  • When is the best time of the year to do birdwatching at EVOA?

    It is possible to observe birds at EVOA all year long.

    Some of the birds are resident, it means that can be observed during all year. But the mojority of our birds are migrantory.

    Between november and february we receive a big amount of birds that come from Northern Europe. At this time of year we can observe thousands of birds from big diversity of species, in flight ou resting in the lagoons.

    In march, april and from august to october the passage several species of migratory birds brings surprises to our lagoons every day, it can be observed peaks of diversity. However, during this months the densities of birds are not constant.

    In the months of may and june we can se birds that come from Africa, some of them to reproduce in our lagoons. And thus it is possible to observe nestlings/chicks (?) of waders and ducks. However, it is unusual to observe numerous flocks because the individuals are more disperse e trying to keep themselves  undetected.
