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 hardly feels like a year since the birds were having to deal with exceptionally high tides but this threat has come around again. The tides this June could get up to 9.8m with the first real bad weather of the season forecast to coincide at the same time pushing the crashing waves higher up the beach. From Thursday to Saturday (14-16th) there will be debris to clear from fencing after each high tide. If you are free and can help we will be clearing this from 2pm onwards each day, meet down at the visitor center. With plenty of hands we can make light work of the seaweed and rubbish that gets caught up in the fencing and reduces it's ability to carry electricity.
On a positive note we have smashed the previous record for pairs at Gronant and we are now up to 170 as of today (12th June) with a few more still displaying on the beach.
