Premature Pigeons Providing a Platter.

Corvid

I think this is cat.

It could be possible it was raided/dropped, initially, by a corvid or squirrel and the cat came along after.

Quite possibly another bird going by the impact and the hole (diamond shaped) you may have spooked it and its flown off, cats generally dont take eggs out of nests even low ones, more likely to take fledgelings, you usually find tree nesting birds get their nests burgled by corvids and the ground dwellers clear them up after they are dropped etc... look at the egg carefully to see if there are any other scratches or marks that may have been made by beak or claw or beak peck marks, also place a coin or another size indicator, that always helps

There's two puncture marks, the other not very easy to see in the pic.
I'll pick it up later and look closer.

Why do you think cat when there are a few other possibilities, notably a member of the mustilidae family, who loooove eggs.

My office is surrounded by buildings and is in the centre of town and there's cats all over the place.

 

[blacktimberwolf]

That's a pretty good reason

My fault really, I should've put it into context.

No mate, that's a fly

Are the pics recent?because its late in the season for egg laying,some birds will have a second or third clutch if unsuccessful in hatching eariler clutchs.the dead leaves on the grond look like leylandii,was there recent pruning done which may have knocked nest out of hedge and predator had a go!also its abit late for the fly(blue bottle i think?).a good indicator of timescale would be if there were any fly larvae present in the remaing yolk,which would put it within the hour.

 

[Bushwhacker]

It's still summer here, warm as you like and the photos are fresh. Oh and I think it's just a common old flesh fly.

Caught this bugger out there this morning.

case closed then,cat looks like he got egg on his face allright!
