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.
We recently received some reports that birds ringed by WWRG had been seen or found elsewhere. Click on the points on the map below to see the details of the birds reported abroad.
