Through the visit to Badoka Park, was imposed on us a job to report a story about an animal that we saw on that site. I decided to choose Tadorna ferruginea.
This animal is a bird of great size, looks like a goose, the beak is black, the legs are pink plumage is the predominant color of rust and infra-caudal part white.
It is a wintering bird, because it presents more frequently from November to February and arrive in Portugal, through acts migratory, coming from Western Europe. Sometimes accidentally come to the Azores and / or Madeira.
This bird is a rare occurrence and something irregular. It is distributed in a very localized along the coastal strip is very rare in the countryside. They are usually numbered fewer than 100 individuals annually, in December 1995 noted an exceptional number of 850 birds. The Tagus Estuary is home to almost the entire population of the species in our country and is the only area where their presence can be considered regular.
The habitat of Tadorna are intertidal zones in estuaries, salt marshes and fish farms, and sometimes occasionally dams in the interior areas.
These animals feed mainly on aquatic invertebrates (molluscs, insects and crustaceans), although also feed on small fish, eggs, worms and plant matter. The food is obtained by walking in shallow water or mud between tides.
As for breeding occurs in early May to late June, sometimes in March usually put two clutches per year. The nest is installed in pits in the ground or in trees, often using the burrows dug by the rabbits. The postures consist of 8-15 eggs. The incubation period lasts 29-31 days. The cubs are able to fly after 45-50 days.
