WWRG in Delaware – part 2

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.

Foreign visitors

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.

December mist netting

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.

Fieldwork November 2017

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.

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.
