First Question: Is the Bird Actually Losing Feathers—or Damaging Them?

This distinction can immediately narrow the possibilities.

A feather can disappear because:

• It naturally falls during molt
• The bird pulls it out
• The bird chews through it
• A cage mate damages it
• The feather breaks mechanically
• The follicle produces an abnormal feather
• Disease causes abnormal shedding

Look closely at feathers found on the cage floor.

Their condition can tell you almost as much as their number.

What Does a Naturally Molted Feather Look Like?

A naturally shed feather is usually relatively complete.

It may show normal wear at the edges, but it should generally resemble an intact feather rather than something that has been chewed into pieces.

At the same time, healthy replacement feathers should begin appearing from the follicles.

This process—old feathers leaving while new feathers replace them—is the defining feature of a healthy molt.

What Do Plucked or Chewed Feathers Look Like?

Feather-destructive behavior can produce a very different appearance.

Feathers may appear:

• Frayed
• Shredded
• Cut off
• Chewed near the skin
• Damaged only at the tips
• Uneven across one body area

Some birds remove entire feathers.

Others leave the soft down portion behind while destroying the outer feather structure.

The Most Important Difference: Replacement vs Damage

A normal molt is fundamentally a replacement process.

Old feather out → new healthy feather in.

Abnormal feather loss often looks more like:

feather damage → baldness → poor regrowth → repeated damage.

That distinction is more useful than simply counting how many feathers are on the cage floor.

Does Fall Normally Cause Birds to Lose Feathers?

Seasonal feather replacement can certainly occur during late summer and Autumn.

However, species differ considerably.

Some companion birds undergo a noticeable major or partial molt around Autumn.

Others molt at different times.

Artificial indoor lighting can also change normal seasonal timing.

The calendar alone therefore cannot diagnose normal molt.

What Should a Normal Autumn Molt Look Like?

A healthy molt usually has several reassuring characteristics:

• Feather loss develops gradually
• New pin feathers appear
• The bird remains interested in food
• Body weight remains reasonably stable
• There are no dramatic bald areas
• Feathers are not continually chewed apart
• The skin does not appear severely inflamed

The bird may look somewhat untidy for a period, but the overall direction should be toward new plumage.

What Are Pin Feathers?

Pin feathers are newly developing feathers.

They emerge inside a protective keratin sheath and initially appear as narrow spikes or tubes.

They are often easiest to see around the:

• Forehead
• Head
• Neck

These are areas where a bird has difficulty preening itself directly.

Healthy Pin Feathers vs Abnormal Pin Feathers

Healthy pin feathers should eventually mature into normal plumage.

Veterinary evaluation becomes more important when new feathers:

• Repeatedly break
• Grow abnormally
• Remain malformed
• Fall out prematurely
• Fail to develop normally

Persistent abnormal feather development can indicate more than an ordinary molt.

Should a Bird Develop Bald Spots During Molt?

Large obvious bald areas are not the classic pattern of an orderly normal molt.

Some temporary thinning can make the plumage look uneven, but rapidly expanding bare skin should prompt a closer investigation.

Pay particular attention to:

• Chest
• Back
• Under wings
• Legs
• Neck
• Head

The Body Location of Feather Loss Matters

Where feathers disappear can provide important clues.

If a bird is damaging its own feathers, the affected area generally has to be physically reachable by its beak.

Feather loss from areas the bird cannot reach—especially the top of the head—raises different questions.

Possible explanations may include:

• Another bird barbering the feathers
• Follicular disease
• Viral feather disease
• Trauma
• Other medical disorders

What Is Feather Plucking?

The term feather plucking is often used broadly.

Veterinary professionals increasingly use the term feather-destructive behavior because birds may do more than simply pull feathers out.

A bird may:

• Overpreen
• Chew feathers
• Break feathers
• Strip feather material
• Pull feathers completely
• Damage underlying skin in severe cases

Why Do Birds Pluck Their Feathers?

There is rarely one universal cause.

Potential contributors include:

• Stress
• Boredom
• Sexual frustration
• Hormonal behavior
• Insufficient sleep
• Poor environmental enrichment
• Poor nutrition
• Skin disease
• Pain
• Internal medical disease

This is why behavioral plucking should generally be considered only after medical causes are investigated.

Fall Can Change a Bird's Environment Dramatically

Autumn often changes daily household routines.

Windows close.

Heating systems turn on.

Indoor humidity can fall.

Daylight hours shorten.

Family schedules change as summer ends.

A bird may receive less outdoor light or a different amount of social interaction.

