Swans, specifically mute swans, undergo a fascinating transformation in their feathers as they mature. The color change that occurs in swans is not related to their sex but rather a genetic trait. When swans hatch, their coloration can vary, with some individuals being gray and others being white. This initial color does not remain the same as they grow older.
Gray cygnets, or baby swans, gradually transition to a brownish color as they approach their first winter. This change in color is a natural progression and is part of their development. It’s quite interesting to observe this transformation, as the transition from gray to brown can occur subtly over time.
On the other hand, white cygnets retain their white color as they grow. They do not undergo the same color change as the gray cygnets. This variation in coloration among swans adds to the diversity and beauty of these magnificent birds.
It’s important to note that this color change is specific to mute swans, as other swan species may have different color patterns or no color change at all. Mute swans, as their name suggests, are not known for being very vocal compared to other swan species. While they can still make sounds, their vocalizations are typically less frequent and less pronounced.
In my personal experience observing swans, I have witnessed the gradual color change of gray cygnets into a brownish hue. It is a remarkable sight to see them grow and develop their adult plumage. The transition from gray to brown is a natural process that occurs as they mature.
To summarize, swans, specifically mute swans, do turn brown, but this color change is not related to their sex. Gray cygnets gradually transition to a brownish color by their first winter, while white cygnets retain their white coloration. The color change in swans is a genetic trait and adds to the uniqueness and beauty of these birds. Mute swans are also known for their relatively quiet nature compared to other swan species.
