Black-headed Gull - Green JZ20

Robin Vage got in touch last month with reports of large numbers of gulls at Corbet Lough, Co. Down.

This site normally has a small wintering flock of 20-30 birds, but numbers had swollen to a couple of thousand at the start of February and it seemed inevitable that something interesting was going to turn up.

As well as a returning Lesser Black-backed and a Mediterranean Gull, two birds with NI colour-rings were recorded. In addition, Robin recorded a Black-headed Gull with a green colour-ring and another with a white colour-ring.

Robin reported his sightings and heard back that the green ringed bird, JZ20, had been ringed as an adult female in April 2016 at Engervannet, Sandvika in Norway.

It was re-sighted nearby the following day, but this was the first report since.

Great work by Robin and many thanks to him for passing on the information.