For a sensitive bird, several changes occurring at once can affect behavior and skin comfort.

Stress Plucking vs Seasonal Molt

Stress-related feather damage tends to be less orderly than molt.

Look for:

• Repeated attention to the same body area
• Chewed feathers
• Broken shafts
• Progressive bare skin
• Plucking that increases during specific situations

Keeping a behavioral diary can help identify triggers.

Hormonal Feather Plucking

Sexual and reproductive behavior can contribute to feather-destructive behavior in some birds.

Potential clues may include:

• Territorial behavior
• Regurgitating toward a person or object
• Seeking dark nesting spaces
• Increased aggression
• Sexual behavior toward toys or people

Behavioral and environmental management may be necessary in addition to investigating medical causes.

Boredom and Under-Stimulation

Wild birds spend large parts of the day:

• Searching for food
• Flying
• Exploring
• Interacting socially
• Manipulating objects

A highly intelligent companion bird with little to do may redirect its attention toward its own feathers.

Foraging and enrichment should therefore be considered part of preventive feather care.

What Is Overpreening?

Preening is normal.

Overpreening is excessive attention to feathers that begins causing visible damage.

A bird may repeatedly run the same feathers through its beak until the surface becomes ragged or damaged.

The challenge is determining whether the overpreening is primarily behavioral or being driven by irritation, pain or disease.

What Is Barbering?

Barbering occurs when another bird damages a companion's feathers.

This can be confusing because the affected bird may appear to be “plucking” even though another bird is responsible.

Barbering can occur between:

• Pair-bonded birds
• Parents and offspring
• Cage mates

Observe interactions carefully.

How Can You Tell Barbering From Self-Plucking?

Location can provide clues.

If damaged feathers are concentrated around areas the bird itself cannot easily reach, another bird should be considered.

Direct observation is even more useful.

Bird Molting vs Mites

Mites are one of the first explanations many owners consider when they see feather problems.

But parasites are often overestimated as a cause of feather loss in indoor companion birds.

Different mites also produce very different clinical patterns.

Do Feather Mites Commonly Cause Pet Bird Feather Loss?

True feather-mite infestation is relatively uncommon in many indoor pet birds.

Outdoor aviaries and particular housing situations can carry different risks.

That means treating every bird with feather damage for mites is not an appropriate diagnostic shortcut.

Scaly-Face Mites in Budgies

Scaly-face mites are much more recognizable than a simple seasonal molt.

They are particularly associated with budgerigars.

Possible signs include white, flaky or porous crusts around:

• Cere
• Nostrils
• Beak
• Eyes
• Legs

Advanced disease can lead to persistent structural changes.

Scaly-Leg Mites

Canaries and finches can also develop mite-related leg and toe changes.

Look for:

• Crusting
• Flaking
• Abnormally thickened scales
• Changes around toes

This appearance is very different from ordinary feather replacement.

Red Mites in Outdoor Aviaries

Red mites are more relevant to outdoor aviaries and nest-box environments than to many indoor pet birds.

They can hide in surrounding structures and feed on birds during periods of rest.

Possible signs include:

• Nighttime restlessness
• Weakness
• Anemia in severe infestations
• Problems in nestlings
• Tiny reddish spots in the environment

A Simple Night Check for Environmental Mites

When red mites are suspected in an aviary, environmental evidence can be helpful.

Inspect:

• Nest boxes
• Cracks
• Perch joints
• Cage corners
• Wooden structures

Environmental parasite management is often just as important as treating the bird itself.

Why Treating Only the Bird May Fail With Environmental Mites

Some parasites spend significant time away from the host.

This creates a cycle:

bird → environment → bird again.

Cleaning, environmental management and replacement of heavily contaminated porous materials may therefore be necessary.

Should You Automatically Use Ivermectin for Feather Loss?

No.

Ivermectin is an antiparasitic, and veterinarians may use it for selected susceptible mites and nematodes.

But it does not treat:

• Normal molt
• Behavioral plucking
• Poor nutrition
• PBFD
• Fungal feather disease
• Every cause of itching

Parasite treatment makes the most sense when parasite involvement is actually suspected or confirmed.

When Parasite Treatment Is Appropriate

An avian veterinarian may evaluate:

• Skin appearance
• Crusting
• Feather condition
• Housing type
• Exposure history
• Microscopic skin scrapings

before selecting a parasite-control strategy.

Poor Nutrition and Feather Loss

Nutrition is one of the most important—and often overlooked—causes of poor feather quality.

