The marbled duck (Marmaronetta angustirostris) is a bird species belonging to the Anatidae family that inhabits wetlands across Eurasia and Africa.
Its diet consists mainly of seeds and small aquatic invertebrates. It has mottled brown plumage, a dark mask on its face, and a distinctive tuft at the back of its neck.
In recent decades, its population has declined alarmingly in the Iberian Peninsula, and it is currently listed as CR (Critically Endangered) as a breeding species in Spain.
Last December, I was lucky enough to observe a group of 12 individuals resting in the Tablas de Daimiel National Park (Ciudad Real, Castilla-La Mancha).
