Majorca - Tale of Two Ospreys

We watched this first Osprey bring in fish on two separate days. The first fish was very large and ?she took a couple of hours eating it. On the second morning the fish was smaller but she didn't seem to have any appetite despite making room by defecating copiously.  In the after on the second day we watched a different Osprey catch a fish behind a bak of reeds and the carry it off to a suitable perch elsewhere. This second osprey has a radio transmitter on its back. I wonder where it was tagged
