Dear Tweeters,
This morning (the 4th of July) there was a bird's egg on my gravel driveway. Actually, it was just two thirds of an eggshell. It looks like  it comes from the "big end" of the shell, as a Blefuscudian might have called it. The shell is an ivory color, white with just a tiny hint of creamy color. I estimate that the intact egg would have been about 30 cm long, and 22 cm broad at its broadest. The eggshell was not there on Friday afternoon, so I am guessing that it was dropped there late yesterday evening or early this morning, either by a parent bird, or by a nest predator. Inside of the eggshell, remnants of a network of membrane is visible, mostly blood-colored; the inside of the eggshell is the same color as the outside.
I have a guess as to what species this came from, but I thought I'd put it out for other Tweeters' suggestions. If I'm not mistaken, most of the birds in my neck of the woods, near Lyman in Skagit County, would lay colored eggs.
Yours truly,
Gary Bletsch
