TL;DR
A rare leucistic loon chick was photographed in Montana, with images showcasing its distinctive white plumage. The sighting is significant due to the rarity of leucism in loons, estimated at 1 in 30,000.
A leucistic loon chick was photographed in Montana, marking a rare sighting of a bird with partial loss of pigmentation, a condition known as leucism. The photos, taken by wildlife photographer Tony Gangemi, highlight the rarity of such an occurrence and underscore the significance for bird conservation and observation enthusiasts.
In May 2025, Montana-based photographer Tony Gangemi captured images of a leucistic loon chick on a small lake in Northwest Montana. The chick displayed a predominantly white plumage, a result of leucism, a genetic condition causing partial pigmentation loss. This condition affects approximately one in every 30,000 loons, making the sighting exceptionally rare.
Gangemi described the experience as a once-in-a-lifetime event, noting that he first spotted the white loonlet among a family of loons during his early morning birdwatching session. The adult loons and their chick, which was about one week old at the time, were observed during their nesting period, with the white chick standing out due to its unusual coloration.
Why It Matters
This sighting is significant because it provides rare visual documentation of leucism in loons, a condition seldom seen in the wild. Such occurrences can offer insights into genetic diversity and health within bird populations. For birdwatchers and conservationists, the sighting underscores the importance of habitat preservation and ongoing monitoring of loon populations, which face threats from predators and environmental changes.

Background
Loons are iconic waterbirds known for their haunting calls and striking black-and-white adult plumage. They migrate seasonally through North America, with Montana serving as a key stopover point during their migration. Prior to this sighting, leucism in loons was estimated to occur at a rate of approximately 1 in 30,000, making such observations exceedingly rare. The sighting by Gangemi in 2025 adds to the limited documented cases and highlights ongoing interest in loon conservation.
“This was a once-in-a-lifetime sighting. Seeing a leucistic loon chick in the wild is incredibly rare, and capturing its image was a profound moment for me as a photographer.”
— Tony Gangemi
“Leucism in loons is extremely uncommon, and such sightings can help us better understand genetic variation and potential impacts on survival.”

What Remains Unclear
It is not yet clear how many leucistic loons are currently present in the wild or whether this condition affects their survival and reproduction rates. Further observation and research are needed to assess the long-term implications of leucism in loon populations.

Key Questions
What is leucism, and how does it differ from albinism?
Leucism is a genetic condition causing partial loss of pigmentation, resulting in white or pale patches on the bird’s plumage, but unlike albinism, it does not affect eye color or melanin production in the eyes.
How rare are leucistic loons in the wild?
Leucism in loons is estimated to occur in about 1 in 30,000 individuals, making sightings like this exceptionally uncommon.
Could leucism impact the survival of the loon chick?
It is currently unclear whether leucism affects the chick’s ability to survive, as further research is needed to understand potential impacts on camouflage, predator avoidance, or health.
Are there other known cases of leucistic loons?
While rare, there have been a few documented cases of leucistic loons in North America, but sightings remain infrequent and highly valued by birdwatchers and scientists alike.