A bird may eat enough calories while still receiving an unbalanced nutrient profile.

Seed-heavy diets are particularly problematic because they can be deficient in important nutrients.

Protein and Feather Growth

Feathers are primarily structural protein.

Growing new plumage therefore requires adequate:

• Protein
• Essential amino acids
• Energy
• Vitamins
• Minerals

Poor nutrition can produce weak, dull or abnormal feathers.

Vitamin A and Feather Health

Vitamin A is important to normal epithelial tissue and overall avian health.

Poorly balanced seed-heavy diets can be deficient in vitamin A.

Deficiency may contribute to poor feather quality, abnormal skin and other health problems.

Should You Add Large Amounts of Vitamins During Molt?

No.

The goal is nutritional balance—not indiscriminate supplementation.

Too many overlapping supplements can create their own nutritional problems.

Review the complete diet rather than adding multiple products without understanding what the bird already receives.

Can Poor Nutrition Cause Feather Plucking?

Yes.

Poor feather and skin quality can produce discomfort.

Nutritional deficiency can also contribute to broader illness that influences feather-destructive behavior.

Diet assessment should therefore be part of a feather-plucking workup.

Skin Infections and Feather Loss

Bird skin can develop bacterial or fungal disease.

Skin inflammation can make a bird:

• Scratch
• Overpreen
• Chew feathers
• Damage skin

Secondary infection can also develop after repeated self-trauma.

Feather Follicle Infection

Feather follicles themselves may become inflamed or infected.

This can interfere with normal feather growth.

Persistent poor feather development from one specific region deserves closer examination.

What Are Feather Cysts?

A feather cyst forms when a developing feather cannot emerge normally from its follicle.

Instead, the feather grows beneath the skin and creates a lump.

Feather cysts can occur in multiple species but are particularly recognized in some canaries and certain parrots.

What Does a Feather Cyst Look Like?

Possible signs include:

• A firm skin lump
• A swelling associated with a feather follicle
• Abnormal local feather growth
• Repeated recurrence in the same area

Do not squeeze or cut a suspected feather cyst at home.

PBFD: When Abnormal Feather Loss Requires a Different Level of Investigation

Psittacine Beak and Feather Disease, commonly called PBFD, is caused by a circovirus.

It primarily affects parrots and related psittacine species.

Possible feather-related clues can include:

• Abnormal developing feathers
• Progressive feather loss
• Poor regrowth
• Abnormal pin feathers
• Feather loss in areas the bird cannot reach
• Loss of normal feather coloration in some birds

Which Birds Are Relevant to PBFD?

PBFD is especially important to consider in parrots such as:

• Cockatoos
• African greys
• Eclectus parrots
• Lovebirds
• Lorikeets
• Other susceptible psittacines

Not every bird with poor plumage has PBFD.

Testing is required for diagnosis.

Why Feather Loss on the Head Can Matter

Self-plucking usually affects areas reachable by the bird's own beak.

If the top of the head is losing feathers without a cage mate causing damage, a medical disorder deserves investigation.

PBFD is one possible differential diagnosis among others.

PBFD Does Not Mean Every Abnormal Feather Is Viral

Malformed feathers can occur for several reasons.

These may include:

• Follicular disease
• Trauma
• Nutrition
• Infection
• Viral disease

The pattern and diagnostic testing matter.

Internal Illness Can Affect Feathers

Feathers often reflect the health of the entire bird.

Internal disease can contribute indirectly to:

• Poor feather quality
• Delayed molt
• Abnormal regrowth
• Secondary feather plucking

Liver Disease and Feather Problems

Birds with liver disease may develop systemic changes that affect skin, feather quality or behavior.

Some birds with internal discomfort may also begin damaging feathers over the affected body region.

Kidney Disease and Feather Destructive Behavior

Kidney disease is another example of a medical problem that may be associated with discomfort and secondary feather-destructive behavior.

Feather loss accompanied by increased drinking, abnormal urates, weight loss or other systemic changes deserves a complete veterinary workup.

Giardia and Feather Problems in Cockatiels

Giardia is an intestinal protozoal parasite.

It has historically been associated with feather-destructive behavior in some cockatiels.

This does not mean every feather-picking cockatiel has Giardia.

Digestive signs and appropriate testing should guide the investigation.

Respiratory Disease Can Indirectly Affect Feather Condition

A chronically ill bird may spend less time grooming normally.

Illness can also alter:

• Appetite
• Nutrition
• Energy
• Preening behavior

Feather problems accompanied by sneezing, wheezing, nasal discharge or tail bobbing should therefore be investigated more broadly.

