Abstract

Bird ringing allows close contact with different species and allows one to observe details that are impossible to see when viewed from a distance. In this study, we offer indicators for determining the age of Southern Pied Babblers Turdoides bicolor, specifically changes in plumage and the colour of the eye, bill, and gape. We reveal the developmental progression from juvenile to adult-like characteristics, typically occurring within 4–6 months. Additionally, we present moult data gathered from 24 individuals in Namibia, shedding light on the replacement of feathers and timing of complete moult events from this region. Understanding these age-related changes provides valuable insights into this species’ life history and ecology.
