However, studies show that trimmed poultry's adrenal glands weigh less, and their plasma corticosterone levels are lower than those found in untrimmed poultry, indicating that they are less stressed overall. This illustrates both flight's importance in avoiding predators and its extreme demand for energy. When in gliding flightthe upward aerodynamic force is equal to the weight. All have a white belly.
