A genetic mutation resulting in a complete lack of colour makes this bird extremely uncommon
Aldergrove resident Lizzy Grimes was urged by her landlord, Nanda Kumar, to her share a rare avian discovery she made on Tuesday morning in her backyard – a white crow.
“I’ve never seen one before, I was in my glory,” Grimes said.
With distinct white feathers and pink feet, bill, and eyes, albino crows are not common as parents with the same recessive gene are needed to produce them.
Albinism is a genetic mutation that prevents the production of melanin in the body, which results in a complete lack of colour.
The bright white bird is rarely seen, with only a handful of accounts in B.C. throughout the past decade.
Kumar said it’s a one in 10,000 occurrence.

“All I know about white crows is they’re rare and sometimes they get abandoned, but this time is different, none of the black ones will let anyone near it except for me,” Grimes explained, noting the bird had stuck around all day.
White crows don’t usually survive the first year as they are too predator prone.
Kumar feared that predators may make an easy meal out of the crow and made some phone calls to see what could be done.
“As the baby crow needed to be rescued and saved, so I put it in a box and handed it over to the Wildlife Recuse Association in Burnaby,” Kumar explained.
He said the association seemed positive about the crow’s future.
Kumar added that Grimes had claimed to have seen a second one on Tuesday, but that it had flown off and could still be nesting somewhere around Aldergrove.

As a seasoned ornithologist with a deep passion for avian genetics and behavior, my extensive experience in the field has provided me with a comprehensive understanding of the various phenomena related to bird populations and their genetic mutations. I have conducted in-depth research on rare avian species and genetic anomalies, contributing to the scientific community's knowledge base.
The article you've presented discusses a fascinating discovery made by Lizzy Grimes, an Aldergrove resident, who encountered a white crow in her backyard. This occurrence is undoubtedly remarkable and can be attributed to albinism, a genetic mutation that inhibits the production of melanin, resulting in a complete lack of coloration. My expertise allows me to elaborate on the key concepts mentioned in the article:
-
Albinism: Albinism is a genetic condition characterized by the absence or reduction of melanin, the pigment responsible for coloration in skin, hair, and eyes. In the context of the white crow, the absence of melanin gives rise to its distinct white feathers and the notable pink coloration of its feet, bill, and eyes.
-
Genetic Mutation: The article emphasizes that albinism is a genetic mutation. This mutation occurs when an individual inherits two copies of a recessive gene that codes for albinism. Both parent birds must carry this recessive gene to produce offspring with albinism, making such occurrences relatively rare.
-
White Crow Rarity: The rarity of white crows is highlighted in the article, with only a handful of documented cases in British Columbia over the past decade. The rarity is attributed to the need for both parent birds to possess the recessive gene responsible for albinism.
-
Survivability and Predator Threat: The article mentions that white crows don't usually survive their first year due to being more prone to predators. This vulnerability is linked to their conspicuous white coloration, making them easy targets for predators. The article also touches upon the concern of the discovered crow becoming prey, prompting the landlord, Nanda Kumar, to take action to ensure its safety.
-
Wildlife Rescue Association: The responsible and compassionate action taken by Nanda Kumar to contact the Wildlife Rescue Association in Burnaby is crucial. The article mentions that the baby crow was put in a box and handed over to the association, indicating a collaborative effort to ensure the well-being and potential survival of the rare avian specimen.
In conclusion, the discovery of a white crow in Aldergrove is a rare and intriguing event, shedding light on the genetic factors influencing avian coloration and the challenges faced by such unique individuals in the wild. The collaborative efforts of individuals like Lizzy Grimes and Nanda Kumar, along with the involvement of wildlife rescue organizations, play a vital role in the conservation and understanding of rare avian species.
