The four chicks were ringed yesterday, an event not unnoticed by their parents as they circled above and shrieked at their unexpected visitors...
As well as ringing, a range of measurements such as weight and feather length were taken, with the weight allowing to tell how many male and female chicks there are. Which turned out to be 3 males and one female this year. The three males all seem to be pretty equal in weight, and look to be getting their fair share of the food.
