Digital Velocimetry Exposes Hummingbird Flight

Annie L. Fischer

Hummingbirds are fascinating to watch because, unlike other birds, they can hover in one spot for periods of time. The birds have been likened to insects in the way they flap their wings, but researchers from Oregon State University in Corvallis, the University of Portland and George Fox University in Newberg, all in Oregon, have dispelled this notion using digital particle imaging velocimetry to measure the wake of hummingbird flight. Researchers have used digital particle imaging velocimetry to study hummingbird flight. They placed the hovering birds in a wind tunnel seeded with droplets...Read full article
