Again in the Reservoir

Again in reservoir of the river Ebro, a morning of good birding, with a number not a lot of species but good in speciments, mainly of the best contributed with 150 Greylag Goose (Anser anser) as always grazing in the north coast of the dam. All week I have news about the good numbers of Greylag Goose, 250, 180,…
Small flocks of other ducks, Gadwall (Anas strepera) one of the flocks of 26 birds, Common Teal (Anas crecca) this time unlike others, few units, Mallard (Anas platyrhynchos), small groups of few distributed units but in several zones.
Is strange to confirm, the Red-crested Pochard (Netta rufina) has a terrible reduction, in years ago the Red-crested Pochard was like one of most numerous in wintertime, thousands of birds, today only eight birds !!!!.

Also eight Tufted Duck (Aythya fuligula) near Reinosa.
Great Crested Grebe (Podiceps cristatus), one of the most representative birds of this dam.
