In case of saving batteries we paused the MMS transfer, but as June was time for checkings and ringing, we got some information. Unfortunately there are many losses in clutches.
Nests mentioned in previous posts:
Ruszcza: no birds
Chrustowice: the control showed 2 pull. (doing the ringing on this tree is too risky so we did not climb)
Rzemienowice: 3 pull. in good condition
Szczeka: no birds
Having climbed the tree and fastly checked the data on the device, it showed all chicks hatched but after a few days all died for unknown reason. Maybe a closer analysis on the autumn will tell why.
