The park I saw it in is right next to the harbour, so that would be right, I'm sure you locals recognise it. I saw it fly and again I think osprey. My daughter was with me and she says she saw it on top of a high lamp post alongside the main road which runs next to this place about 2 days ago but she had no idea what it was....she's not really into birding!
On a less exotic note I saw a lovely nuthatch, many Robins, Great tits and Magpies.
If any of you birders can give me any clues I would be grateful.
