Weaver ringing on the Cape Peninsula, 2010

This year the main aim of the ringing was to recapture as many weavers (that had been ringed as weaver chicks) as possible. At the same time much ongoing data was obtained for survival and movements of weavers and other species on the Cape Peninsula. 54 species were caught, with a total of 2907 ringed and 581 recaptured (these totals do not include ringing by Sally and others). A full species list of captures on the Cape Peninsula is given below (see also totals for 2009 and 2008. A photo gallery showing bird ringing events in the Cape Town area may be viewed here. To join bird ringing events in Cape Town, check dates on this calendar.

Funding was gratefully received from the African Bird Club Conservation Fund and the Cape Tercentenary Foundation to study natal dispersal in weavers.
