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!
We are pleased to announce, after lots of planning and testing, that live-streaming is operational at the Visitor Center in the Gronant Dunes. Images are being beamed in from a couple of nests and the birds are currently on eggs. In about 10 days they are due to hatch and there will be great opportunities to see a tern's-eye view of the chicks being fed. Below is a snapshot of an adult sitting tight on its eggs. It takes luck (or great patience!) to see a changeover or food-pass, but is exciting when it happens. One adult on each nest is also colour-ringed so it is possible to see which adult is tending the nest at any one time. To see it for yourself please visit the site.
Numbers of birds have peaked lately at 420 adults, an increase on the roughly 350 which had been spending the summer here. We think this is likely due to an influx of failed breeders from other sites around the Irish Sea. It is getting late for these to start nesting now. They would still be around in Mid-August if they started now. Saying that, there are still displaying birds down on the beach. Of pairs that did re-lay we are over 80 active nests. The calm weather looks set to last, but whilst weather isn't a threat right now, a pair of Kestrels certainly are. They are being seen increasingly frequently. Consequently, any volunteer help down at Gronant will be very helpful in the coming weeks.
We are at peak Little Tern! The season is now at it's zenith at Gronant with most of the pairs incubating eggs. At times there have been up to 370 Little Terns, although counting them is an art-form when they are whizzing around. Peregrines are causing daily panics for the birds but to our knowledge there have not been any depredations yet.
It has been great to see so many people visiting and enjoying the terns this season. If you have not been yet this year, head down to the visitor center and the wardens will show you birds sat on the nest. (Directions on the 'Gronant Dunes' page).
This Saturday the North Wales Little Tern Group will be down at Nantclwyd y Dre, Ruthin for the Nature Day being held there. If you are near please pop in and we can answer any questions you may have or sign up to join the group. There will be many wildlife groups present and you can join in with a 'bioblitz'; recording as many species as possible in the day. Entry £2. See poster below for more details.
