Hi All - any thoughts on which bird may have laid this egg. I live on the Sunshine Coast not far from the coast - it is only hlf the egg so I am presuming that it has hatched. I could not see any nests nearby so int is possible that it may have come in on the wind. We have had a pair of plovers on the front lawn but I suspect it is a bit small for a plovers egg.
I'm no expert but I think it might be a Welcome Swallow egg. Hope that helps!
