Anyone good at bird egg ID?

[bloodywhitecat]

I know it's not a chicken's egg for sure! Is it a nuthatch egg?

How big is it @bloodywhitecat ? At first glance it looks like a Moorhen or Coot egg, if it is roughly the same size as a small chicken egg

No, smaller than a small chicken egg. Nowhere near moorhens or coots but there are nuthatch in the tree nearby which is why I wondered about nuthatch (but there are crows in the same tree)

This is it

Is it light blue? If so I'd be thinking blackbird.

Hmm, now it's in the palm of your hand I think it might be a bit big for a black bird(unless you have v. small hands )!

It's paler than any blackbird egg I have seen

Linnets have pale blue with splodges (the use of this highly technical term is evidence of my expert credentials). They're about the right size too.

looks a bit like a jackdaw egg to me OP.
25mm x 36mm

do you have the actual size?

I reckon magpie. Too big for your small songbirds.

Next to a AAA battery for size comparison

Or jackdaw like @shootfromthehip145 says.

I don't think it loaded

Cracking little book if you can find it cheap second hand, I use it for work. 🙂

Not sure that it is either a Jackdaw or Magpie - all the Corvid eggs tend to be a pale blue background colour, as are thrush, blackbird and starling eggs, although it is around the right size for the latter three...

I think your first thought that it might be a Nuthatch egg is possibly correct - it is about the right size, colouring and would make sense if you have Nuthatches nearby, plus crows! It is not a hatched egg and has clearly been predated by the crows, or possibly a squirrel

We have a nuthatch pair in that tree, I regularly see them going in and out of a hole high up. Crows are in a hollowed out branch on the other side and we regularly have a squirrel that scampers across the telephone wires near the trees.
