Eggshell

This eggshell fragment was laying on the moss at the edge of a gravel bar on Indian River shortly above the second bridge. Given the size and color, I figured it must be a thrush egg. However, it seems a bit too early for Hermit Thrushes and especially Swainson’s Thrushes to have nestlings. American Robin eggs are pure blue, and the book I have about eggs and nestlings shows Varied Thrush eggs being pure blue as well. I took a look on the Birds of North America On-line account of Varied Thrush and found a photo there of eggs with light speckling. Though that example was not nearly as speckled as this, given the time and location, my best guess is this was from a recently hatched Varied Thrush. I do not expect the nest was particularly close, as it is my understanding that many bird parents will carry such things away from the nest in an effort to help avoid detection and predation of their young.
