The long-tailed reed finch (Donacospiza albifrons) is a species of South American bird in the tanager family Thraupidae. It is the only member of its genus Donacospiza. It is found in Argentina, Bolivia, Brazil, Paraguay, and Uruguay.
Its natural habitats are temperate grassland, subtropical or tropical seasonally wet or flooded lowland grassland, and swamps. The long-tailed reed finch was formally described in 1817 by the French ornithologist Louis Pierre Vieillot under the binomial name Sylvia albifrons. Vieillot based his description on the Cola Aguda del Vientre de Canela that had been described by the Spanish naturalist Félix de Azara in 1805 based on a specimen obtained in Paraguay. The long-tailed reed finch is now the only member of the genus Donacospiza that was introduced in 1851 by the German ornithologist Jean Cabanis. The genus name combines the Ancient Greek donax meaning "reed" or "cane" with spiza meaning "finch". The specific epithet combines the Latin albus meaning "white" with frons meaning "forehead" or "front". The species is monotypic: no subspecies are recognised.

It is the 319th most-seen of the 353 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Long-tailed Reed Finch in São Paulo on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Long-tailed Reed Finch is recorded against all the birds logged in São Paulo (7 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.
