The southern martin (Progne elegans) is a species of bird in the family Hirundinidae, the swallows and martins. One source states that it is known in every mainland South American country except Colombia, Guyana, and Venezuela, and there are undocumented sight records in those three countries. It has occurred as a vagrant in the Malvinas/Falkland Islands and the U.S. state of Florida
The southern martin was originally described with its present binomial Progne elegans. For much of the twentieth century many authors treated the southern martin and Peruvian martin (P. murphyi) as conspecific with the Galapagos martin (P. modesta).
The southern martin is monotypic. The southern martin is 17 to 20 cm (6.7 to 7.9 in) long. The sexes are dimorphic though both have a deeply forked tail. Adult males are almost entirely glossy steel-blue with blacker wings and tail. Females have duller steel-blue upperparts than males. Their underparts are mostly dusky brown with paler feather edges that give a scaly appearance; their undertail coverts are white with dusky streaks. Juveniles resemble adult females.

Rare
Under 5% of wildlife watchers report a Southern Martin sighting in Buenos Aires on a given day, based on 171 verified sightings from GBIF citizen-science data. It is the 178th most-seen of the 274 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Southern Martin in Buenos Aires on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Southern Martin sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 5
Of the 5 cities where we can rate Southern Martin sightings, Buenos Aires ranks 3rd at under 5%. The best odds are in Mendoza (Argentina, about 30%) and Cordoba (Argentina, about 20%).
Same genus: Progne

GBIF citizen-science records
It is estimated from how often the Southern Martin is recorded against all the birds logged in Buenos Aires (171 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.
