Photo by J.H. Ribot, at the place of the Kalpoe family, Kalpoeweg Suriname 1984. Formerly you could hear large groups of whistling-ducks pass over Paramaribo at night. After much hunting, the groups are normally much smaller now, although groups of thousands can be seen sometimes in March. They are found in lagoons and will feed at night, sometimes in rice-fields. These ducks can be found perching in trees, deserving them the name 'tree-duck'. Nests have been found in holes of mangrove trees, sometimes with many (more than 10) eggs.
Each small square indicates the observation of at least one (group) of these birds, the medium ones at least 4 observations on different days and the largest ones 10 or more. The color of each square indicates: blue for coastal area, yellow for savanna and red for rainforest. Sometimes groups of 2000 birds can be found (Ottema 2002).
Photo made in the zoo of mr. Fung, Nieuw Nickerie(Ribot).
