Man and the Earth S02 E64 Doñana National Park II

We can see how the Guadalquivir marshlands begin their biological cycle with the first autumn rains. Throughout the year, European and African migratory species find refuge here: ducks, geese, herons, little egrets, spoonbills, avocets, gull-billed terns... they nest and breed in these marshlands. Here too the imperial eagle breeds in April, and in summer the fallow deer's mating displays take place.
