What nutritional advantage do darker colored meats have for raptors?

Darker colored meats, often found in species such as waterfowl and some game birds, provide a significant nutritional advantage for raptors mainly due to their higher nutrient and calorie content. The darker meat comes from muscle fibers that are rich in myoglobin, a protein that facilitates oxygen storage and transport within the muscles. This increased concentration of myoglobin not only gives the meat its darker color but also indicates a higher level of nutrients such as iron and essential fatty acids that are crucial for raptors' health, energy, and resilience.

Furthermore, the higher calorie content in darker meats is beneficial for raptors, especially during the breeding season or times of high energy demand, as it allows them to maintain their energy levels effectively. The additional nutrients help in muscle recovery and overall physical health, making darker meats an advantageous dietary choice for these birds.
