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.

Latest recoveries

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.

Colour-mark resighting bonanza

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.
