Birds use their skin and gills to breathe, right or wrong
The answer is: Error.
Birds do not use their skin and gills to breathe. The primary organs that birds use to breathe are their lungs and air sacs, which are connected to their nostrils. Birds have an efficient respiratory system that allows them to fly at high altitudes and generate enough energy to sustain flight. Oxygen is taken in through the nostrils and then diffused through the lungs, air sacs, and tissues. This process is very different from other animals such as fish, which use their gills and skin to breathe. Birds, unlike fish, need oxygen from the air to survive.
