Birds are known for their diverse and vibrant egg colors, with blue being one of the most fascinating. This captivating color not only adds to the beauty of bird nests but also serves various evolutionary purposes, such as camouflage and signaling the health of the mother. Let's explore the remarkable birds that lay blue eggs, spanning across different continents and habitats.


Eastern Bluebird

The Eastern Bluebird lays eggs that are typically light blue in color, although occasionally, white eggs can occur. The eggs are smooth and slightly glossy, usually measuring about 0.83 inches in length and 0.63 inches in width. A typical clutch consists of 3 to 7 eggs, which the female incubates for about 13 to 16 days. These blue eggs are laid in nests made of grasses, pine needles, and other plant materials, often in tree cavities or nest boxes provided by humans.
