Unknown (Shore?) Bird - Northern Germany (1 Viewer)

[WRL]

Hello,
on October 7th, 2021 I watched, amongst others, a (shore?) bird I cannot ID. The setting was marsh land at a confluent to the river Elbe (estuary, close to the North Sea), Germany. Please see attached photos (I mean of course the bird between the mallards). Any ideas?
Thank you and regards,
Werner

Looks like an (overexposed) juvenile Coot, look at the lobed feet.

I was thinking it looks - rather bizarrely - like a little grebe.

I think shape, colours and especially bill are off for a young coot. They are mousey grey with longer necks than this. An unusual view of a little grebe for me

Little grebe

Looking again, I’ll happily agree with a little grebe.

Thank you, guys. I'll take the majority vote for the Little Grebe.
Regards,
