The austral negrito or Patagonian negrito (Lessonia rufa) is a species of bird in the family Tyrannidae. It breeds in Argentina and Chile, migrating north as far as Bolivia, southern Brazil, Paraguay and Uruguay. It is a vagrant to the Falkland Islands and the South Georgia and the South Sandwich Islands territory. It has also been seen in the South Shetland Islands. [2] Its natural habitats are freshwater lakes and saline marshes. It is primarily insectivorous [3] but can eat algae. [2] It hunts in grassland environments with short grass. [4] It perches and moves throughout foliage such as shrubs in order to find prey. [3]
The austral negrito 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 larks in the genus Alauda and coined the binomial name Alauda rufa. [5] [6] The specific epithet is from Latin rufus meaning "red", "ruddy" or "rufous". [7] Gmelin based his description on "L'alouette noire à dos fauve" from Buenos Aires that had been described in 1778 by the French polymath, the Comte de Buffon and illustrated with a hand-coloured engraving by François-Nicolas Martinet. [8] [9] The austral negrito is now placed together with the Andean negrito in the genus Lessonia that was introduced in 1832 by William Swainson. [10] The species is monotypic: no subspecies are recognised. [10]
