Red-billed teal

The red-billed teal 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 all the other ducks, geese and swans in the genus Anas and coined the binomial name Anas erythrorhyncha.{{ cite book | last=Gmelin | first=Johann Friedrich | author-link=Johann Friedrich Gmelin| year=1789 | title=Systema naturae per regna tria naturae : secundum classes, ordines, genera, species, cum characteribus, differentiis, synonymis, locis | edition=13th | volume=1, Part 2 | language=Latin | location=Lipsiae [Leipzig] | publisher=Georg.

The red-billed teal is {{convert|43|–|48|cm|in}} long and has a blackish cap and nape, contrasting pale face, and bright red bill. The body plumage is a dull dark brown scalloped with white. Flight reveals that the secondary flight feathers are buff with a black stripe across them. The sexes are similar, but juveniles are duller than adults.

This is a quiet species, but the displaying male has a whzzt call, whereas the female has a soft mallard-like quack.

The red-billed teal is a bird of freshwater habitats in fairly open country and is an omnivore. It feeds by dabbling for plant food, or foraging on land mainly in the evening or at night. It nests on the ground in dense vegetation near water.

This is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
