White crows, also known as “albino crows” or “leucistic crows,” are a rare and unique sight in the bird world. They are a result of a genetic mutation or a lack of melanin production in their feathers, causing them to have all white or partially white plumage. While they may look different from their black-feathered counterparts, they are still the same species as regular crows.
The cause of white feathers in crows can be attributed to two main factors: a genetic mutation or a lack of melanin production. In the case of a genetic mutation, a crow may have a gene that causes it to have white feathers. This mutation can be passed down to offspring, making it more common in certain populations. Alternatively, a lack of melanin production can also cause white feathers in crows, which is known as leucism. This condition affects the pigmentation of the feathers, resulting in white or partially white plumage.
There are three main types of white crows:
- partially white crows
- leucistic crows
- albino crows
Partially white crows have a mix of black and white feathers, while leucistic crows have mostly white feathers with some patches of black. Albino crows, on the other hand, have completely white feathers and pink or red eyes due to the absence of melanin.
Aside from their white feathers, white crows have the same characteristics and behaviors as black crows. They are intelligent, social, and highly adaptable birds. However, their unique appearance may make them stand out from the crowd, potentially making them more vulnerable to predators. Despite this, there is no significant advantage or disadvantage for white crows compared to black crows.
White crows are considered rare, with only a small percentage of crows having white feathers. However, their sightings are becoming more common due to increased urbanization and exposure to pollutants. In some cultures, white crows hold significant cultural and spiritual significance. They are often seen as harbingers of good or bad omens and have been represented in various mythologies and spiritual beliefs.
What Are White Crows?
White crows, also known as albino crows, are a rare genetic variation of the common black crow. Unlike albinism, which causes a complete lack of pigmentation, white crows have white feathers due to a genetic condition called leucism. This condition results in a partial loss of pigmentation, giving the crows white or pale-colored feathers while maintaining their normal eye and bill coloration. Due to their unique appearance, white crows have sparked curiosity and fascination among ornithologists and bird enthusiasts, leading to further study into their genetic makeup and behavior.
What Causes White Feathers in Crows?
White feathers in crows can be caused by a genetic mutation called leucism, which reduces the pigmentation in the bird’s feathers. This condition is different from albinism, where the bird lacks all pigment. Leucism can result in patches or fully white plumage in crows. Other factors such as age, diet, and environmental stressors may also contribute to the development of white feathers in crows. If you happen to spot a crow with white feathers, it is best to observe from a distance to avoid causing any stress to the bird.
Is It a Genetic Mutation?
Yes, the presence of white feathers in crows is indeed a result of a genetic mutation. This mutation is known as leucism, where pigment cells do not properly migrate during development. As a result, the feathers may have a partial loss of pigmentation, giving them a white appearance. While this mutation is uncommon, it does occur in the crow population. To delve deeper into this topic, further research on leucism and its effects on crow populations may be beneficial.
Is It a Lack of Melanin Production?
Yes, the lack of melanin production leads to white feathers in crows. Melanin is responsible for pigmentation in feathers, and the absence or reduced production of melanin results in white plumage. This condition, known as leucism, affects the color of the feathers but not the bird’s eyes or beak. Interestingly, leucistic crows are not albinos, as their eyes and beak retain their natural color.
What Are the Different Types of White Crows?
While crows are typically known for their black feathers, there are actually several types of white crows that exist in the wild. These unique birds can have varying levels of white coloring, from just a few feathers to their entire body. In this section, we will discuss the different types of white crows, including partially white crows, leucistic crows, and albino crows. Each type has its own distinct characteristics and genetic makeup, making them fascinating to study and observe.
Partially White Crows
Partially White Crows, also known as pied crows, have a unique coloration with a combination of white and black feathers. This distinctive plumage is a result of genetic variations, resulting in sections of white feathers among their typical black plumage. These crows are of great interest to researchers and bird enthusiasts due to their rare and captivating appearance.
Leucistic Crows
Leucistic crows, often mistaken for albino crows, possess partial loss of pigmentation, leading to white or pale coloration. These distinct birds demonstrate different behaviors compared to black crows and may encounter difficulties due to their heightened visibility to predators. However, leucistic crows hold cultural importance in various mythologies and are viewed as both uncommon and mystical creatures.
In Japanese mythology, these crows, known as yatagarasu, are revered as sacred and represent divine intervention.
Albino Crows
Albino crows are a rare and unique sight, with their all-white feathers, pink eyes, and lack of melanin. This genetic mutation affects their ability to blend in with their surroundings, potentially making them more susceptible to predators. In certain cultures, albino crows are seen as symbols of good luck, while in others, they hold a sense of mystery and even foreboding.
Fun fact: In some Native American cultures, albino crows are believed to carry messages from the divine and are held in high regard as sacred creatures.
What Are the Characteristics of White Crows?
White crows are incredibly rare and often hold symbolic significance. They are typically the same species as black crows and may have genetic conditions causing their white plumage.

Frequently Asked Questions
What causes crows to have white feathers?
Crows can have white feathers for several reasons, including malnutrition (commonly known as “McDonald’s disease”), genetic conditions like leucism and albinism, and white pieces on feathers during molting. These factors can result in poor feather condition and color abnormalities in crows.
How can “McDonald’s disease” affect crows?
“McDonald’s disease” or malnutrition is a common cause of white feathers in crows. This is due to a poor diet, often consisting of white bread or french fries, which do not provide enough nutrition for the birds. This can lead to poor feather condition and make them more vulnerable to predators.
Can genetic conditions also cause white feathers in crows?
Yes, leucism and albinism are genetic conditions that can also cause white feathers in crows. In some cases, this may be due to old age rather than a genetic problem. More research is needed in this area to fully understand the genetic causes of white feathers in crows.
How can you tell the difference between “McDonald’s disease” and genetic causes of white feathers in crows?
The condition of the feathers can help differentiate between “McDonald’s disease” and genetic causes. In “McDonald’s disease,” the feathers will be in poor condition, while in genetic causes, the feathers will be in good condition but lack color. In cases of albinism, the crow may turn completely white or a caramel color.
What should I do if I see a crow with albinism?
If you see a crow with albinism, it is important to contact a corvid-friendly rehabber. Albinism is very rare and can be detrimental to the bird’s survival as they may not receive the necessary help they need.
Is it normal to see white pieces on crow feathers?
Yes, white pieces or parts seen on crow feathers during the molting process are normal. These pieces are made of keratin and will eventually peel off, similar to dandruff. This is a natural process and does not indicate any health issues for the crow.
