Can birds change feather color?
A change in a bird’s feather coloration is not always the result of a genetic mutation.

What does it look like when a bird has a molt?
The new feathers, then, create visible gaps in a bird’s plumage, particularly in the wings and tail, where shorter feathers are more noticeable. On the body, nearby feathers overlap the bare space so the bird’s skin is not exposed, but the bird may look scruffy and its markings will be indistinct until the molt is complete.
