|Rio Grande do Sul, Brazil
The Rosy-billed Pochard is partially migratory with populations all year round in central Chile and northern Argentina with Uruguay and the extreme south of Brazil, but with the south Argentina population migrating northward during the austral winter.
|These photos are of the male showing the rosy red bill with dark "nail" and the red iris. I do not know if there is any significance in the different size of red "knob" above the bills of the males in the top photo but suspect it might be a sign of sexual prowess. The female looks totally different and is generally brown with a grey bill.
They feed mainly on seeds, roots and aquatic plants which they eat by dabbling mainly though they do sometimes dive.