Why Body Weight Is Essential During Feather Loss

Feathers can hide major changes in body condition.

A gram scale can reveal whether a bird that appears merely “molty” is actually losing significant weight.

Track trends rather than one isolated reading.

Feather Loss Plus Appetite Loss Is Not a Normal Molt Pattern

A molting bird may occasionally be somewhat quieter.

But marked appetite reduction combined with progressive feather loss deserves investigation.

Feather Loss Plus Abnormal Droppings

This pattern may indicate that something systemic is happening.

Potential categories include:

• Digestive disease
• Parasites
• Liver disease
• Kidney disease
• Other systemic illness

Feather Loss Plus Severe Itching

Severe itching moves the investigation beyond simple molt.

Possible categories include:

• Skin inflammation
• Parasites
• Infection
• Environmental irritation
• Other dermatologic disease

Feather Loss Plus Bleeding

Bleeding requires prompt attention.

Possible causes include:

• Broken blood feather
• Self-trauma
• Cage injury
• Other bird trauma

Ongoing bleeding in a small bird can become significant quickly.

Budgie Losing Feathers in Fall

Budgies often show obvious pin feathers during active molt.

A healthy Autumn molt may include:

• Forehead pin feathers
• Loose body feathers
• Temporary untidiness
• Increased preening

But budgies are also particularly associated with scaly-face mites.

White or porous crusting around the cere, beak or legs is not a typical sign of ordinary molt.

Cockatiel Losing Feathers in Fall

Cockatiels may undergo noticeable seasonal feather replacement.

Because they naturally produce powder down, owners may notice:

• More feather dust
• More loose feathers
• Visible pin feathers

Cockatiels can also develop feather-destructive behavior for medical or behavioral reasons, so persistent bald areas deserve investigation.

Parrot Losing Feathers

Parrots such as African greys, cockatoos and macaws are particularly well known for feather-destructive behavior.

Potential contributing factors include:

• Medical disease
• Poor nutrition
• Boredom
• Stress
• Hormonal behavior
• Inappropriate environment

Do not assume a behavioral explanation until medical causes have been considered.

African Grey Feather Plucking

African greys are intelligent, sensitive birds that may develop feather-destructive behavior.

However, African greys are also among the parrot species in which viral feather disease deserves consideration when feather growth itself becomes abnormal.

Persistent abnormal feather loss should therefore be assessed medically.

Cockatoo Feather Plucking

Cockatoos are particularly recognized for severe feather-destructive behavior in some captive situations.

Contributors can include:

• Social attachment
• Hormonal behavior
• Boredom
• Stress
• Skin disease
• Poor nutrition

A complete behavioral and medical approach usually works better than focusing on one cause.

Canary Losing Feathers

Canaries can undergo an obvious seasonal molt and may temporarily sing less during feather replacement.

But canaries also deserve evaluation for:

• Scaly-leg mites
• Feather cysts
• Nutritional problems
• Other disease

when the pattern does not resemble normal molt.

Finch Losing Feathers

Finches are small birds, so subtle body-condition changes can become important quickly.

Monitor individual birds for:

• Weight loss
• Baldness
• Skin lesions
• Crusty legs
• Reduced activity

Pigeon Losing Feathers in Fall

Autumn feather replacement is particularly relevant in pigeons.

Racing and performance pigeons may be simultaneously recovering from:

• Training
• Racing
• Seasonal changes
• Feather replacement

Healthy molt should still produce normal new feathers.

Persistent poor regrowth, severe itching, weight loss or abnormal droppings deserves further evaluation.

Lovebird Feather Loss

Lovebirds may damage their own feathers or those of a cage mate.

Observe pair interactions carefully before assuming that an affected bird is self-plucking.

Can Fall Dry Air Cause Feather Problems?

Heating systems often lower indoor humidity.

Dry skin may increase discomfort and preening in some birds.

Appropriate bathing and suitable humidity can support normal skin comfort.

However, dry air alone should not be blamed for severe feather loss.

Bathing During Fall Molt

Many birds benefit from voluntary bathing or gentle misting.

Bathing supports:

• Normal preening
• Feather cleanliness
• Skin comfort
• Softening of mature pin-feather sheaths

Do not force a frightened bird to bathe.

Sleep and Feather Health

Normal light-dark rhythms matter to overall bird health.

Autumn may change household schedules, but birds still benefit from predictable periods of uninterrupted darkness and rest.

