Southern Colour Ringing Group


Another visit to the colony at Waltahastow today saw a second check of Herons and Egrets with a good number ringed.

Last visit to Netherhall this year unfortunately very few Egrets this year. Two nests ringed and one will 3 eggs. One final nest of Herons ringed as well.

Walthamstow and Netherhall both checked today. A nice sample of 16 birds ringed. Ineterstingly at Watlhamstow the Egrets were very early and mostly with full clutches we we will need to visit in early May again to get the Egrets at the right size to ring.


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.
