Cardinals are known for their bright red plumage, but sometimes cardinals can suffer from partial or complete baldness. There are a few potential reasons why a cardinal may lose its feathers:
Molting
Molting is a natural process where birds shed old feathers to make way for new growth. Cardinals molt once a year, usually after breeding season. During the molt, they can look scruffy, with missing patches of feathers. This is normal and the feathers will grow back within a few weeks.
Stress
Stress can cause cardinals to pluck out their own feathers. This self-mutilation is called feather-plucking or pterotillomania. Common stressors include:
| Stressor | Description |
|---|---|
| Lack of food | Not having adequate access to food sources causes nutritional stress. |
| Nesting issues | Problems with nest location or nesting materials can cause anxiety. |
| Diseases | Illnesses like avian mites or infections can cause discomfort. |
| Predators | Fear of predators like cats or hawks leads to nervous behavior. |
| Human activity | Excessive noise, chasing, or other disruptions by people. |
Removing the source of stress, whether natural or human-created, can help stop baldness from feather-plucking. Providing proper food, nesting sites, and cover from predators reduces natural stressors. Avoiding excessive interactions with cardinals reduces human-related stress.
Nutritional deficiency
Cardinals with restricted diets may lack adequate protein, oils, carotenoids, or vitamins that contribute to vibrant plumage. Supplementing food sources with bird feeders providing nutritious commercial seed mixes or suet cakes helps provide a balanced diet.
Disease or health issues
Skin infections, mites, lice, fungal infections, or metabolic diseases can cause feather loss in cardinals. Consulting an avian veterinarian helps diagnose and treat any underlying health issues. Proper diagnosis requires examining the bird and skin/feather samples under a microscope.
Age
Older cardinals often show fading of their bright red feathers. Pigment loss causes feathers to appear more orange or yellow. Plumage may also look ragged or thin. However, age alone does not cause complete baldness – an elderly bird with patchy plumage still has underlying health issues.
Physical trauma
Injuries, accidents, or predator attacks may damage the follicle anchoring cardinal feathers. Plucking, biting, crashes, or metabolic shock after trauma halt feather growth. Cardinals may temporarily lose plumage around wounds.
What to do if your cardinal is bald
If your backyard cardinal is suffering from significant baldness, take these steps:
Check for injuries
Look for cuts, punctures, or scabs from physical trauma. Carefully catch the bird with a towel and take it into a warm, quiet space for closer inspection. Covering the head calms birds. Handle with extreme care and call an avian vet if you find wounds.
Evaluate diet
Supplement natural food sources with bird feeders. Offer sunflower seeds, nyjer thistle, safflower seeds, raisins, unsalted nuts, dried mealworms, and suet. Provide fresh water daily. Consider adding vitamin drops to their water a few times per week.
Reduce stress
Monitor for neighborhood cats, children harassing birds, loud vehicles, or other disruptions within 50 feet of feeders. Place feeders near trees or shrubs to provide quick escape cover. Consider moving feeders to a quieter location.
Add shelter
Birds need brush piles, evergreen trees, or nest boxes to retreat from bad weather and predators. Place these bird shelters near feeding areas.
Try baths
Bathing helps birds maintain healthy feathers and skin. Use a shallow dish, add fresh water daily, and sprinkle seed around the edges to encourage bathing.
Isolate sick birds
Separate sick birds from the flock to prevent disease spread. Set up a wire cage or plastic bin with air holes in a warm, draft-free area. Line the bottom with paper towels. Wear gloves when handling isolated birds.
Seek vet care
For complete baldness, major feather damage, or signs of illness, consult an avian veterinarian. Proper treatment depends on the underlying cause. Vets can prescribe medications, deliver nutrients by injection, or fit the bird with a collar to prevent self-mutilation.
With supportive care, most bald cardinals can regrow stunning plumage. Persistence pays off when nursing a bird back to health. The return of a cardinal’s vibrant red feathers represents the success of your rehabilitation efforts. A once-bald cardinal svourishing in your yard symbolizes the resilience of nature.
What causes baldness in cardinals?
