TRIP - Rainham - 02/03/2013: A very hard day at Rainham today. The tip staff were fantastic and persisted in helping us get gulls into the catching area resulting in a single catch of 168 birds. 166 Gulls and two Carion Crows making two ringers happy with ringing ticks.02-Mar-2013


TRIP - Pitsea - 16/02/2013: It has been known that in Feb we can take large catches of Black-headed Gulls. Well this was a megga day! Our biggest day ever with a grand total in two catches of 845 birds. Some fantastic work by the compactor driver Alan got lots of birds into the catching area and two nice catches were taken.16-Feb-2013


NEWS: On Tuesday 12th February the NTGG took three members to assist Jez Blackburn with an attempt at a catch at Milton Tip in Cambridgeshire. This site was used to catch gulls many years ago by Jeff Kew and there has been no activity on this site for probably well over 20 years! However Jez has now obtained permission to ring there.

We all had to do another induction and any new ringers operating on the site will need to undertake one.

The tip is a very small affair and probably only has two or three years capacity before it closes. However, it is an interesting site clearly used as a feeding site by many of the gulls which migrate through the UK inland and over farmland, specifically Lesser Black-backed Gulls. This was borne out by the catch we took which included 70 of this species, almost all of which were adults.

The tip staff were fantastic and again their co-operation and hard work was the main thing that ensured that we secured a catch. The total was 190 new birds and one control comprising the following:

Black-headed Gull - 98 new, 1 control (Lithuania)
Lesser Black-backed Gull - 70
Herring Gull - 19
Great Black-backed Gull - 1
Yellow-legged Gull - 1
Total - 191

Jez is planning another trip on 19th March and if any NTGG members are available to assist please contact Jez direct . 14-Feb-2013

Aims

The aim of The North Thames Gull Group is to study the gulls making use of the landfill tips on the Essex coast of the Thames estuary, east of London.

We do this by catching the birds feeding on the waste using a cannon net, a technique requiring a special licence. The first step is setting the net.

Once captured, the birds 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. A sample are given orange colour rings which can be read with a telescope without the bird being recaptured.
