STORKS

White Stork
The White Stork (Ciconia ciconia) is a large bird in the stork family Ciconiidae. Its plumage is mainly white, with black on its wings. Adults have long red legs and long pointed red beaks, and measure on average 100–115 cm (39–45 in) from beak tip to end of tail, with a 195–215 cm (77–85 in) wingspan. The two subspecies, which differ slightly in size, breed in the warmer parts of Europe (north to Estonia), northwestern Africa, southwestern Asia (east to southern Kazakhstan), and southern Africa. The White Stork is a long-distance migrant, wintering in Africa from tropical Sub-Saharan Africa to as far south as South Africa, or on the Indian subcontinent. When migrating between Europe and Africa, it avoids crossing the Mediterranean Sea and detours via the Levant in the east or the Strait of Gibraltar in the west, because the air thermals on which it depends do not form over water.
The Black Stork Ciconia nigra is a large wading bird in the stork family Ciconiidae. It is a widespread, but rare, species that breeds in the warmer parts of Europe, predominantly in central and eastern regions. This is a shy and wary species, unlike the closely related White Stork. It is seen in pairs or small flocks—in marshy areas, rivers or inland waters—often in association with White Storks. The Black Stork feeds on amphibians and insects.
