During the winter and migrations the estuary has a great value for waterbirds, notably for Recurvirostra avosetta with more than 700 individuals.this site has two breeding couples of Circus aeruginosus, the number of this species rises during the winter.Very records of Pandion haliaetus confirm the importance of this site as wintering and passage migratory place.Also ardea purpurea is here during breeding season

Pressure/threats to key biodiversity
Excessive flux of nutrients from agriculture of Baixo Mondego Valley cause filling-in. There is a gradual transformation of actives salt marshes(salinas) in aquaculture or abandoned salt marshes what reduce the feeding and nesting habitat for waders.Hunting of waders and flamingos has been registered.