There are a number of reasons why cardinals lose their feathers:
Natural molting
– Cardinals molt once per year after breeding season
– Shedding old feathers makes way for new growth
– Looks like missing patches and scruffy appearance
– Feathers regrow within weeks
Stress leading to over-preening
– Self-inflicted feather loss is called pterotillomania
– Stressors include lack of food, predators, human activity, diseases, nesting issues
– Remove the source of stress to prevent bald spots from over-preening
Nutritional deficiencies
– Need adequate protein, oils, carotenoids, vitamins for healthy plumage
– Lack of nutrients causes dull, thin, or lack of feathers
– Use seed feeders to supplement natural food sources
Infections and illnesses
– Skin infections, mites, lice, fungal infections can cause feather loss
– Metabolic or chronic diseases may also lead to baldness
– An avian vet can diagnose and treat any health issues
Age-related changes
– Older cardinals often show fading of bright red feathers
– Plumage appears more orange, yellow, ragged, or thin
– Age alone does not cause complete baldness
Physical trauma
– Injuries, predator attacks, accidents damage feather follicles
– Plucking, biting, shock halts feather regrowth
– Temporary baldness around wounds
Diagnosing the cause of baldness
There are a few techniques available to diagnose what underlying issue is causing your cardinal’s baldness:
Physical examination
Gently inspect the bird’s skin and feathers for evidence of trauma, parasites, infection or abnormalities. Use gloves and proper restraint techniques to avoid injury during handling.
Microscopic analysis
Pluck a few damaged feathers and brush the bird’s skin for skin/feather samples. Examine under a microscope for mites, lice or fungal hyphae. Compare results to normal feather and skin slides.
Complete blood count
A veterinarian can collect a blood sample from a vein or nail clip to check for anemia, inflammation, circulating parasites, or other irregularities that may be causing feather issues.
Nutritional testing
Laboratories can analyze plasma samples for protein levels, vitamin and mineral deficiencies, liver enzymes, and metabolites that indicate nutritional disorders.
Bacterial culture
Swab the bare skin and submit samples to a lab for bacterial culturing. Identify pathogenic bacteria like staphylococcus or pseudomonas species that may be provoking skin irritation and feather picking/loss.
Biopsy
Surgically removing a portion of affected skin for pathological testing lets veterinary dermatologists determine causes of feather follicle disruption. Biopsies differentiate infections, cancers, immune diseases, etc.
Radiographs
Taking x-rays can identify fractures, airsac disease, bone infection, or masses impinging on feather follicles. Radiography also shows ingestion of foreign bodies that could be leeching toxins internally.
Treatment options for bald cardinals
If the underlying cause of your cardinal’s baldness is identified, here are some treatment options to restore its red plumage:
Nutritional support
– Correct dietary deficiencies with vet-formulated bird food
– Injectable or oral vitamin supplements
– Ensure adequate essential fatty acids
Antibiotics
– Bacterial infections require appropriate antibiotics
– Common medications for birds include enrofloxacin, cephalexin, azithromycin
Antifungals
– For fungal infections, give oral itraconazole or apply miconazole cream
Antiparasitics
– Ivermectin eliminates mites and lice
– Spinosad for difficult cases
Steroids/immunosuppressants
– Autoimmune or inflammatory issues may need steroids
– Cyclosporine, azathioprine for immune regulation
Behavior modification
– Prevent self-mutilation feather plucking with collar
– Modify environment to reduce stress
Surgery
– Drainage, debridement for infected skin
– Biopsy removal
– Tumor removal
With the right treatment plan tailored to the specific diagnosis, bald cardinals can fully recover their vibrant plumage.

Frequently asked questions
Why did my cardinal go from red to yellow?
Fading of red plumage to a more yellow or orange hue is often a sign of aging in cardinals. Pigment loss causes their bright color to dull over time. However, serious illness, poor diet, or extreme stress can also cause similar feather color changes in younger cardinals.
Do cardinals molt all their feathers at once?
No, cardinal molting is a gradual process. They lose a few feathers at a time, starting on the head and working down the body over several weeks in late summer. Symmetrical molting helps retain the ability to fly. Sudden loss of all feathers could be due to a shock event or disorder.
Should I help an injured bald cardinal?
Injured bald cardinals often require rehabilitation assistance. Gently contain the bird and call a wildlife rehabilitator immediately. Do not try feeding it. With expert help, many injured cardinals recover to be rereleased into the wild.
What to feed a bald cardinal?
Offer a commercial seed mix formulated for songbirds. Fortified seeds give essential nutrition for feather regrowth. Also provide suet cakes for extra fat and calories. Fresh water with vitamin drops supports recovery. Avoid bread or junk food.
How long does it take feathers to grow back?
Cardinal feathers regrow over several weeks, starting as pins around the bare follicle. Small body feathers fill in first, followed by larger wing and tail feathers. Full replacement of all flight and contour feathers can take 1-2 months. Some pigment loss may persist.
