Black-necked Grebe (Zampullín Cullinegro / Podiceps nigricollis).
Uncommon winter visitor in areas 3, 6 and 9 with the odd birds staying long enough to be seen in summer plumage. Not an easy bird to find in the area and rarely more than a single bird which is surprising as it can be quite common not that far away on Lagoons on the border with Malaga.
Little Grebe (Zampullín Común / Tachybaptus ruficollis).
Regular breeding species in areas 3, 6 and 9, also a Common winter visitor possible in all areas.
Great Crested Grebe (Somormujo Lavanco / Podiceps cristatus).
Uncommon winter visitor to area 6 and 9. Odd birds turn up on the Contra-embalse de Bermejalis and on the main Bermejalis Embalse.
