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.
Friday 1 December
A few hardy people met on Friday evening at the fieldwork base in preparation for an early morning mist-net catch at Gedney. The small team included three people who were on the Wash for the first time. Aron and Alyce had been out on the marsh in the afternoon to plan the catch and to leave guiding sticks to help the team to find the route later in the dark. Aron and Alyce had also prepared supper for those that wanted food and plans were made for timings with a realisation that a 04.37 high tide necessitated leaving the base at midnight! The equipment was packed into three cars before the team headed to bed for a short sleep.
Friday 17 November
This was a second weekend for the group with no opportunity for making a cannon net catch. However, there was a double opportunity for mist netting, along with the usual colour ring resighting on one tide. The mist netting sessions were initially planned for the high tides on both Saturday morning and Saturday evening but, as with all WWRG field trips, this was dependent on the weather.
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.
Friday 22 September
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.
