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.

A slightly frustrating day a set for either Wigeon or Brent Geese was slightly strange in that there were no Wigeon at all on the fleet and most of them were out on the creek for the whole of the day. However, over 1,000 Brent Geese at Marsh Farm saw groups on the catch field early on and we elected to take a small catch of 6 birds really early as we knew we could re set. Following the early success several larger flocks congregated on the catch field and we were very unfortunate to not have a large number in the catching area on a few occasions. Attempts to "twinkle" them were very nearly successful but a screaming child and a Sparrowhawk meant we were unlucky. Eventually a an opportunity to take a second small catch arose and firing on five birds resulted in a three being caught.

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.

The group operates with the excellent support and cooperation of The Essex Wildlife Trust at Blue House Farm which operates the nature reserve and allows access for Brent Goose catching. The Lee Valley Regional Park Authority and the London Wildlife Trust allow us to access sites in the Lee Valley Park for Heron and Egret work. Richard Bott kindly allows access to woodland on the Bott Estate for Red Kite monitoring.

We are grateful to the Essex Birdwatching Society and Essex Field Club for providing funding for the colour ringing programme for Brent Geese, London Wildlife Trust for Herons and Jenny Weston at the RSPB for support with Red Kite wing tagging.

The development of the dynamic mapping was supported by a grant from the British Birds Charitable Trust.

We also acknowledge financial support from Merlin Ringing Supplies.
