The National Geographic Channel in conjunction with Clark lab at US Riverside, Dudley lab at UC Berkeley, have posted a video that shows the process of capturing hummingbirds in flight, feeding, and doing acrobatics all in glorious 4k at 2000fps. It is probably the most scientifically worthy portrayal of hummingbirds in flight ever to be documented.
The intricacies of flight, hovering and coping with the environmental elements that hummingbirds have to fend off and how they accomplish it are now being deciphered with the help of 4k Phantom Flex cameras in great detail mainly shot by naturalist filmmaker Anand Varma. This is all part of a recent National Geographic story on hummingbirds here!
