cerceta pardilla (Marmaronetta angustirostris) marbled teal

The marbled duck, or marbled teal (Marmaronetta angustirostris) is a threatened, medium-sized species of duck from southern Europe, northern Africa, and western and central Asia.The scientific name, Marmaronetta angustirostris, comes from the Greek marmaros, marbled and netta, a duck, and Latin angustus, narrow or small and -rostris billed.
This duck formerly bred in large numbers in the Mediterranean region, but is now restricted to a few sites in southern Spain, southern Italy, northwest Africa and the broader Levant. Further east it survives in the Mesopotamian marshland in southern Iraq and in Iran (Shadegan Marshes - the world's most important site), as well as isolated pockets in Armenia, Azerbaijan, western India and western China. In general the species has nomadic tendencies. In some areas birds disperse from the breeding grounds, and have been encountered in the winter period in the Sahel zone, south of the Sahara.
Its preferred breeding habitat is temporary and shallow fresh, brackish or alkaline waters with densely vegetated shores in regions that otherwise are fairly dry. It may also breed in coastal lagoons, along slow rivers or man-made waters like reservoirs. The on average c. 12 eggs are placed in a nest covered by dense vegetation at the waters edge. It is usually on the ground, but occasionally higher among reeds or on huts made from reeds.They are common in captive collections but are a nervous and flighty bird.
