Birds Molting Their Feathers

Molting Bird

Although their structure is different, a bird’s feathers can be compared to hair and nails in humans. Just as hair and nails are renewed, old, worn, damaged feathers are replaced by new ones through the process called molting.

Hormones play a part in molting s do changes of season. New feathers can identify the sex of some species and their ages.

Molting patterns vary depending on where a species of bird lives. There are two stages of molting. A complete molt is when all the feathers are replaced. A partial molt replaces only some feathers. Feathers that are lost are replaced quickly by new ones and a bird is never without plumage.

The number of times a bird molts during the year depends on the species. There are many variables and exceptions to molting patterns even within an individual species. Plumage coloring can change with the seasons.

Bird-watching is a very popular past-time and you can glean lots of information about birds who visit your own backyard.
