And just like that, they started to leave...
It has been a fast and furious season. With most of the nests hatching first time round, the chicks fledged in what seemed like record time. Barring some sand-blow covering a few nests it has been a remarkably benign season, richly deserved after recent years. Consequently, the birds are leaving promptly having grown to an age where they can fly and follow their parents. It is rare though that any are seen away from Gronant on their migration, so when Robin Sandham and Marc Hughes found a flock of 8 on Colwyn Bay beach on 22nd Jul it was a notable occurrence and they took a closer look. The excellent series of photos below were taken by Marc (@Marcbuzzard on twitter).
Of the 8 birds, 5 were juveniles and the other 3 adults. One each of the juveniles and adults were colour-ringed showing they were from Gronant. Without the colour-ringing programme we could only speculate where they came from. The adult's code was XXX which means it was caught as an adult on a nest in 2018 but we don't know how old it was as it didn't have a metal-ring applied as a chick (there's always some that manage to hide from ringers!). It was DNA analysed for sexing so we know it was a male. The other colour-ringed bird was a juvenile with the code UJE applied just a few weeks ago. It too will be DNA analysed but we haven't heard back yet.
It was fascinating to see that the youngsters still get fed by parents once they have left Gronant. They will likely migrate in family groups all the way to Africa where the youngsters will become more effective at fishing for themselves. For now, if you still haven't seen Little Terns at Gronant this year you don't have long left. The best time is the hour or two before high tide. From Thursday onwards the site will start to be taken down but wardens will still be on site to speak to for a while yet.
