How does maintaining a bird on darker meats generally compare to lighter meats?

Maintaining a bird on darker meats generally requires less food compared to lighter meats due to the higher fat content found in darker meats. Dark meats, such as those from waterfowl or game birds, are typically more calorie-dense and can provide a higher energy yield for the same weight of food. This means that birds can sustain their nutritional needs with a smaller volume of food when they are fed darker meats, enabling falconers to manage their birds efficiently while ensuring they receive adequate nutrition. The more concentrated energy from the fat in these meats supports the birds' health and helps to maintain their body condition without overfeeding.
