Bird Feather Health and Anatomy


Most people associate feathers with flying, but did you know that feathers have numerous functions besides enabling a bird to fly? Feathers also help birds regulate body temperature, protect themselves from the wind and sun, and send signals to mates or rivals. Birds in the wild use their feathers to transport water, build nests, swim, and more!

Your bird's feathers are a good indicator of his overall health. The growth of healthy and vibrant feathers requires numerous nutrients and vitamins. Feathers should be soft, smooth, full, vivid, and clean. If your bird's feathers are lacking one of these characteristics, there may be something wrong. Certain diseases, like fatty liver syndrome, and viruses can cause abnormally colored feathers.

Feather Anatomy

Feathers develop within a follicle; while a feather is growing, there is an artery and a vein that extend throughout the feather and help nourish it. This is called a blood feather. When one of these feathers is accidentally cut during a wing trim, it will bleed. Once a feather is done growing, the vessels will recede and shrivel up. Birds usually molt once or twice a year. During this time, the bird's feathers will be replaced with new ones.

At some point, you may notice abnormal lines that run perpendicular along the feathers; these are called stress bars. They develop when the feather is still growing, and they are usually caused by stress, anxiety, or malnutrition. If you notice that your bird has stress feathers, you should analyze his diet and make sure that he is receiving needed vitamins and minerals. You should also evaluate your bird's environment and behavior. If the condition is corrected, the stress bars should disappear the next time your bird molts.

To Ensure Healthy Feathers

To ensure that your bird's feather and skin remain healthy, make sure that he is receiving proper nutrition, including necessary vitamins and minerals. Even if you feed your bird a formulated diet, he may still need supplements for ultimate feather health.

Birds also need moisture and light in order to keep their feathers healthy and vibrant. Full-spectrum lighting ensures that your bird is receiving the light that he needs to maintain healthy feathers. Humidifiers and extra bathing are helpful for receiving moisture, especially in the winter months when the air is dry. If a bird isn't receiving enough moisture, his skin and feathers will become dry, and he may start feather picking.

It's important to take time to inspect your bird's feathers, ensuring that they look healthy and vibrant. You should analyze your bird's diet, environment, and behavior if you notice that his feathers look dull, dirty, or ragged. If his feathers don't return to normal, take him to the avian veterinarian.
