Black Stork vs White Stork

In short

The Black Stork (Ciconia nigra) and White Stork (Ciconia ciconia) are both large wading birds, but they can be distinguished by their plumage: the Black Stork has a mostly black body with a white belly, while the White Stork is predominantly white with black flight feathers. Observing their preferred habitats can also help; Black Storks are more often found in forested areas, whereas White Storks are typically seen in open fields and wetlands.
