The cotton pygmy goose or cotton teal (Nettapus coromandelianus) is a small perching duck which breeds in South and Southeast Asia extending to Queensland in Australia where they are sometimes called white-quilled pygmy goose. They are among the smallest waterfowl in the world and are found in small to large waterbodies with good aquatic vegetation. They are usually seen in pairs or larger groups of pairs, roosting and nesting on trees near water. They are strong fliers and are known to disperse widely, especially in winter. Their breeding season coincides with the rains.
The cotton pygmy goose was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the ducks, swans and geese in the genus Anas and coined the binomial name Anas coromandeliana. Gmelin based his description on "La Sarcelle de Coromandel" that had been described in 1783 by the French polymath Georges-Louis Leclerc, Comte de Buffon in his Histoire Naturelle des Oiseaux. Hand-coloured plates had been published separately. The cotton pygmy goose is now one of three species placed in the genus Nettapus... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Cotton Pygmy-Goose is recorded against all the birds logged in Thiruvananthapuram (99 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
