A new study has been launched to ring weavers in a way to maximise data for geographic variation in survival rates. Weavers are fairly easy to catch in large numbers, making them ideal candidates for large-scale studies. Species that could work well include Southern Red Bishops and Southern Masked Weavers. The key is to ring at sites where weavers are often recaptured. Ringers are able to contribute to this project in their normal ringing sessions. Read more here.
