology. Understanding the terminology is crucial for effective communication and successful practices in the field of falconry.
