Whose egg?

[missesbell]

We found three eggs on the ground in the garden. About 45mm long (Smaller than a chickens egg) and almost olive green with no speckles. Any ideas which species laid them? I think they had been predated by a crow.

Blackbird.

[missesbell]

Much too big for a blackbird

[4getmenot]

yer crows eggs are a light blue/green colour, very light. I wouldnt say olive. Sometimes have speckles, sometimes not

[lslowry]

could be a pheasants egg

[Milvus]

As 4getmenot says crows, and in particular Jays are a possibility, but both have speckles.
My fancy is that they are Mallard eggs
