 A slow-motion video has shown how the hummingbirds deal with rain when they are flying.To remove the water from their heads, they shake their heads and bodies, similar to a dog shaking, to shed water.Further, when raindrops collectively may weigh as much as 38% of the bird's body weight, hummingbirds shift their bodies and tails horizontally, beat their wings faster, and reduce their wings' angle of motion when flying in heavy rain.
