I don't think there's much else it could be apart from a Fieldfare,
They only do it to annoy and because they know it teases...... ;D
Blackbirds quite frequently have some white feathers so it's possibly a blackbird, but I don't think so as I've never heard of them having any grey, it's either black or white.My best guess would be a Ring Ouzel.
