What term describes the process of a raptor's feathers being replaced over time?

The process of a raptor's feathers being replaced over time is known as molting. This biological process involves the shedding of old feathers to make way for new ones, which is crucial for the bird's health and functionality. Feathers are essential for insulation, waterproofing, and flight performance, so molting allows the bird to maintain optimal physical condition.

During molting, raptors systematically replace feathers in a way that ensures they can continue to fly and hunt effectively. This process usually occurs seasonally or annually, depending on the species and environmental conditions. In contrast, the other terms provided refer to different concepts; for instance, imping involves repairing damaged feathers, breeding relates to reproduction, and hacking is a method used in falconry where young birds are reintroduced into the wild. Understanding molting helps falconers appreciate the avian care needs throughout the year.
