Trying to ID bird call-Greater London (1 Viewer)

[Emi]

A couple of days ago a bird the size of a thrush and light in colour flew low over my garden, it had a 2 note call that sounded like " chook chook " it wasn't high pitched or coarse like a crow. Three of us have spent ages trawling the internet for bird calls and nothing sounds remotely like it, any ideas please

I don't think so, the bird was kind of dumpy with a short tail.

It may well of been but didn't look like a black bird male or female lol but then again it was very quick. Never have I ever heard that call before yet im surrounded by blackbirds, think I shall have to listen harder. TY

Who would of thought it was something so simple 😂 Thanks guys you saved my sanity.

I wonder could that be a partially leucistic male, because of the yellow bill? Or is that just a consequence of the overall lightness
