I saw this unusual wee bird today, Googled it and one site says ‘extremely rare Blackcap’…
Yes, I would say it is a male Blackcap. A lovely bird to have visit your garden and nice photo.
Having looked at the spiral feeder you may like to take a Quick Look at this LINK; I don't know if all have been withdrawn from sale but something to be aware of.

I agree
As per Hazy re I.d. (Blackcaps aren’t rare in UK) and as per Hazy re feeder being a known issue.
Thank you. What an awful thing. Taken feeder down immediately.
