Some types of bats are still able to fly in a light drizzle conditions. However, when more torrential rain, they immediately seek shelter. New research published in the journal Biology Letters, revealed the reasons why bats do that.
Apparently, the bat must try harder to fly when the feathers and their wings are wet.
In a series of studies conducted in Costa Rica, the researchers studied the behavior of Sowell bat (Carollia sowelli) short-tailed, bat species from the family Phyllostomidae are commonly found around Mexico, Central America, to Panama when they fly in captivity large in size.
Quoted from Science Now, researchers occasionally wet bats it with tap water, sometimes let the bats fly wet under heavy rain.
From the research revealed that the bats that use energy twice as big as they fly in wet conditions compared to when they fly in dry conditions.
Flying in rain conditions are no different. It abolished the alleged mechanical problems caused by raindrops falling on their wings or the weight of the water droplets to their responsibilities.
According to researchers, wet bat, just like other mammals that was wet, cold. For that, they need to work harder for their bodies to keep warm.
In addition, with the number of water over the hair and moisturize their wings, wet conditions are also of course make no aerodynamic for bats into the air.
