Hummingbirds are unique in that their feathers boast two extraordinary properties simultaneously: superhydrophobicity and iridescence. These properties are hypothesized to be linked to the intricate structure of hummingbird feathers, characterized by microscopic barbes and barbules. We propose to reveal the geometry of the hummingbirdÂ’s hierarchical feather structure and how it leads to combined superhydrophobicity and iridescence. Using this information, we will also build an experimental model system of the feather structure using glass capillaries to precisely link the splashing characteristics to the angle of the barbules.

I am participating in this SuperUROP because it allows me to combine my two favorite things: engineering and ornithology. My fascination with birds and their intricate mechanisms dates back to my high school years, where I developed a deep curiosity about their innerworkings. I am excited to apply my background in mechanical engineering and ornithology to reveal the mechanisms that make hummingbird feathers unique.
