The avian digestive system is a remarkable example of evolutionary adaptation, tailored to meet the unique needs of birds as they navigate their environments. Unlike mammals, birds have developed specialized structures and mechanisms that facilitate efficient digestion and nutrient absorption, essential for their survival and energy needs. The bird digestive tract is not only shorter than that of many mammals, but it also features compartments that allow for the processing and breakdown of food in ways that optimize nutrient extraction. Birds are primarily adapted to a diet that can range from seeds and fruits to insects and even small vertebrates. This dietary diversity has led to a variety of digestive…
