Back in mid April, was this adult still on its way back to Scotland at the time, or was it likely to be breeding somewhere else?
Much more recently in Sept, a colour-ringed juvenile black-headed Gull was recorded at Pembroke Millpond (reported on the Blog a week or so ago). The origin of this bird is still to be determined but two of the digits on the ring are similar to those on colour-rings recorded on two adults at the Millpond a couple or so years ago. So, most likely the Millpond juv will have been ringed (like the other two were) in Poland - awaiting confirmation.
