One for the twitchers...

I have had a couple of birds in my garden I don't recognise.

See?

Is it a baby thrush?

[pondhopper]

It looks like a very young recently fledged Thrush.

Not a clue, we don't have those, but it is certainly cute.

I'd agree it's a young song thrush, but to check, you can listen to one here, they sound pretty distinctive.

PS Do not type thrush pictures into google. Apparently the internet considers yeast infections more photogenic than song birds.
