3. Feathers

   Linked via "flight"

   Feathers?) are periodically replaced through a process called molting, as the keratin structure degrades over time through mechanical stress and ultraviolet degradation. Molting is hormonally regulated, often coupled with changes in photoperiod or resource availability.
   In many passerines, molting occurs asynchronously to minimi…
