What bird lays a light blue egg?

Can you tell me which avian species is known for producing eggs with a distinct light blue hue? I'm particularly intrigued by this unusual coloration in avian reproduction and would love to learn more about the specific bird that lays such eggs. Is there a particular family or genus of birds that are renowned for this trait, or is it a more rare occurrence? I'm eager to gain insight into this fascinating aspect of bird biology.
