Thanks for the advice!
I have seen Chough at Waterville ,walking the beach north of the village towards the low cliffs. One fly-over adult ,one fly-over juvenile and two adults flying around the cliffs. Added bonus was a mediterranean gull at the same beach and two whimbrel.
Had a boat trip round the Skelligs with Manx shearwater, puffin , Gannet, razorbill, guillemot, black guillemot (the latter only at start and return in Portmagee),northern fulmar , shag, kittiwake, great blackbacked,lesser blackbacked,common and herring gull, a common bussard (near coast,flying overseebut straight to the nearest land),and a single small dark, whiterumped storm petrel with tail appearing square,but didnt see any white band on the underwing. Not really sure if it was european storm petrel
