When it comes to birds that lay blue eggs, two common species that often come to mind are the Song Thrush and the Mistle Thrush. Both belonging to the Turdidae family, these birds share some similarities but also have distinct characteristics that set them apart.

The Song Thrush, scientifically known as Turdus philomelos, is a small to medium-sized bird that can be found throughout Europe and parts of Asia. It is known for its beautiful song, which is a melodious combination of different notes. In terms of egg-laying, Song Thrushes are known to lay blue eggs with speckles or spots. The blue coloration is caused by a pigment called biliverdin, which is also responsible for the blue color in robin eggs. The speckles or spots on the eggs serve as a form of camouflage, helping to protect them from predators.

On the other hand, the Mistle Thrush, scientifically known as Turdus viscivorus, is a larger bird that is commonly found in Europe, North Africa, and parts of Asia. It gets its name from its fondness for eating mistletoe berries. Mistle Thrushes are known to lay eggs that are pale blue or greenish-blue in color. These eggs are typically unspotted, but some may have faint markings. The blue coloration in their eggs is also due to the presence of biliverdin.

While both the Song Thrush and the Mistle Thrush lay blue eggs, their shades of blue and the presence or absence of speckles differ. The Song Thrush tends to have more heavily speckled eggs compared to the Mistle Thrush, which usually has unspotted or lightly marked eggs.

So, in conclusion, both the Song Thrush and the Mistle Thrush lay blue eggs. However, if you're looking for heavily speckled blue eggs, you're more likely to find them among the Song Thrush nests. On the other hand, if you come across pale blue or greenish-blue eggs with minimal markings, you're observing the eggs of a Mistle Thrush.
