What is the purpose of the "Cere" in raptors?

The cere is a significant anatomical feature in raptors, characterized as the smooth, featherless skin located just above the beak. This structure plays several critical roles in the physiology and behavior of birds of prey.

One primary function of the cere is to house the nostrils, allowing for effective respiration while the bird is active and during flight. Additionally, the cere can change color, signaling reproductive status and health, which is essential for communication during mating seasons. Recognizing the cere's distinctive location and purpose helps to understand the overall biology and behavior of raptors in the context of falconry and wildlife management.

Other options are related to different aspects of avian biology but do not accurately define the cere's specific role or characteristics.
