They are now down to four cygnets, on Monday there were six, Wednesday five and yesterday four. On Wednesday, four came out with the parents and it was about another five minutes before the fifth swam out of the reeds and it looked slightly unstable and under the weather but did join in the others eating the food.
This similar to what happened in September of 2014, when the cygnets were much older, at the time, they looked small for their age, generally under nourished and disappeared one by one.
We will keep monitoring the family and update the site accordingly.
