Various aspects of weaver demography are being studied on the Cape Peninsula. The key factors are survival (and movements), which is being studied by ringing, and breeding which is being studied by monitoring colonies and ringing chicks. In the course of ringing weavers, other birds are caught too, like this juvenile Pied Crow (photo: Gabriel Jamie). To obtain data on survival and movements a large number of recaptures is needed, with ringing at a network of nearby sites. A full species list with numbers ringed and recaptured on the Cape Peninsula during 2011 may be seen here.
