Two Ospreys were reported northbound at Portland Observatory 4.30 ish yesterday afternoon so quite likely one of those was the Avalon Marshes bird a couple of hours later - they have just reported another, and a Red Kite about a hour ago so definitely the time to do a bit of Sky watching.
I had an Osprey being mobbed by a Raven over the reserve at Asda in Frome this morning (6th April). After a brief tussle, it headed north over the town, possibly heading for Chew.
Possible Osprey heading north-east high over Butleigh early afternoon today. It was clearly a raptor & significantly larger than the Buzzards circling below it.
