Is this a bird? Seen in UK (1 Viewer)

[StarBurst6]

Hello everyone,
I have some perplexing pictures taken today in the UK. I see something pale in a tree hollow (roughly centre of the pictures) and I am not sure whether this is a bird. I understand that the pictures are low quality and so I do not expect to be able to say for sure, but does anyone have any ideas?
Thank you,
StarBurst

I think it is just a tree. If you can revisit, and it still looks the same, that would confirm it.

 

[StarBurst6]

Yes I will try to revisit soon to see if it's the same

Is this what you're looking at Starburst?

Looks like something occupying the hollow of a tree - but I can't make out what.

 

[StarBurst6]

Yes, this is what I'm looking at, I haven't been able to determine what it might be

Looks like a Sparrowhawk for me.

Once you get the nose and the eyes in the right place - yes, it does (look like one).

Well sharpened up Richie, more likely a Kestrel but yes, appears a beak and eye, as Butty says, looking towards the camera.
