In the last couple of weeks since the relaxing of travel restrictions we have been able to look for colour-ringed birds on the beach at Gronant. A bird with a combination of rings we hadn't seen before piqued our interest and we have since found out it was ringed near Lisbon, in Portugal, in Sept 2018 as a juvenile on migration. As far as we can tell, this is the first ever Portuguese-ringed Little Tern to be seen in the UK!
This fills in another piece of the puzzle as to the route Little Terns take to get to Africa for the winter. At over 1000 miles away it is an impressive flight but a fraction of the total journey these tough birds make. The North Wales Little Tern Group are really pleased to discover this first and by working with Denbighshire Council and the Merseyside Ringing Group we hope to make more discoveries in the future.
In terms of the season at Gronant, rather like the year for humans, it has been a very tricky one for the terns. Following most of the first round of nests being lost in a storm in early June, about 80 pairs relaid. Since these eggs hatched, the ringers have confirmed over 50 chicks in the colony but a lot of these are being lost to sand-blow and intense Kestrel predation. We know some have made it as there are now fledglings on the beach. Up to a dozen young ones so far. We think that the numbers will continue to rise over the next week or two. We'll let you know the final totals when we have them.
The weather has improved lately and this is good timing for the chicks which now roam the beach and dunes at Gronant. Around 250 chicks have been metal-ringed this season, by far the highest ever, hopefully a sign of good things to come. A lesser number have also been colour-ringed for future resightings. At present the chicks are anything but easy to spot, sensible really. See the photo below for one hiding in the prickly Sea Holly for safety. The next couple of weeks will be crucial for those chicks to make it to fledging without being predated or affected by bad weather. There was hushed rumors today that the first chick had fledged, when it was seen to take a short flight down the beach. Great news!
There is always a flip side and that is that the Kestrel was seen to take a chick to feed on in the dunes. We are putting out food on the diversionary feeding station for the Kestrel which is working to some extent but not always and we need volunteers to come and do a predator watch in case it comes back. Please please please consider popping down for an hour or two to help out over the next couple of weeks.
Finally, the dunes are a riot of colour at the moment, largely thanks to the thousands of Pyramidal Orchids which have spring up from the sand. This makes the walk down to the colony all the more enjoyable, we've had just as many comments about the plants as the birds lately!
It's been a week of mass hatching, with almost all of the first nest attempts now turned from smooth eggs, into fluffy, helpless bundles. Miraculously, the bad weather last week didn't cause too many issues, other than a few buried nests. Now the weather has improved, just in time! Right on cue though, the Kestrel is getting seen more often. They are not stupid and will be able to detect the chicks from quite a distance. All eyes will be on the lookout for any Kestrel advances in the coming few weeks.
A rather special Little Tern sporting Yellow ZBA colour-ring has been recorded tending 3 eggs. This male bird was originally ringed as a chick by Professor David Norman of the Merseyside Ringing Group in 1993 before having a colour-ring added in 2018, also by David, when it set a new world record for longevity. It is now back for its 26th year, still making it the oldest known Little Tern in the world, ever. A nice little coincidence, it was refound on father's day of all days. We are so pleased to have this bird back. It has made looking through hours of footage from nest cameras by students and volunteers from the tern group so very worthwhile!
It has been a busy week down at Gronant and not for the reasons you might imagine. The birds have been looking after themselves a lot more, with the chicks growing up quickly and with little interest from Kestrels now the feeding station is working so well. Instead we were inundated with the media following a press release circulated about the new visitor centre and hide. A crew from BBC Wales came down to film a piece for their 6.30pm 'today' news programme. A clip of the interview is posted below.
There will also be a radio interview on the season coming out on the BBC Wales country focus programme some time in August. An article was also published today (30/07) in the Daily Telegraph about the season. Great that the colony is getting the media attention it deserves and for all the right reasons too!
Tern-wise the chicks are growing up fast and in the next week we'll see how many have made it to fledging. Of slight concern has been the regular presence of a Weasel which was cheeky enough to peek its head in to the visitor centre the other day and stared eye-to-eye with a surprised warden!
If you would like to come and help us take down the site, there is an event on 10th August at Gronant beach from 10am and your help would be very welcome.
Since the last update, everything has been going rather well down at Gronant. There have been up to 190 chicks hatch out with the last nest hatching yesterday (22/07). We are definitely in the last phase of the season with chicks starting to move away from breeding pens and certain parts of the colony falling quiet for the first time since May. Saying that, there is still a fantastic amount of activity around most of the site and it is good to see no shortage of food being brought in for the growing chicks. The photo below shows a rapidly growing chick hiding amongst the rocky terrain on the seaward facing shingle bank.
It was nice to see the NWLTG mentioned in a recent news article about the new visitor centre on the BirdGuides website. To read the article please click the following link - https://www.birdguides.com/news/denbighshire-council-opens-little-tern-visitor-centre/
There is an event on 10th Aug at Gronant from 10am to take down fencing at Gronant and a BBQ lunch. Please attend if you would like and bring something towards the BBQ. Taking down the site is always more relaxing than putting it up (no post thumping required!) and it should be a fun day so long as the weather holds.
