The Sado Estuary is an excellent area for birdwatching, receiving as many as 50,000 birds during the winter.
The spoonbill, little merganser, heron, western marsh harrier, black-winged stilt and flamingo are a few which stand out among the resident and migratory species.
“Herdade da Mourisca” and the Mourisca Tide Mill, which in itself is worth a visit, provide excellent spots for birdwatching.
Birdwatching enthusiasts may choose to take part in walking trails or boat trips, organised by duly licensed tour operators.
A sedentary population of bottlenose dolphins inhabits the Sado Estuary, the only place in mainland Portugal and one of the few places in Europe inhabited by this species.
These mammals can easily be spotted in small groups in the estuary and coastal area.
Duly licensed companies should always be used for Sado dolphin watching, as these agents ensure compliance with the Code of Conduct that should be adopted when watching the dolphins in the water, and if they approach the boats.
