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!
It seemed to take forever but the first Little Tern eggs were spotted on the 20th May (first egg date 19th). This is 4 days later than last year. The terns had been back a month and showing a lot of interest in the breeding pens. We think although the birds were ready to lay their eggs earlier, in the nice weather, they were waiting for the high spring tides to pass, very sensible of them! It's all go now and since the first nest was spotted we are already up to 20 active nests and many more to come. If you have not been down to see the terns yet this season now is a good time with so much activity to be seen.
