Colors in Motion: The Beauty and Biology of Hummingbirds
Hummingbirds are known for their brilliant iridescent feathers. Their colors, ranging from vibrant greens to fiery reds and blues, are not due to pigments
The iridescence seen in hummingbirds comes from microscopic platelets in their feathers made of layers of nanostructures.
Each hummingbird feather has microscopic layers that manipulate light, similar to how oil on water creates a rainbow effect
This is particularly important for species with bright, shifting colors like the Ruby-throated Hummingbird or the Violet-crowned Hummingbird.
The vibrant colors of hummingbirds, particularly the throat (or "gorget") area, are used for communication.
Male hummingbirds often display these bright, iridescent colors during courtship rituals to attract mates or establish dominance over territory.
Beyond color, hummingbird feathers are designed for rapid, agile flight. Their wing feathers are structured to provide maximum lift and maneuverability