Environmental Enrichment for Birds That Overpreen

Healthy enrichment can include:

• Foraging opportunities
• Rotating toys
• Safe chewing materials
• Training sessions
• Appropriate social interaction
• Opportunities for normal movement

The goal is to give the bird healthy alternatives to repeatedly focusing on its own feathers.

Do Not Accidentally Reinforce Feather Plucking

If every plucking episode immediately creates dramatic attention from the owner, some birds may learn that feather-focused behavior changes human interaction.

Behavioral management should emphasize healthy activities and normal behavior while medical causes are investigated.

How an Avian Veterinarian Investigates Feather Loss

The diagnostic plan depends on the bird.

Possible steps may include:

• Detailed diet history
• Environmental history
• Physical examination
• Feather examination
• Skin examination
• Microscopic skin scraping
• Blood testing
• Biochemistry
• Viral testing
• Imaging
• Skin or feather-follicle biopsy
• Fecal testing

Why the Bird's History Matters So Much

Your veterinarian may ask:

• When did feather loss begin?
• Was it sudden or gradual?
• Is the bird actually seen pulling feathers?
• Has the household recently changed?
• What does the bird eat?
• How much sleep does it get?
• Is another bird present?
• Does it live indoors or outdoors?
• Are there any changes in appetite or droppings?

These details can be diagnostically valuable.

Take Photos of the Feather-Loss Pattern

Weekly photos can help show whether:

• The bald area is expanding
• Pin feathers are emerging
• Skin inflammation is improving
• Feathers are being damaged repeatedly

Consistency is more useful than obsessively checking every hour.

Save Some Shed Feathers

If the pattern is unusual, keeping several representative feathers can help demonstrate whether they appear:

• Naturally shed
• Broken
• Chewed
• Malformed

Bring them to the veterinary appointment if useful.

A Home Feather-Loss Investigation Checklist

Before deciding that the bird is “just molting,” check:

1. Feather integrity: Are fallen feathers whole or damaged?

2. Regrowth: Are healthy new pin feathers appearing?

3. Pattern: Is feather loss gradual or creating obvious bald areas?

4. Reachability: Can the bird physically reach the affected area?

5. Skin: Is there redness, crusting, flaking or injury?

6. Itching: Is scratching mild or severe?

7. Weight: Is body weight stable?

8. Appetite: Is the bird eating normally?

9. Droppings: Have they changed?

10. Behavior: Is the bird simply molting or becoming generally unwell?

Frequently Asked Questions About Bird Feather Loss in Fall

Why is my bird losing feathers in fall?

Seasonal molt is a common possibility, but mites, feather-destructive behavior, nutrition, skin disease and systemic illness can also cause feather loss.

How do I know whether my bird is molting?

Normal molt is generally gradual, naturally shed feathers tend to remain relatively intact, and healthy new pin feathers appear as replacement plumage grows.

Should birds get bald patches when molting?

Large or rapidly expanding bald patches are not the classic pattern of an orderly healthy molt and deserve closer examination.

Why does my bird have pin feathers?

Pin feathers are developing replacement feathers growing inside protective keratin sheaths.

Why are my bird's pin feathers abnormal?

Persistent malformed or poorly developing feathers may warrant evaluation for nutritional, follicular, infectious or viral problems.

How can I tell molt from plucking?

Molted feathers are generally shed naturally and replaced. Plucked or chewed feathers may be shredded, broken, shortened or repeatedly damaged.

How can I tell mites from molting?

Mite disease may produce signs such as crusting, abnormal scales, severe environmental exposure patterns or nighttime restlessness depending on the parasite. Normal molt produces feather replacement rather than parasite-specific skin changes.

Do mites commonly cause feather loss in indoor pet birds?

Not as commonly as many owners assume. Feather mites are relatively uncommon in many indoor pet birds.

What do scaly-face mites look like?

They can produce flaky, pale or porous crusts around the cere, beak, nostrils, eyes or legs, especially in budgies.

Can red mites affect birds?

Yes. Red mites are particularly relevant in outdoor aviaries and nest-box environments.

Should I use ivermectin every time my bird loses feathers?

No. Ivermectin is an antiparasitic and will not correct normal molt, behavioral plucking, nutritional deficiency or many other causes of feather loss.

Why is my bird chewing its feathers?

Possible causes include behavioral stress, boredom, hormonal activity, skin irritation, medical disease or poor nutrition.

Why does my bird pluck only its chest?

Localized plucking can have behavioral or medical causes. Pain or disease beneath a particular area can sometimes contribute to localized feather damage.

Why is my bird losing feathers from its head?

The bird cannot easily self-pluck the top of its head, so another bird, disease, abnormal feather growth or other medical causes should be considered.

Can another bird pull out my bird's feathers?

Yes. Cage-mate barbering can produce feather damage that resembles self-plucking.

Can stress make birds pluck?

Yes. Stress can contribute to feather-destructive behavior, although medical causes should be investigated as well.

Can boredom cause feather plucking?

Yes. Under-stimulation can contribute to repetitive feather-focused behavior in intelligent companion birds.

Can hormones cause feather plucking?

Hormonal and reproductive behavior can contribute in some birds.

Can poor diet cause feather loss?

Poor nutrition can interfere with normal skin and feather development and may contribute to feather-destructive behavior.

Can a seed-only diet cause bad feathers?

Seed-heavy diets can be nutritionally unbalanced and may be deficient in nutrients important to normal skin, feathers and immune function.

Does a molting bird need more protein?

Feather production requires adequate protein and amino acids, but additional supplementation is not automatically necessary when the bird already eats a complete balanced diet.

Can vitamin A deficiency affect feathers?

Yes. Vitamin A deficiency can contribute to poor epithelial health and poor feather quality, particularly in birds consuming nutritionally incomplete diets.

Can skin infection make a bird pull feathers?

Yes. Bacterial, fungal or yeast-related skin disease can create discomfort and secondary feather damage.

What is a feather cyst?

A feather cyst forms when a developing feather fails to emerge normally and grows beneath the skin.

Should I pop a feather cyst?

No. Suspected feather cysts should be examined professionally rather than cut or squeezed at home.

What is PBFD?

Psittacine Beak and Feather Disease is a circovirus infection of parrots that can cause abnormal feather growth, feather loss and other health problems.

Does every parrot with feather loss have PBFD?

No. Numerous nutritional, behavioral, environmental and medical problems can cause feather loss. PBFD requires appropriate diagnostic testing.

Can liver disease affect feathers?

Yes. Internal organ disease can alter feather quality and may also contribute indirectly to feather-destructive behavior.

Can kidney disease cause plucking?

Medical discomfort associated with internal disease can contribute to abnormal feather-focused behavior in some birds.

Can Giardia cause feather picking?

Giardia has been associated with feather-destructive behavior in some cockatiels, but it is not the explanation for every plucking bird.

Can dry air cause feather plucking?

Dry skin may increase discomfort or preening, but severe plucking deserves a broader medical and behavioral evaluation.

Does bathing help during molt?

Normal voluntary bathing can support preening, skin comfort and feather cleanliness.

Should I weigh my bird during feather loss?

Yes. Weight trends can help identify systemic illness that plumage may visually conceal.

When should I see an avian veterinarian?

Seek evaluation for bald areas, abnormal pin feathers, severe itching, wounds, bleeding, poor regrowth, weight loss, appetite changes, weakness or other signs of illness.

The Fall Feather-Loss Decision Tree

Feathers are falling but remain whole?
Look for healthy pin-feather replacement and otherwise normal health. Seasonal molt becomes more likely.

Feathers look chewed or shredded?
Consider feather-destructive behavior, cage-mate barbering, irritation or medical disease.

Crusts around beak, cere or legs?
Investigate scaly-face or scaly-leg mites.

Bird is restless mainly at night in an outdoor aviary?
Investigate environmental mites.

Bird has bald areas it cannot reach?
Investigate another bird's behavior or medical feather disease.

New feathers grow abnormally?
Investigate nutrition, follicular disease, infection and viral causes.

Feather loss is accompanied by weight loss or illness?
Treat the situation as a whole-bird medical problem rather than a cosmetic feather issue.

The Five Questions That Matter Most

Is the bird replacing feathers?

Are the feathers whole or damaged?

Can the bird physically reach the affected area?

Does the skin look healthy?

Is the rest of the bird healthy?

Those five questions can often distinguish a reassuring Autumn molt from a problem that deserves deeper investigation.

Important bird-health notice: Feather loss has many possible causes. A slow, gradual molt with intact shed feathers and healthy replacement pin feathers can be normal, while bald patches, chewed or broken feathers, severe itching, abnormal crusting, poor feather regrowth, malformed feathers, bleeding, substantial weight loss, appetite loss or other signs of illness deserve further evaluation. Mites are not the cause of every feather problem, and antiparasitic products should not be used simply because a bird is losing feathers. Persistent or abnormal feather loss should be evaluated by an avian veterinarian.
