The southern red bat (Lasiurus blossevillii) is a species of microbat found in South America. Previously, the western red bat (L. frantzii) was classified as a subspecies of the southern red bat, but phylogenetic evidence supports it being a distinct species. This has been followed by the American Society of Mammalogists and the ITIS.
It was named after French explorer Jules de Blosseville. The species is recorded in Argentina, Bolivia, Brazil, Colombia, Ecuador (Galápagos Islands), French Guiana, Guyana, Paraguay, Peru, Suriname, Trinidad and Tobago, Uruguay and Venezuela. Eastern red bat – Lasiurus borealis

Rare
Under 5% of wildlife watchers report a Southern red bat sighting in Buenos Aires on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 9th most-seen of the 15 mammals we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
March–April, July and September
In those months about 10% of wildlife watchers report a Southern red bat in Buenos Aires on a given day, against under 5% in May–June, August and October–February, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Southern red bat sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Buenos Aires, in our data
Buenos Aires is the only city on Wallace's Line with enough records to rate Southern red bat sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Southern red bat is recorded against all the mammals logged in Buenos Aires (14 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.
