What is generally true about dark-colored meats for raptors in comparison to white meats?

Dark-colored meats, which are typically richer in myoglobin due to the increased physical activity of the muscle, tend to have a higher caloric value compared to white meats. This higher caloric content is important for raptors, as they require more energy to sustain their high metabolism and active hunting lifestyle. The additional fat present in dark meats also contributes to this increased caloric density, making them a preferred choice for providing energy to these birds.

While white meats can still provide nourishment, they generally contain less fat and fewer calories, making them less suitable as a primary food source for raptors that need to maintain high energy levels for flying and hunting. Therefore, the higher caloric value of dark meats aligns well with the dietary needs of these birds of prey.
