Common shelduck
The Common shelduck is a migratory species, nesting in northern Europe and migrating south to winter in milder areas such as the Danube Delta. Nests are often built in tree bark and the female typically lays 7-12 eggs. These birds are monogamous and show territorial behaviour, especially during the nesting season. In late summer, thousands of white caliphs gather to nest in safe, remote areas.

Description and how to observe Common shelduck:
The Common shelduck, scientifically known as the Tadorna tadorna, is a waterbird impressive in size and colouring. It is distinguished by its contrasting white feathers, with a black band on its breast and head, and a red spot at the base of its beak. It is often seen on the sandy banks and open water areas of the Danube Delta. It is easiest to spot in the early morning or evening, when it prefers to feed or rest on the sandy banks.
What it feeds on Common shelduck:
The Common shelduck has a varied diet, suitable for foraging in soft ground for larvae and invertebrates as well as for crustaceans and molluscs in the water. This diversity in diet makes it adaptable to different aquatic environments.
Threats:
The main threats to the Common shelduck include habitat loss due to wetland drainage and water pollution. Human disturbance and illegal hunting also pose significant risks to the species. Climate change, affecting migration patterns and food availability, is also an emerging challenge to its survival.
Ecological role:
The Common shelduck plays a vital ecological role in aquatic ecosystems. Through their feeding activities, they help control invertebrate populations and contribute to the overall health of freshwater and saltwater habitats. Their presence is also a good indicator of ecological environmental quality.
