Can Bluebirds See The Colour Blue
The color blue that we see on a bird is created by the way light waves interact with the feathers and their arrangement of protein molecules, called keratin. In other words, blue is a structural color. Different keratin structures reflect light in subtly different ways to produce different shades of what our eyes perceive as the color blue.
Many species use this color to attract mates or signal their dominance in a particular area. For example, male blue jays have vibrant blue feathers that they display during courtship rituals, while female bluebirds prefer males with brighter blue plumage. Moreover, some birds also use the color blue for camouflage and protection from predators.

The size of the nanostructure matches that of the wavelength of blue light. So, while all of the other colors pass through the feather, the blue does not. It is reflected, so you see blue.
This is why ground up feathers turn brown. Once the nanostructures are destroyed, you see the bird's true colors. 30 Amazing bluebird facts There is so much more to these little bluebirds than the eye sees.

The blue color seen on birds is often structural, created by how light interacts with feather structures rather than by pigments, allowing for unique visual signals. For example, female birds may prefer mates that reflect more UV light, signaling better health or fitness. Beyond social interactions, blue and UV vision aid foraging and food.
