What term describes the location on a bird where the feathers meet the body?

The term that describes the location on a bird where the feathers meet the body is "base." This is the part of the feather where it is attached to the bird's skin. Understanding this term is essential for various aspects of falconry and bird care, as it helps identify feather conditions, growth patterns, and overall feather health.

In the context of avian biology, the base of a feather plays a crucial role in its function and structure, as it helps ensure that the feathers can withstand various forces and work effectively during flight. Knowing this terminology assists falconers in recognizing signs of molting or feather damage, which can affect a bird's performance and well-being.
