- Description
- Juvenile African Pied Starlings (Spreo bicolor) have a dark brown iris, but after the first year iris color changes progressively until adult birds have a creamy-white iris. Using light and electron microscopy, we found that the pigment epithelium of the iris remains pigmented, while changes occur in the pigmentation of the anterior border layer and the stroma of the subadult and adult iris. In the juvenile iris the anterior border layer is darkly pigmented, but in the subadult iris this pigmentation is lost progressively, while pigment granules are deposited in the stroma. In adults, the stroma is heavily pigmented with a solid refractory pigment, and the anterior border layer is clear.
