Over the last two or three years WWRG has increased its efforts on the resighting of colour-marked birds, recognising that this provides valuable data in terms of the number of recoveries and the information gained on the movements and survival of birds that have been ringed. Previous blogs have outlined the fieldwork undertaken by WWRG in the last quarter of 2017, including colour-ring resighting, particularly the ‘Colour-mark resighting bonanza’ weekend of 6–8 October when 146 sightings of 88 birds were made over three tides.
One of the most interesting aspects of ringing with WWRG is the information that we receive on birds that we have ringed which turn up in different places both in the UK and elsewhere. These may be re-sighted from colour marks on the legs of a bird or from the bird being re-caught, either through mist netting or cannon netting, by another ringing group. Increasingly we are also receiving reports from individual birders who have read the metal ring of a wader in the field, an indication of the quality of modern optical equipment and the interest of birders in the finding of ringed birds.
Friday 6 October – Sunday 8 October
With many of the usual team members away in faraway places, poorly or with car troubles, a small team collected at the fieldwork house with plans for a weekend of colour-ring resighting and the possibility of a mist netting session on Saturday evening. The likelihood of mist nesting was always doubtful due to an unsettled weather forecast. The forecast had deteriorated by mid-morning on Saturday and a decision was made that this would not go ahead.

The weekend began, somewhat unusually, with a mist nesting session on Terrington Marsh. This required a small number of people to arrive at the fieldwork house mid-afternoon to set the nets on the marsh ready for the evening catch. Two lines of nets were set, one on the E-pool and the second on the cannon-netting pool, with Ron and Nigel leading the respective teams.

The autumn Wash week began with the combined Norfolk and Lincolnshire teams convening at the Norfolk fieldwork house on Saturday afternoon. This followed some uncertainty as to whether the planned mist netting session would be able to go ahead based on weather predictions. A recce at Gedney had taken place earlier in the afternoon with glow light markers in place for finding the way across the marsh at night. With the go-ahead agreed, the team headed off to bed for a very early start the following morning.
