What does "to moult" refer to in hawks?

To moult refers to the process in which hawks shed their old feathers to make way for new growth. This is a natural and vital part of their life cycle, allowing them to maintain optimal flight capabilities and insulation. Feathers can become worn or damaged over time, and regular moulting ensures that birds of prey like hawks have the best possible plumage for hunting and survival.

During moult, a hawk will gradually replace its feathers. This typically occurs in a predictable seasonal pattern and can take several weeks to complete. Healthy feather conditions are vital for flight performance and the bird's overall health, emphasizing the importance of this process in a hawk's life.
