The plumbeous rail (Pardirallus sanguinolentus) is a species of bird in the subfamily Rallinae of the rail, crake, and coot family Rallidae. It is found in Argentina, Bolivia, Brazil, Chile, Ecuador, Paraguay, Peru and Uruguay.
The plumbeous rail has previously been placed in the large genus Rallus, and also in genus Orygonax with the blackish rail (Pardirallus nigricans). Some authors propose that the blackish and plumbeous rails are conspecific, and they do form a superspecies. The plumbeous rail has these six subspecies:
Pardirallus sanguinolentus simonsi Chubb, C., 1918 Pardirallus sanguinolentus tschudii Chubb, C., 1919 Pardirallus sanguinolentus zelebori (Pelzeln, 1865) Pardirallus sanguinolentus sanguinolentus (Swainson, 1838) Pardirallus sanguinolentus landbecki (Hellmayr, 1932)
Pardirallus sanguinolentus luridus (Peale, 1849) The blackish rail is 30 to 38 cm (12 to 15 in) long and weighs 170 to 230 g (6.0 to 8.1 oz). The sexes are alike. They have red eyes and legs. They have a green bill and in all but subspecies P. s. luridus the maxilla has a sky blue base and the mandible a bright red one. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Plumbeous Rail is recorded against all the birds logged in Montevideo (47 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.
