Anna’s Hummingbird Changing Colors: Explanation!

Anna’s Hummingbird is known for its remarkable ability to change colors, a phenomenon that largely results from the iridescence in their feathers rather than pigment.

The shifting colors in the feathers of Anna’s Hummingbird can be seen when sunlight hits their plumage at different angles, creating a dazzling display of greens, blues, and even fiery reds or pinks on the males, particularly on their gorgets (throat feathers).

The color-changing effect in Anna’s Hummingbird is due to the microscopic structure of the feathers.

Unlike pigment-based colors, which remain constant regardless of the viewing angle, iridescent colors are created by the microscopic arrangement of feather barbules.

When light strikes these structures, it is refracted and split into various colors, much like a prism. The specific angle and quality of the light, as well as the viewer’s perspective, will determine which colors are seen.

In Anna’s Hummingbird, males often display more pronounced iridescence than females, using their dynamic coloration to attract mates and deter rivals.

Here are key points about Anna’s Hummingbird color change:
