A month after devastating tides down at Gronant wiped out 2/3 of all nests, it was with bated breath to see what this month would bring and kept a close eye on the daily forecasts hoping that the settled weather would continue. This time it seems, the terns have been lucky and the tides have barely reached the protective fencing. There will be a little work to clear debris in some areas but nothing significant. Phew! Just in case the tides were bad the wardens prepared nests in the usual way, by moving them slowly up the beach or by carefully placing the nest on a plant pot or bucket (as shown below).
In the last few days there has been a mass-hatching of eggs with the majority of re-laid nests successfully reaching this stage (including the two nests being beamed in to the visitor center). The photo below shows an egg with a pipping youngster inside pecking its way out. You may notice the little white speck on the end of the bill of the chick. This is known as the 'egg-tooth' and it is a temporary calcium deposit which helps the chick break through the egg. Isn't nature clever!
More of a concern is the continued predation from Kestrels. Despite the best efforts of everyone on site the Kestrels are persistent and occasionally succeed in taking chicks and fledglings. Many of the successful tern families have moved away now as there is nothing keeping them at the site and remaining here is endangering themselves and their offspring. For the remaining birds, we need help from volunteers to station themselves around the site and scare off the Kestrel when it approaches. It doesn't always work, but every successful occasion for us is one more chick to make it to fledging. Any help gratefully received!
Thanks to everyone who came down for the official opening ceremony of the Visitor Center and Hide at Gronant on a sunny and hot Sunday afternoon. We are grateful to Tony Thomas, lead for the environment in the council, for presenting a speech and cutting the ribbon. A group shot of the event is displayed below. It was a bit hot but refreshing drinks were flowing.
For something a little different, the following is a write-up by Maddalena, an Italian student doing a placement down at the tern colony a few weeks ago:
"I started my experience as a volunteer in the tern colony yesterday (19\06) and I was fascinated by all the work that’s put in the welfare of the birds. Being a foreigner I had never heard of the Little Terns before but I quickly recognised the beauty and importance of these shy sea birds and why they need our help to keep their nests safe and undisturbed. As a new and inexperienced volunteer my first day was spent mostly observing, listening and learning from the wardens that were fixing the damage done by the storm, but also helping actively by cleaning debris and carrying equipment, always careful not to step on the little chicks! A lot of work is put in to prevent predator attacks, checking the electric fences and making stone barriers to keep out the foxes and looking out for air predators such as the kestrel, but its noticeable these little birds are not defenceless, scaring away seagulls and dropping near your head to try to distance you from their nests. I really enjoyed my time there and the wardens have been nice and willing to tell me all about the colony and included me in their work whenever possible, even showing me one of the little chicks, but most importantly encouraging me to go look for a more naturalistic-oriented path for my future. I highly recommend trying the experience of volunteering in the colony, not only for its beauty but most importantly for what it can teach everyone."
In the next week most of the re-laid nests will hatch, but there will be high tides over the weekend. With the fairly benign weather there shouldn't be a repeat of a month ago but there may be debris to clear from fencing. Kestrels are around and taking some chicks but we are doing everything we can to reduce their damage to the colony. An update on that will be forthcoming once we know how successful the attempts at distracting them from tern chicks have been.
