Aims
The aim of the Southern Colour Marking Group is to study various species of bird using colour marking in London, Essex and Hertfordshire. We do this by catching the birds using a cannon net, a technique requiring a special licence, or finding nests of breeding birds and marking the young in the nest.
Birds captured using cannon nets are extracted from the net before being marked with individually numbered metal leg rings. Whilst ringing the birds, we take measurements and study plumage characteristics. As many birds as possible are marked with a colour mark (either leg ring or wing tag) which can be read with a telescope without the bird being recaptured.
