On my regular walk through Seward Park this afternoon I came across a partial
(about 1/3) eggshell on the path under a fairly heavy canopy of doug fir,
big-leaf maple and madrona. It was robin's egg blue with heavy brown
streaks/speckles and perhaps half again the size of a robin's egg. The interior was creamy
colored.

Interestingly, the inside was still wet with albumin. There was a puddle of
wet next to it, but no definite yolk nor any sign of an embryo.

Anybody out there have any ideas about 1. species, and 2. how it might have
landed there? Sloppy laying technique? Fratricide? Parasitism?

Any suggestions for books that describe eggs?
