Last night David Tompkins and I had a netting session at Ynyslas to try and colour-ring a few more Sandwich Terns. This set of high tides has been a bit frustrating so far as the wind has ruled out the use of mist-nets and so we have been relying on dazzling, and terns don’t dazzle! Although there have been a few Sandwich Terns around they don’t seem to be using the point as a roost and we failed to catch any on this set of tides. We did however catch two Common Terns and two Roseate Terns. These are only the fourth and fifth Roseates to be caught at Ynyslas. The previous three birds had all been ringed in the Republic of Ireland and it is almost certain that the juvenile we caught wearing a ring last night has been too. The adult it was with was unringed, and given the intensive ringing projects in operation in Ireland for this species I bet there aren’t that many of them around.
A first for me was the capture of an adult Knot. It is not unusual to catch Knot in small numbers at Ynyslas at this time of year but they are invariably juvenile birds freshly arrived from their breeding grounds.
Over the set of tides we managed to ring a total of 247 Dunlin, 9 Ringed Plover, 6 Knot, 4 Oystercatcher, 2 Turnstone, 1 Greenshank, 1 Redshank, 1 Sanderling, 1 Curlew Sandpiper, 2 Common Terns and 1 Roseate Tern (plus the control juvenile). Many thanks to David, Mark Cutts and Jane for their invaluable assistance.
