Video: el increíble y bello vuelo del colibrí cuando toma agua

NatGeo nos muestra esta joya para evidenciar un momento único.

Un video de NatGeo muestra de manera precisa, en cámara lenta, el aleteo de un colibrí mientras intenta tomar agua al vuelo.

El registro fue captada en un túnel de viento a 26 millas por hora -casi 42 km p/h-. Para poder filmarlo, los realizadores comienzan grabando a 2000 cuadros por segundo al inicio, pero luego lo terminan haciendo en 3000 cuadros por segundo. Además, usaron máquinas para generar la niebla alrededor del pájaro para visualizar el aire y el vuelo.  

Video by @anandavarma / An Anna's hummingbird flies in a wind tunnel blowing at 26 miles per hour. These birds may be small, but they are much more powerful than you would think! This video was made possible by a storytelling grant from the National Geographic Society and became part of my hummingbird story for National Geographic Magazine. The focus of the story was on what tools scientists use to study these amazing birds. This video starts at 2000 frames per second and ends at 3000 frames per second. That means by the end, it is playing 100 times slower than what your naked eye would see. I modified an industrial humidifier to create a make-shift fog machine so that the air movement in the wind tunnel would be visible. Scientists use fog machines to visualize the air flow around hummingbird wings and wind tunnels to measure their flight performance. | These images are being shared in celebration of the 2018 National Geographic Explorers Festival, which brings together innovative scientists, conservationists, explorers, and storytellers from around the world to share their discoveries, insights, and solutions for creating a more sustainable future. To showcase the work of this community, @Cara_Santa_Maria —an award-winning science journalist, the creator of the popular podcast “Talk Nerdy,” and a correspondent on National Geographic’s Explorer television program—has selected six images from photographers who are also National Geographic Explorers.
