On behalf of Laura who sent in an email:-
I saw a bird in my garden in East London this week that I'd never seen before. Unfortunately I didn't manage to get a photo.
It was larger than a sparrow, almost the size of a thrush.
Black cap and black throat, and russet coloured around the eyes.
I've scoured the internet but can't find what it was. The nearest thing is the black throated thrush.
I'd really appreciate any advice please.
