What process in birds helps to keep feathers in good condition?

1. Molt

2. Preening

3. Bathing

4. Dusting

The correct answer is: Preening

Preening is the process in birds that plays a crucial role in maintaining the condition of their feathers. During preening, birds use their beaks to groom their feathers, redistributing natural oils produced by their skin. These oils provide waterproofing and help to keep the feathers flexible and resilient. Additionally, preening helps remove dirt, parasites, and loose or damaged feathers, ensuring that the bird's plumage remains in optimal condition for insulation and flight. This behavior is essential for birds not only for physical appearance but also for their overall health, as clean and well-maintained feathers are vital for effective thermoregulation and flight performance. While the other options like molting, bathing, and dusting contribute to feather care in different ways—such as replacing old or damaged feathers, removing excess oil or dirt, and managing feather mites respectively—preening is the primary behavior that directly keeps feathers in good condition on a daily basis.
