The Wash Wader Ringing Group recently received a recovery report from the BTO of a WWRG-ringed Knot caught in Guinea-Bissau: the first recovery of one of our Knot in that country. This fascinating recovery prompted a more-detailed look both at the circumstances of this bird’s capture and the historical records of Wash recoveries from western and southern Africa.

Storm Dennis!

Sunday – strong winds with rain
Recce and plan for the weekend
The plan for the weekend was for a cannon-net catch on either Saturday or Sunday morning depending on the findings of the recce team on Friday morning. One of the aims for the weekend was a trial for catching waders on a non-spring tide – the tide heights were considerably lower than those for a normal catching weekend. Mist netting was not an option for the weekend due to the tide heights.

Election day at home led to discussion in the Shorebird House as proxies had to be instructed. Then out to do resighting and surveys as we are in a new survey period, before showers and clean clothes to head up north (with a side trip to Bombay Hook in a thunderstorm for some) for our, now traditional, BBQ with Dave and Marg – a great time as usual, with food, drink, discussion and fireflies.

So the weather in Delaware has continued to be unseasonably wet; although not always as wet as the forecast suggested, we have been woken in the night by the rain at times. We had the same catching plan for three days, with the heavy rain and wind meaning that we couldn’t get out on the first two days – saves writing new plans on our wipe board each day and also means we get more data input and checked. We did get out in the afternoon on Saturday to try to make a catch of Sanderling for a PhD project – we found Sanderling on the north end of Prime Hook Beach and went to set. We had issues with Grackles and Blackbirds scaring the shorebirds but managed to get a small catch, but only two Sanderling.
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.
