There was something about this hatched egg I encountered while hiking through the Douglas Family Preserve in Santa Barbara. First, it was in the open, not near a tree, more like a dinosaur egg than one for a bird. Secondly, it was the brightest white, but that might be due to the bright sun overhead. Finally, I don’t know much about eggs. Quail eggs are much smaller and speckled. Other bird shells I find by trees are also small and off-white. This area has gopher snakes, but the shells are oblong, but then I only have half a shell to judge by. Given the location I’d guess the egg was snatched from the nest, say from a brown pelican–the preserve abuts the Pacific Ocean where brown pelicans glide along the coast. And, maybe it was from a supermarket. Please post the answer.
