The two chicks on Nest 4 were ringed yesterday and one fitted with a GSM/GPS transmitter.
One chick looked markedly smaller than the other. He weighed 1400g. He was given a Darvic ring Blue Y7.
The other chick weighed 1660g and was fitted with Darvic ring Blue Y8.
You can see the loose fit of the ring which indicates the gender is male.
Blue Y8 was also fitted with a GSM/GPS transmitter.
The young ospreys posed for Forestry Commission Ranger Paul when back home!
Professional photographer Neil Denham recorded the event for Forestry Commission England; many thanks to him for permission to use a couple of his photographs. And to Ranger Paul, as ever.
