There were 300+ Sandwich Terns around the point at Ynyslas again yesterday evening. The Mid-Wales Ringing Group have caught and colour-ringed 35 and controlled 4 British/Irish ringed birds in the last couple of nights. The Dunlin that Harry photographed was ringed at Ynyslas the night previous along with around 60 other Dunlin.
Last summer I read the ring of a Latvian colour-ringed Black-headed Gull (Yellow KJZ4) on the Leri, a couple of days ago I refound the same bird in exactly the same place.
