What is the primary function of the molting process in female ducks?

The primary function of the molting process in female ducks is to replace worn feathers. Over time, feathers can become damaged and lose their insulating and waterproofing properties. Molting allows ducks to shed these old feathers and grow new, healthy ones, which are essential for maintaining flight capability and effective insulation from the elements.

While improving flight can be a secondary benefit after molting due to the fresh set of feathers, the primary purpose is to ensure the duck’s plumage is in good condition. Similarly, although new feathers can assist in regulating body temperature and may play a role in attracting mates, the main goal during the molting process is the replacement of feathers to sustain their overall health and functionality.
