What is an eye-ring?
The eye-ring of a bird is a ring of tiny feathers or bare skin that surrounds the outside of the eye.
The eye-ring is often decorative.
The colour of the eye-ring might be the same colour as its surrounding feathers. This makes it difficult to notice.
The colour of the eye-ring might be a different colour from its surrounding feathers (called a contrasting colour). This makes it easy to notice.
