What part of a raptor's anatomy is referred to as the tarsus?

The tarsus refers specifically to the scaled shank or "leg" of a raptor, which is an important part of its anatomy. This region plays a crucial role in the bird's ability to perch, capture prey, and maintain balance while in flight. The tarsus is essentially the segment between the bird's foot and its body, and its structure helps provide support and strength, which is vital for the raptor’s predatory lifestyle.

Understanding the tarsus is essential for anyone studying falconry or raptors in general, as it helps illuminate aspects of a bird’s physical capabilities, such as the power with which they can strike and grasp their prey. The scaled texture of the tarsus is also a distinguishing feature in identifying different species of raptors.
