Explanation:
Detailed explanation-1: -When a bird engages in gular fluttering, it first opens its bill widely, and “flutters” the muscles in the throat (gular muscle) while breathing rapidly. This action helps to carry heat out of the body quickly through the lungs and air sacs, while bringing in cool air to help regulate body temperature.
Detailed explanation-2: -Since birds have no sweat glands, heat must be lost through the respiratory tract by panting, or in nonpasserines by the rapid vibration of the upper throat and thin floor of the mouth ("gular flutter").
