Just as people make seasonal wardrobe changes, many birds are beginning a transformation of their own, losing and replacing their feathers in a process known as molting.
Molting is when a bird replaces some (partial molt) or all (full molt) of its feathers.
This complicated process requires a lot of energy and may take up to eight weeks to complete. Molting is so physically demanding for most ducks and geese that they canít fly and will molt in seclusion to avoid predators.
Molting season varies by species and time of year. Right now many birds are beginning their main molt of the year, however, American Goldfinches (pictured above) are one of the last to molt. Due to their late nesting period, they wonít start their molt until late August.
Distinguishing birds that are molting from those that are not can be difficult. Though some birds may lose patches of feathers and appear ìbalding,î most birdsí feather loss and replacement are far less noticeable.
Feathers are made of more than 90% protein, primarily keratins, so every molting bird needs extra proteins to grow strong feathers for proper flight and effective insulation.
For the next few months, offer high-protein bird foods, such as Nyjer® (thistle), peanuts, Jim's Birdaciousr® Bark Butterr® and mealworms, to ensure that your birds have a reliable source of protein to help them with molting.
