Who/what does a poo like this?

Jackdaw or crow? I found some ‘unusual’ poo last week and am now feeding a pair of hedgehogs on my patio - they’re lovely and I’ve called both of them Spike!

Think it's bigger than we usual get from either. And it is green and white.

Pigeon or seagull? We get both here and what you’ve shown is very familiar!

I maybe should say that it doesn't appear to have bones etc in it.
