The feathers of a parrot can exhibit duller coloration, darkening of the color, colored bands, or stripes. Each of these changes has different underlying causes.
A healthy parrot will have strong, well-groomed, and colorful plumage, while an unhealthy parrot will show at least one symptom through its feathers. Parrot feathers can become gray, black, yellow, white, brown, or lose their luster. Liver diseases and vitamin A deficiencies are common causes of feather discoloration in parrots.
If the feathers are only slightly discolored, your parrot is preparing to molt. If it is undergoing medical treatment or is stressed, your parrot may develop bands on its feathers. This most often occurs when it is losing feathers to regrow new ones. Once the cause of the banding is resolved, the feathers regrow normally.
Feather Discoloration in Parrots
Parrots cannot choose to modify the color of their feathers. They cannot lighten or darken them, switch from one color to another, or introduce new patterns. However, feathers can change and discolor based on their health status.
Wild parrots use the color and luster of their feathers to select healthy mates during the breeding season.
What Do the Feathers of a Healthy Parrot Look Like?
The feathers of a healthy parrot should have a single, uninterrupted shaft.
The feather itself should be free of debris, shiny, and the barbs should be interconnected. The colors should be bright and clean, and the feather should be soft to the touch.
Parrots have a wide range of colors, and most have multiple colors in their overall plumage. As long as the coloration matches the rest of their body and the patterns they naturally display, they are in good mental and physical health.
What Do the Feathers of an Unhealthy Parrot Look Like?
The feathers of an unhealthy parrot have strange or dull coloration and appear.. :
- Bare
- Frayed
- Malformed
- Curved
- Broken
- Strange shapes
They may feel dry or brittle to the touch. This may correspond to unusual shapes, such as:
- Stripes
- Banding
- Splashes
Why Have My Parrot’s Feathers Changed Color?
There are several reasons why a parrot’s feathers may change color, including:
Maturity
The feathers of a young parrot change color as it grows and molts its juvenile down feathers.
The down feathers of most parrots are a mix of white and gray. When these soft, fluffy feathers are shed, they are replaced by those of an adult parrot.
These new feathers should be bright, strong, and sleek. Their colors will match the normal tones of their species, with some normal variations.
The feathers of a parrot do not change naturally after losing down, except for the following reasons:
Health
A disease or nutritional deficiencies can cause markers to appear on growing feathers, such as:
- Stripes or bands
- Discoloration spots
- Discolored sections
Various health problems can lead to a change in the color of a parrot’s feathers, including:
Nutritional deficiencies can interfere with how the body produces pigments and feathers. This may be due to a lack of vitamin A, sunlight, and proteins. Likewise, an excess of fat can cause the feathers to darken.
Feather Follicles
Feather follicles are delicate structures, and any damage or irritation can interfere with their regrowth.
The feather may be misshapen, limiting its ability to reflect light. When the nanostructures are malformed, colors like blue become paler. Thus, even a slight distortion can lead to a lack of color.
Although many things can damage the follicles, the most common reason is feather plucking. Feathers fall out naturally and are regrown when they are too old, and prematurely or harshly pulled feathers can cause irreversible damage.
Trauma can cause inflammation or infection of the follicles. If your parrot has fought, that spot may not recover.
Molting
The molting process allows the shedding of old feathers and replacement with new ones.
When a feather reaches the end of its life, it may take on a frayed appearance with duller coloration. In contrast, the new feathers that are growing will be brighter and more colorful.
Depending on their species, parrots molt 1 to 3 times a year. Monitoring your parrot during a molt is a good way to check a parrot’s health.
How Do Parrots’ Feathers Change Color?
Parrots do not naturally change color, but they take on their colors as they age. This is because all feathers contain pigments, known as chemical coloration.
These pigments react to the hormones and chemicals present in the parrot’s body as it matures. The pigments can change hue or transform into entirely new colors.
Parrot feathers contain pigments called psittacofulvins. These are bright red, orange, and yellow pigments found only in parrots.
Other families of pigments include:
- Melanins
- Porphyrins
- Carotenoids
Carotenoid pigments constitute the same colors as psittacofulvins. These come from the ingestion of plant material. However, even though carotenoid sources are a significant part of a parrot’s diet, the plumage of this species is not affected by food.
The coloration of a parrot’s feathers is affected by the reflection of light, known as structural coloration. Most parrots have a combination of structural and chemical coloration. For example, blue feathers are not created by a pigment. Instead, they form due to light reflection in the nanostructures inside each feather.
As most tones are affected by a parrot’s chemical balance, disease can impact its feathers. In cases of malnutrition and stress, the structure of the feathers will be damaged, and you may notice fraying and banding.
Parrots’ Feathers Take on a Different Color
There are a few reasons why a parrot’s feathers may change color. Although it is not a hard and fast rule for all species, the new coloration may help you assess the reason for this change.
Turning Black
Have your parrot’s feathers darkened significantly or turned black?
If so, this is a warning sign that the parrot has an excess of fat or protein in its body. A vitamin A deficiency can also cause black tips and edges on feathers, but the same applies to lightened feathers.
Turning Yellow
Cockatiels with liver disease may develop bright yellow feathers instead of black feathers. Diseases such as hepatic steatosis can be fatal if not resolved.
Turning Brown
Parrots need to bathe several times a week. Dirt and grime can give feathers a slightly brown appearance.
Check your parrot’s favorite perches. Are they covered in droppings and dirt? If so, clean them as the debris is likely staining the feathers.
Turning Gray or Dull
The feathers of a parrot begin to dull when it is preparing to molt.
The feathers then become gray or ash-colored. An excess of parrot dust can dull or gray the natural vibrancy of the plumage, giving the feathers a white appearance.
Shredded or Frayed
A disease requiring medical treatment may cause new feathers to grow with markers or different colors.
For example, African greys sometimes have scattered red feathers in their plumage due to damaged follicles or medication. These feathers return to normal after molting.
Patchy feathers of different colors, shredded or damaged can indicate an injury or infection of the skin or feather follicle.
Parasites can lead to irritation. A parrot may over-preen or bite the area, which will further irritate the skin and feathers.
How to Improve the Quality of Parrots’ Feathers?
To help your parrot maintain healthy feathers, provide proper care in all aspects of its life. This includes its diet, environment, and access to sunlight.
Avoid Stress
Long periods of stress are responsible for the formation of feather bands, leading to behavioral problems and feather plucking. A stressed parrot is likely unhappy, bored, or feeling lonely.
Place the parrot’s cage in a room without activity or noise. Your parrot will find that destabilizing.
Ensure that the cage is large enough, with toys and enrichment items. If you make changes, do so gradually.
A socialized parrot is a happy and stress-free parrot. Spend time with your parrot and allow it to join you in other parts of the home, for example, by offering it a perch in the living room.
Keep the cage away from any vents, fans, or air conditioning units. These airflows can be stressful and are known to dry out parrots’ feathers and skin.
Diet
Although parrots do not rely on food for their pigmentation, diet plays a crucial role in maintaining healthy feathers. To promote feather health, provide foods rich in vitamin A.
Foods high in vitamin A include:
Exercise
Preventing obesity and its associated diseases requires a balanced diet and exercise. A happy parrot needs mental and physical exercise through socialization, play, and puzzle toys.
An enriched parrot will be more active and will not feel the need to pluck its feathers due to stress or boredom.
Sunlight
Sunlight is essential for maintaining strong, vibrant, and healthy feathers.
Place part of your parrot’s cage in an area that has access to direct sunlight. UVB lamps are an alternative to sunlight. Remember that after 6 months of use, the light will stop producing UVB rays.
