TRIP - Pitsea - 25/03/2017: Our last field session for this winter. A small but experienced team assembled and the wind got up really quickly. Not many birds on the tip and clearly there had been a big clear out. One of the first birds I saw on the tip face was a nice first winter Caspian so we were hopeful of something different. We got a nice early dust cart with plenty of food and once it was rolled over we had birds down. It took some time for a window to appear with birds hanging in the wind making taking a catch really difficult. After several lifts and nothing interesting in the catching area I decided to attempt a catch and with good safety from Dave we soon took a catch of 201 birds. We decided to re set and just see what happened whilst we were processing. A second lorry with more food on it was soon flattened in front of the net and plenty of birds came down. Very little of interest but then a Caspian was hanging over the catching area but not landing. Rich then found a Glaucous Gull which was flying around but again just would not land so it soon went off high to the south. We waited and waited and eventually another Caspian was hanging in the air about the catching area. With very few birds in the catching area I only needed it to land - as soon as it did I took the catch including the Caspian - a great way to finish the season. Huge thanks to the tip and a great team effort again.25-Mar-2017

TRIP - Pitsea - 11/03/2017: On arrival at the tip the tide was out and there were no birds!! Slightly worrying as it was also a warm day. We set none the less and shortly a bin lorry arrived to which a good number of Black-heads appeared out of thin air! A few quick roll overs with the compactor and we soon had a lot of birds down in the catching area. Once safe a decent catch of just under 300 birds was secured.11-Mar-2017

TRIP - Pitsea - 25/02/2017: A team led by Aron whilst I was away proved successful and kept our numbers for this winter up. A good catch of 248 birds in windy conditions was a useful addition to the annual totals.25-Feb-2017

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.
