Fulica ardesiaca
The Andean Coot, *Fulica ardesiaca*, is a medium-sized, dark slate-gray waterbird measuring approximately 43 to 48 centimeters in length and weighing between 600 and 800 grams. Its most distinctive field mark is a prominent yellowish-orange frontal shield and bill, often adorned with a darker, sometimes reddish, band near the tip. Striking reddish eyes provide a stark contrast to its dark plumage, and its white undertail coverts are noticeable during preening or when it raises its tail. Taxon...
This species exclusively inhabits high-altitude freshwater lakes, ponds, and slow-moving rivers. It is predominantly found in Andean wetlands and inter-Andean valleys, typically at elevations ranging from 2,500 to 4,800 meters above sea level.
The Andean Coot primarily consumes aquatic vegetation, including algae, submerged shoots, and seeds, supplemented by aquatic invertebrates, insect larvae, and occasionally small fish. It forages by diving and dabbling in open water and along shallow shores.
Andean Coots are primarily diurnal, spending their days foraging in open water and along shorelines, often congregating in large flocks outside the breeding season. Their foraging strategy involves frequent diving to access submerged aquatic vegetation and invertebrates, as well as dabbling at th...
