Peedie tern eggs

I think these are Peedie (little) tern eggs. They certainly look like the references I can see online and there is a small colony of them nesting in the area where we spotted them.

When I say spotted, I mean nearly stood on. Not sure a small depression in the sand, beautiful lined with broken shells and seaweeds but very near the tide line is the safest place for a nest but hopefully the young will make it.
